Every parent knows the drill. The sun goes down, and suddenly your toddler becomes a hyperactive night owl or your school aged child starts negotiating for “just five more minutes.” Sleep troubles in children are incredibly common, but they can take a toll on the whole family’s wellbeing.

Quality sleep is essential for your child’s growth, learning, and emotional development. According to the CDC, school aged children need between 9 and 12 hours of sleep per 24 hour period, while teenagers require 8 to 10 hours. Yet many kids struggle to get the rest they need.

The good news? Most childhood sleep problems can be solved with the right approach. This guide will walk you through the most common issues and provide practical, evidence based solutions to help your child (and you) get the sleep everyone needs.

Understanding how much sleep your child needs

Before tackling sleep problems, it’s important to know what “enough sleep” actually means for your child’s age. The American Academy of Sleep Medicine provides these guidelines:

Getting adequate sleep helps children with attention, behaviour, learning, memory, and emotional regulation. Research shows that insufficient sleep is linked to injuries, high blood pressure, obesity, and mental health issues including depression.

Bedtime resistance: When kids won’t go to sleep

One of the most frustrating challenges parents face is the nightly battle to get children into bed. Your child might suddenly need water, have to go to the toilet again, or insist they’re “not even tired.”

Why it happens

Bedtime resistance can stem from several causes: fear of missing out (especially if older siblings are still awake), anxiety about separating from parents, overtiredness (which paradoxically makes it harder to settle), or simply not having a consistent routine.

What you can do

Create a predictable bedtime routine. Children thrive on consistency. Establish a calming sequence of events that happens at the same time every night. For preschoolers, this might include a bath, brushing teeth, putting on pyjamas, and reading a story together. The routine should take 20 to 30 minutes and avoid anything stimulating like screens or active play.

Set clear boundaries. Once you’ve said goodnight and left the room, resist the urge to return every time your child calls out. If your child is safe and their needs are met, give them the time and space to settle themselves. If they get out of bed, calmly guide them back without engaging in conversation or negotiation.

Make bedtime the same time every night. A regular sleep schedule helps regulate your child’s internal clock, making it easier for them to fall asleep naturally.

Address underlying fears. If your child expresses anxiety about the dark or being alone, acknowledge their feelings. A small nightlight or leaving the door slightly ajar can provide reassurance without disrupting sleep.

Night wakings: helping your child sleep through

It’s normal for children to wake briefly during the night, but some struggle to get back to sleep on their own. This can lead to disrupted sleep for the entire household.

The sleep cycle connection

Understanding sleep cycles helps explain why this happens. During the night, we all move through different stages of sleep, and it’s natural to briefly wake between cycles. Children who haven’t learned to self soothe may call out for a parent during these moments.

Strategies for better sleep

Encourage self settling from the start. When putting your child to bed, leave while they’re drowsy but still awake. This teaches them to fall asleep independently, which is the same skill they’ll need when they wake during the night.

Keep night interactions minimal. If your child wakes and calls for you, check that they’re safe and comfortable, but keep your response brief and boring. No lights, no conversation, no engaging activities.

Rule out physical causes. Frequent night waking can sometimes signal an underlying issue like sleep apnea, reflux, or discomfort. If the problem persists despite good sleep habits, consult your GP.

Nightmares and night terrors: Understanding the difference

Both nightmares and night terrors can be distressing, but they’re actually quite different experiences that require different responses.

Nightmares

Nightmares are scary dreams that happen during REM (rapid eye movement) sleep, usually in the second half of the night. Your child will wake up, remember the dream, and feel frightened. They can tell you what scared them and will seek comfort from you.

How to help: Stay calm and reassure your child that the nightmare wasn’t real. Offer comfort through a hug, soothing words, or their favourite stuffed toy. You might need to check under the bed or in the cupboard to reassure them that everything’s safe. The next day, talking about the dream or even drawing it can help reduce its power.

To prevent nightmares, avoid scary movies or stories before bed, maintain a regular sleep schedule, and help your child manage any stress or worries they might be experiencing.

Night Terrors

Night terrors happen during deep non REM sleep, typically 2 to 3 hours after falling asleep. During an episode, your child might sit up, scream, thrash around, or seem terrified, but they’re not actually awake. Their eyes may be open, but they won’t recognise you or respond to comfort. Most importantly, they won’t remember the episode in the morning.

How to help: Don’t try to wake your child during a night terror. Instead, sit quietly nearby and make sure they don’t hurt themselves. The episode will typically end on its own within a few minutes, and your child will go back to sleep.

Night terrors are often triggered by overtiredness, stress, or irregular sleep schedules. Ensuring your child gets enough sleep and maintaining a consistent bedtime can help prevent them. If night terrors happen around the same time each night, you can try gently waking your child 15 to 30 minutes beforehand.

When to see a doctor: If night terrors last longer than 30 minutes, happen more than once a week, or are accompanied by drooling, stiffening, or jerking movements, consult your child’s healthcare provider.

Sleepwalking: Keeping your child safe

Sleepwalking affects up to 15% of children and is most common between ages 4 and 12. During an episode, your child might sit up, walk around, or perform other activities while still asleep.

Safety first

The main concern with sleepwalking is safety. Children who sleepwalk aren’t aware of their surroundings and could potentially hurt themselves.

Create a safe environment:

During an episode: Don’t try to wake your sleepwalking child, as this can be disorienting and frightening. Instead, gently guide them back to bed with minimal interaction.

Prevention strategies: Maintain a regular sleep schedule, ensure your child gets enough sleep, and address any sources of stress. Overtiredness is a common trigger for sleepwalking episodes.

Most children naturally outgrow sleepwalking as their sleep patterns mature. However, if episodes are frequent, dangerous, or persist into the teenage years, talk to your doctor about possible treatments.

Sleep apnea: When snoring is a red flag

While occasional snoring is common, loud and frequent snoring can signal obstructive sleep apnea, a condition where breathing repeatedly stops and starts during sleep. This affects approximately 15 to 20% of children.

Warning signs

Watch for these symptoms:

During sleep:

During the day:

Why it matters

Untreated sleep apnea can lead to serious health consequences including impaired growth, high blood pressure, learning difficulties, and increased risk of heart problems. The condition is often caused by enlarged tonsils or adenoids, obesity, or certain medical conditions like Down syndrome.

Getting help

If you suspect your child has sleep apnea, see your GP. Diagnosis typically requires a sleep study, and treatment might include removing tonsils and adenoids, using a CPAP machine, weight management strategies, or other interventions depending on the underlying cause.

Managing melatonin: What parents should know

With rising awareness of children’s sleep struggles, many parents are turning to melatonin supplements. However, it’s crucial to understand both the benefits and limitations of this approach.

Important safety information

Melatonin is not a sleeping pill. It’s a hormone that signals the body it’s time to sleep, but it won’t knock your child out. More concerning, melatonin supplements aren’t regulated by the FDA, meaning the actual contents and dosages can vary significantly from what’s listed on the label.

From 2012 to 2021, there were over 260,000 reports of melatonin poisoning in children. While most cases resulted in no serious symptoms, some children required hospital care. Always store melatonin and all supplements safely out of children’s reach.

When it might help

Melatonin may be appropriate as a short term solution while you establish better sleep habits. It can also help reset sleep schedules after holidays or help teenagers whose natural sleep cycles make early morning wake ups difficult. For children with ADHD or autism, melatonin may offer benefits, but this should be carefully monitored by a paediatrician.

Dosing guidelines

If you and your child’s doctor decide to try melatonin:

Long term safety data in children is limited, particularly regarding effects on growth and development during puberty. Always consult your child’s healthcare provider before starting melatonin.

The screen time connection

One of the biggest sleep disruptors for modern children is screen exposure before bed. Blue light from tablets, smartphones, and computers tricks the brain into thinking it’s daytime, suppressing natural melatonin production and making it harder to fall asleep.

The American Academy of Pediatrics recommends avoiding screen time for at least one hour before bed. This includes television, video games, and social media. Using devices past bedtime, especially for violent games or shows, can further interfere with sleep quality.

Creating a sleep friendly environment

Your child’s bedroom setup plays a significant role in sleep quality. Here’s how to optimise it:

Temperature and light: Keep the room cool (around 18°C) and dark. Blackout curtains can help, as can a dim nightlight if your child prefers one.

Comfort matters: Ensure your child’s mattress provides proper support. Young children are lighter than adults, so a mattress that feels soft to you might be just right for them. The Dreamland Liverpool, for example, offers two layers of comfort in pocket spring construction, available in single and king single sizes perfect for growing kids.

Minimise disruptions: Keep the bedroom quiet and remove potential distractions like toys or screens that might tempt your child out of bed.

When to seek professional help

While most sleep problems resolve with consistency and the strategies outlined above, some situations warrant professional evaluation:

Your GP can help identify any underlying medical issues and refer you to a sleep specialist if needed.

Your path to better sleep starts tonight

Solving your child’s sleep problems won’t happen overnight, but consistency is key. Pick one or two strategies that feel most relevant to your situation and commit to them for at least two weeks before expecting results.

Remember: establishing healthy sleep habits is one of the most valuable gifts you can give your child. The benefits extend far beyond bedtime, supporting their growth, learning, emotional wellbeing, and overall health for years to come.

Start with a consistent bedtime routine, optimise their sleep environment, and be patient with the process. With time and persistence, both you and your child will be sleeping better.

You crush your final match of Fortnite at 11:45 PM, heart still racing from that last second victory. You crawl into bed feeling wired, convinced you’ll fall asleep any second. Two hours later, you’re still staring at the ceiling.

Sound familiar?

Competitive PvP games like Fortnite, PUBG, Brawl Stars, EA FC Mobile, and Rush Royale deliver an adrenaline fueled experience that makes them incredibly fun to play. But when you fire up that final match before bed, you are activating multiple biological systems that directly conflict with sleep. Your heart rate spikes, your brain lights up with strategic thinking, blue light floods your retinas, and your body temperature climbs, all while your circadian rhythm is desperately trying to wind you down for rest.

Let’s break down exactly how competitive gaming before bed affects your sleep quality, and what you can do about it.

The physiology of late night gaming: what’s happening in your body

When you’re deep in a competitive match, your body doesn’t distinguish between a digital battle and a real physical threat. Your sympathetic nervous system activates, triggering a cascade of physiological responses designed to keep you alert, focused, and ready for action.

Heart rate and arousal

Competitive gaming elevates your heart rate significantly. Research published in Frontiers in Neuroscience found that physiological arousal from gaming activity makes it difficult to initiate and maintain sleep. Indices like respiratory rate, blood pressure, and heart rate all increase during gameplay, and they don’t instantly return to baseline the moment you close your laptop.

Fast paced games with high actions per minute (think PUBG firefights or Rush Royale tower defence rounds) induce greater alertness and require sustained attention. This cognitive alertness lingers long after the match ends, impairing your efforts to fall asleep.

Blue light exposure and melatonin suppression

Your phone, tablet, or monitor emits short wavelength blue light, which has a powerful effect on your sleep wake cycle. According to Harvard Health, blue light suppresses melatonin (the hormone that makes you sleepy) for about twice as long as other light wavelengths and shifts your circadian rhythm by up to three hours.

That means scrolling through post match stats or queuing for “just one more game” at 11 PM could delay your body’s natural sleep onset until well past 2 AM, even if you’re in bed with the lights off.

The American Academy of Sleep Medicine recommends avoiding blue light from handheld electronics 30 to 60 minutes before bedtime. Yet their 2025 survey found that over one quarter of adults (26 percent) prioritise screen time over getting the recommended seven hours of sleep each night, and half of adults (50 percent) use a screen while in bed every day.

Body temperature regulation

Your core body temperature naturally drops in the evening as part of your circadian rhythm, signaling to your brain that it is time to sleep. Competitive gaming disrupts this process. The mental and physical engagement involved in PvP matches keeps your body in a heightened state, delaying the natural cooling process required for deep sleep.

Even a short 30 minute session can be enough to interfere with your body’s temperature regulation, making it harder to drift off when you finally do close your eyes.

Stress hormones and the sympathetic nervous system

Winning a clutch round or narrowly avoiding defeat triggers the release of catecholamines (including adrenaline and cortisol), part of your body’s arousal response. These stress hormones are designed to keep you alert and focused, which is fantastic during gameplay but disastrous when you’re trying to fall asleep 20 minutes later.

A systematic review in Frontiers in Neuroscience noted that excessive gaming is broadly associated with longer sleep onset latency, shorter sleep duration, and poor sleep quality. The researchers attributed these effects to the sleep suppressing effect of catecholamines, which operate as part of the physiological arousal response to gaming.

How gaming affects sleep architecture

It’s not just about how long it takes to fall asleep. Gaming before bed also impacts the structure and quality of your sleep once you finally drift off.

Reduced deep sleep and REM sleep

Studies have shown that gaming can lead to reduced slow wave sleep (deep sleep) and rapid eye movement (REM) sleep. Deep sleep is when your body repairs muscle tissue, consolidates memories, and releases growth hormone, critical for athletes and anyone training regularly. REM sleep supports cognitive function, emotional regulation, and motor skill learning.

When you sacrifice these sleep stages for late night gaming, you wake up feeling groggy, sore, and mentally foggy, even if you technically spent eight hours in bed.

Increased sleep onset latency

Sleep onset latency is the time it takes to fall asleep after you turn off the lights. Research from the University of Toronto found that each additional hour of gaming per day delayed bedtime by approximately seven minutes and rise time by nearly 14 minutes. Gamers playing more than one hour per day had a 31 percent increased chance of poor sleep quality compared to non-gamers.

If you’re gaming right before bed, you’re stacking multiple sleep disrupting factors (blue light, arousal, elevated heart rate) on top of each other, significantly extending the time it takes to fall asleep.

Circadian rhythm disruption and “social jet lag”

Gaming at night delays your natural bedtime, which contributes to circadian disruption through a phenomenon called social jet lag. This is the mismatch between your biological clock and your social schedule, usually observed as the difference between sleep timing on workdays versus weekends.

If you’re staying up late gaming on weeknights and then sleeping in on weekends to “catch up,” you’re creating a chronic state of circadian misalignment that affects your mood, performance, and overall health.

The data: how much gaming is too much?

There’s no universal threshold for “problematic” gaming before bed, but the research offers some clues.

According to a study cited in Frontiers in Neuroscience, sleep quality decrements became most pronounced after gaming exceeded one hour per day. Another study found that playing games for more than two hours per day resulted in unfavorable effects on sleep. Interestingly, one adolescent study showed that 50 minutes of gaming per day caused almost no disruption to sleep initiation or maintenance.

The takeaway? If you’re gaming for more than an hour close to bedtime, you’re likely experiencing measurable impacts on your sleep quality. And if you’re playing highly intense, competitive PvP games (where every match could mean victory or defeat), the arousal effect is even stronger.

Competitive gaming vs casual gaming: does intensity matter?

Not all games are created equal. Researchers have proposed the concept of “gaming intensity” as a more important predictor of sleep quality than gaming duration alone.

A fast paced shooter like Fortnite or a high stakes MOBA like Brawl Stars triggers more cognitive alertness and physiological arousal than a slower, more relaxing game. Games with high actions per minute, strategic decision making, and competitive pressure are particularly disruptive to sleep when played in the evening.

If you’re choosing between a casual puzzle game and a ranked PvP match before bed, the puzzle game is far less likely to interfere with your sleep.

Practical strategies to protect your sleep without giving up gaming

You don’t have to quit gaming entirely. You just need to be strategic about when and how you play.

Set a gaming curfew

Aim to finish your last match at least 60 to 90 minutes before your target bedtime. This gives your body time to lower your heart rate, reduce arousal, and start the natural wind down process.

If you can’t commit to 90 minutes, even 30 minutes makes a difference. Use that buffer time for lower intensity activities like stretching, reading, or light meal prep.

Use blue light filters and night mode

Most devices now offer built in blue light filters (Night Shift on iOS, Night Light on Windows, blue light filters on Android). While these won’t completely eliminate the arousal effect of competitive gaming, they can reduce the melatonin suppressing impact of your screen.

Consider investing in blue light blocking glasses if you frequently game in the evening. Studies from the University of Toronto found that people wearing blue light blocking goggles experienced melatonin levels similar to those in dim light, even when exposed to bright screens.

Control your gaming environment

Dim the lights in your gaming space as the evening progresses. Bright overhead lights combined with a glowing screen create a double dose of circadian disruption.

Keep your gaming room cool (around 18°C is ideal for sleep preparation), and avoid eating large meals or consuming caffeine within two to three hours of your planned bedtime.

Wind down with a non screen ritual

After your last match, replace screen time with a calming routine. Try a five minute breathing exercise, a warm shower, or journaling about your day. These activities signal to your brain that it’s time to transition from “game mode” to “sleep mode.”

The 4-7-8 breathing technique is particularly effective: breathe in for four counts, hold for seven, and exhale for eight. Repeat three to four times to activate your parasympathetic nervous system and lower your heart rate.

Track your sleep data

If you wear a fitness tracker or smartwatch (Garmin, Oura, Apple Watch, WHOOP), pay attention to your sleep scores on nights when you game late versus nights when you don’t. You’ll likely notice a clear pattern: longer sleep onset latency, reduced deep sleep, and lower overall sleep quality after late night gaming sessions.

Use this data to motivate yourself to stick to your gaming curfew. When you see the direct impact on your recovery and next day performance, it becomes much easier to close the game earlier.

Choose your games wisely before bed

If you absolutely must play something in the evening, opt for lower intensity, single player experiences instead of competitive PvP matches. Avoid games that require fast reaction times, strategic planning under pressure, or high emotional investment.

The bigger picture: sleep as a performance tool

If you’re an athlete, gym goer, or someone who trains regularly, sleep isn’t just about feeling rested. It’s a recovery tool that directly impacts your performance, injury risk, and long term progress.

Research shows that athletes who average less than eight hours of sleep are 1.7 times more likely to suffer injuries during the season. Sleep deprived athletes also show approximately 20 percent slower reaction times, reduced strength output, and impaired motor learning.

Every hour of lost sleep is an hour your body can’t repair muscle tissue, consolidate motor skills, or regulate stress hormones. And if late night gaming is consistently cutting into your sleep, you’re leaving gains on the table.

Final thoughts: balance gaming and recovery

Competitive PvP gaming is fun, social, and mentally engaging. But when it comes at the expense of quality sleep, it undermines your health, performance, and overall well being.

The science is clear: gaming before bed elevates heart rate, suppresses melatonin, disrupts circadian rhythms, and reduces the quality of your sleep. Even a short 30 minute session can have measurable effects, especially if you’re playing high intensity, competitive games.

The good news? Small changes make a big difference. Finish your last match 60 to 90 minutes before bed, use blue light filters, dim your lights, and replace post game scrolling with a calming wind down routine. Track your sleep data to see the impact, and adjust your habits accordingly.

Your next PR, your injury prevention, and your long term health all depend on quality sleep. Protect it.

You have booked the flight and packed your gear. You are ready to compete or train in a new location. But there is one opponent you cannot outrun with speed or strength alone. It is biology.

Crossing multiple time zones does more than make you feel groggy. It fundamentally disconnects your internal biological clock from the world around you. For an athlete, this is not just an inconvenience. It is a performance liability.

Your body runs on a strict schedule known as the circadian rhythm. This internal clock controls hormone release, digestion, body temperature, and muscle repair. When you travel across the world, you force your body to perform when it thinks it should be asleep. You also ask it to sleep when it is primed to be awake.

The result is a physiological state that mimics intoxication. Your reaction times slow down. Your coordination drops. Your risk of injury spikes. If you are serious about your performance, you need to treat travel recovery with the same discipline you apply to your training.

This guide will explain exactly what happens to your body when you travel and how to fix it using data, light, and specific supplements.

The Physiology of Travel Fatigue

Most people think jet lag is just being tired. If that were true, a strong coffee and a nap would fix it. But jet lag is actually a temporary circadian disorder.

Your body loves predictability. It anticipates sunrise and sunset to regulate cortisol and melatonin. When you jump forward or backward by several hours, every system in your body gets confused.

The “clock on the wall” says 8 am, but your “body clock” might believe it is 2 am. This misalignment affects nearly every aspect of your physiology.

Digestion and Metabolism

Your gut has its own clock. It prepares enzymes and acids when it expects food. When you eat a heavy meal at a time your body perceives as biological night, your digestion struggles. This often leads to bloating, discomfort, and poor nutrient absorption.

Body Temperature Regulation

Your core body temperature naturally drops in the evening to facilitate deep sleep. When you travel, this rhythm stays anchored to your home time zone. You might find yourself sweating in bed at your destination because your body thinks it is the middle of the afternoon.

Hormone Chaos

Cortisol is your stress and wakefulness hormone. It usually peaks in the morning to wake you up. Melatonin is your sleep hormone. When these fire at the wrong times, you feel wired and tired simultaneously. You lay awake feeling exhausted but unable to sleep, or you feel ready to collapse during your midday warm up.

What To Expect From Your Wearables

If you track your metrics with an Oura Ring, Whoop, or Garmin, be prepared for some ugly numbers. Travel places a massive strain on the autonomic nervous system. Seeing the data dip can be discouraging, but understanding it gives you power.

Your Sleep Score Will Plummet

Data from hundreds of thousands of Oura members shows significant declines on travel days. On average, you can expect to lose over 30 minutes of total sleep duration. Your Sleep Score will likely drop by 5 points or more. This is normal. Do not panic.

Deep and REM Sleep Take a Hit

Your sleep architecture changes. You will likely see a reduction in both Deep and REM sleep stages. This matters because Deep sleep is for physical repair, while REM is for mental focus and skill consolidation. A drop here means you recover slower and your technical skills might feel “rusty” the next day.

Heart Rate Variability (HRV) and Resting Heart Rate (RHR)

Travel stress activates your sympathetic nervous system (fight or flight). You will typically see your HRV drop significantly. Oura data suggests an average drop of 0.15 ms, but for many athletes, it is much more severe. Your Resting Heart Rate will likely climb by at least 1 beat per minute, often more, as your body works overtime to maintain homeostasis in a pressurized cabin and a new environment.

Symptom Radar Activity

If you use Oura, the Symptom Radar might flag you. This feature detects deviations in your biometric trends. Because your body temperature regulation is out of sync, you might run hotter than usual during the night. The radar might interpret this as the onset of sickness. In this context, it is often just circadian confusion.

The Strategy: Before You Fly

Recovery starts before you board the plane. You can reduce the shock to your system by preparing your body for the shift.

Shift Your Schedule

If you are traveling East, try to wake up and go to bed 30 to 60 minutes earlier each day for three days before departure. If you are traveling West, do the opposite. Delay your sleep and wake times by an hour each day.

Bank Sleep

Sleep debt is real. Go into your trip well rested. Aim for an extra 30 to 60 minutes of time in bed for the week leading up to your trip. A well rested body handles stress better than a deprived one.

The Strategy: In The Air

The environment inside a plane is harsh. It is dry, loud, and pressurized.

Set Your Watch Immediately

As soon as you sit down, change your watch to the time at your destination. Mentally start living in that time zone. If it is day time where you are going, stay awake. If it is night time, put on an eye mask and try to sleep.

Fast or Eat Light

Heavy meals on planes are a bad idea. Your digestion is already compromised by the altitude and lack of movement. Stick to light snacks or fast entirely until breakfast time at your destination. This helps reset your metabolic clock.

Hydrate Aggressively

Airplane cabins have incredibly low humidity. Dehydration thickens your blood and makes your heart work harder, worsening your recovery score. Drink water constantly. Avoid alcohol and excessive caffeine.

The Strategy: On The Ground

Once you land, your primary goal is to anchor your body to the new time zone.

Light is King

Light is the most powerful signal for your circadian rhythm. You need to use it strategically.

For Eastward Travel (e.g. Auckland to Los Angeles):
You need to advance your clock. Seek out bright morning light as soon as you wake up. This pulls your rhythm earlier. Avoid bright light in the late afternoon and evening, as this will push your rhythm later and make it harder to fall asleep.

For Westward Travel (e.g. Auckland to London):
You need to delay your clock. You want light in the late afternoon and early evening. This signals to your body that the day is not over yet.

Move Your Body

Exercise is another powerful time giver. A light workout or a run in the fresh air helps reset your peripheral clocks (like those in your muscles). Keep the intensity low for the first day. Your coordination is compromised, so heavy lifting or technical drills can wait.

The Supplement Protocol

Supplements are tools, not magic wands. When used correctly, they can accelerate your adjustment. Always consult with a medical professional before starting a new supplement routine.

Melatonin

This is the most famous jet lag tool, but most people use it wrong.
The Dose: Less is more. You only need 0.5 mg to 1 mg. Large doses (5 mg or 10 mg) can leave you groggy the next day.
The Timing: Take it 30 to 60 minutes before your target bedtime in the new time zone. This signals to your brain that it is time to wind down.

Magnesium Glycinate

Magnesium is essential for relaxation and nervous system regulation. The “glycinate” form is particularly good for sleep because it is gentle on the stomach and highly absorbable.
The Strategy: Take 200 mg to 400 mg with your evening meal or before bed to help relax your muscles and calm your nervous system.

Glycine

Glycine is an amino acid that helps lower core body temperature. Since temperature regulation is a major issue with jet lag, this is a powerful tool.
The Evidence: A study published in Frontiers in Neurology found that 3 grams of glycine taken before bed improved sleep quality and reduced fatigue the next day, even when sleep was restricted.
The Strategy: Mix 3 grams of glycine powder into water or herbal tea before bed.

B Vitamins

B Vitamins are crucial for energy production. They help convert food into fuel.
The Strategy: Take a high quality B Complex in the morning. This supports energy levels during the day and helps combat that daytime grogginess.

Taurine

Taurine is an amino acid that supports GABA activity in the brain. GABA is a neurotransmitter that promotes calmness.
The Strategy: Taurine can be helpful in the evening to wind down, or during the day to support cellular hydration and calmness without sedation.

Acetyl L Carnitine

This amino acid supports mitochondrial function and energy production.
The Strategy: Take it in the morning to support mental clarity and focus when you are fighting through brain fog.

Accelerating Recovery

You have landed. You are following the light protocols. You are taking your supplements. How do you recover as fast as possible?

The Power Nap Rule

If you are exhausted during the day, you can nap. But you must be strict. Set an alarm for 20 minutes.
If you sleep longer than 20 minutes, you risk entering deep sleep. Waking up from deep sleep leaves you with “sleep inertia,” making you feel worse than before. Long naps also reduce your “sleep pressure,” making it harder to fall asleep at night.

Create a Sleep Sanctuary

Your hotel room needs to be a cave.
Dark: Use an eye mask or clip the curtains shut. Even a tiny sliver of street light can suppress melatonin.
Cool: Set the thermostat between 18 and 20 degrees Celsius. This mimics the natural temperature drop your body needs for sleep.
Quiet: Use earplugs or a white noise app to block out unfamiliar city sounds.

Be Patient With Your Performance

Do not expect a Personal Best on day one. Your body is allocating resources to realignment, not peak force production.
Give yourself 2 to 3 days of lighter training. Focus on mobility, technique, and aerobic work. Once your Sleep Score stabilizes and your Resting Heart Rate returns to baseline, you are cleared for maximum effort.

Conclusion: Own Your Recovery

Travel is a stressor, but it does not have to be a barrier. By understanding the biology of your circadian rhythm, you can mitigate the damage.

You monitor your training load. You weigh your food. You track your sets and reps. Why would you leave your sleep to chance?

Plan your travel protocol. Pack your sleep kit. Respect the biology. If you control the variables you can control, you will be ready to perform when it counts.

The difference between a sluggish session and a great performance often comes down to how well you slept three nights ago. Do the work in the dark so you can shine in the light.

Your body keeps receipts. 🧾

Every late night email you answered. Every extra shot of espresso. That heavy squat session from Tuesday. The glass of wine you had to wind down.

You might feel fine when the alarm goes off. You might tell yourself you are ready to crush the day. But your biology does not lie.

For years, athletes relied on “feel” to gauge recovery. If you were not sore, you trained hard. If you were tired, you drank more coffee. But in the age of wearable tech, we have moved past guessing. We now have a dashboard for our nervous system.

When your Oura ring or Whoop strap flashes a readiness score of 85 or higher, it is doing more than giving you a gold star. It is giving you physiological permission to push your limits.

But what exactly goes into that number? Why does 85 seem to be the magic threshold for peak performance? And how can you reliably hit that green zone when life gets busy?

Let us decode the data behind your daily score and look at why hitting 85+ is the secret weapon for your next PR. 🚀

Decoding the magic number 85

It is easy to become obsessed with the single number on your screen. You wake up, check the app, and let it dictate your mood. But to truly use this tool, you need to understand what is happening under the hood.

A readiness score (or recovery score, depending on your device) is not a random calculation. It is an aggregate of several biomarkers that indicate how much stress your body is currently handling.

When that score hits 85, it is a signal that your autonomic nervous system is balanced. You are not in “fight or flight” mode (sympathetic dominance). You are in “rest and digest” mode (parasympathetic dominance).

Here are the key pillars that build that score.

Heart Rate Variability (The hero metric)

If there is one metric that matters most for the athletic population, it is Heart Rate Variability (HRV).

Many people assume a steady heart rate is good. Paradoxically, you want your heart rate to be highly variable when you are at rest.

Your heart should not beat like a metronome. It should react instantly to your needs. If you inhale, it speeds up slightly. If you exhale, it slows down. This “variability” shows that your nervous system is responsive and agile.

A high HRV indicates that your body is recovered and ready to handle stress. A low HRV suggests your body is still fighting yesterday’s battles, whether that is a tough workout, a viral infection, or just general life stress.

When you see that readiness score climb above 85, it is almost always driven by a spike in your HRV. It means your tank is full. 🔋

Resting Heart Rate (The efficiency engine)

While you want high variability, you want a low baseline speed.

Your Resting Heart Rate (RHR) is the number of times your heart beats per minute when you are fully relaxed. For athletes, a lower RHR is a badge of honour. It signifies a strong heart muscle and efficient cardiovascular system.

When your RHR dips below your personal average, your readiness score climbs. It means your heart does not have to work as hard to maintain basic bodily functions. It has spare capacity.

Conversely, if you wake up and your RHR is five beats higher than normal, your readiness score will tank. This is often the first sign of overtraining or pending illness.

Sleep Balance (The foundation)

You cannot hack biology. If you do not sleep, you do not recover.

Most wearables track two things here: sleep duration and sleep quality.

Duration is simple math. Did you get enough hours? But quality is where the magic happens. Your device looks for Deep Sleep (physical repair) and REM sleep (mental repair).

An 85+ readiness score rarely happens after a restless night. It requires consistent, quality sleep where your body completes its full cycles of repair.

Body Temperature (The subtle signal)

This is the metric most people ignore until it is too late.

Your body temperature should remain stable during the night. If your skin temperature deviates from your baseline, even by half a degree, it alerts your algorithm.

A spike in temperature often means your body is fighting something. It could be a virus. It could be inflammation from injury. It could be the metabolic heat produced by digesting a late meal or processing alcohol.

When your temperature stays flat and stable, your readiness score goes green.

The 2025 NCAA Study connection 🏀

You might think these numbers are just interesting data points. But they translate directly to performance on the court and in the gym.

The link between high readiness scores and athletic output is becoming undeniable.

In a 2025 NCAA study, researchers tracked collegiate basketball players to see if their morning data predicted their evening game performance. The results were telling.

Hoopers who woke up with higher readiness scores (specifically in that optimal zone) and fewer sleep disturbances racked up more points per game.

But it was not just about energy. It was about precision.

The study showed sharper shooting percentages in athletes with high readiness. This makes perfect physiological sense. When your nervous system is primed (high HRV) and your brain is rested (sufficient REM sleep), your motor learning and reaction times are optimised.

You see the ball clearer. Your decision making is faster. Your mechanics are fluid.

Conversely, players with low readiness scores showed slower reaction times and “foggy” proprioception. They were working harder to achieve less.

This study validates what we have known intuitively: You cannot out train a bad recovery score.

What a green score actually feels like

Data is great. But as an athlete, you need to connect the data to how you feel.

When you wake up with an 85+ score, pay attention to your body before you even look at your phone.

You likely feel a sense of calm energy. It is not the jittery energy of caffeine. It is a deep, sustainable reservoir of power.

Mental clarity: You are less likely to experience brain fog. Tasks that usually feel annoying might feel effortless.

Motivation: Your perceived exertion is lower. The idea of going to the gym feels exciting rather than like a chore.

Physical looseness: You might notice less stiffness in your joints. Your DOMS (delayed onset muscle soreness) might be significantly reduced.

This is your body giving you the green light. 🚦

How to train based on your score

So you have your score. Now what?

The smartest athletes do not just track data. They use it to adjust their programming. Here is a simple framework for autoregulation based on your readiness.

The Green Zone (85 plus)

Status: Primed.
Strategy: Push.

This is the day to chase that PR. Your nervous system is ready to recruit maximum motor units.

  • Attempt a 1 Rep Max.
  • Do high intensity interval training.
  • Tackle the most complex skill work in your sport.
  • Add volume to your accessories.

If you have a heavy leg day scheduled but you wake up “Green,” you have permission to add weight to the bar. Your risk of injury is lower, and your potential for adaptation is higher.

The Yellow Zone (70 to 84)

Status: Baseline.
Strategy: Maintain.

This is where you will live most of the time. You are recovered enough to train, but you are not superhuman.

  • Stick to the program as written.
  • Focus on technique and volume rather than max intensity.
  • Do steady state cardio.

You do not need to back off, but you should not expect to feel invincible. Listen to your body during warm ups.

The Red Zone (Under 70)

Status: Strained.
Strategy: Recover.

Your body is waving a red flag. 🚩

Ignore this, and you risk injury or burnout. This does not mean you have to sit on the couch (unless you are sick), but you need to adjust the intensity.

  • Focus on active recovery (walking, mobility).
  • Keep heart rate in Zone 2.
  • Prioritise sleep and nutrition over training volume.

If you had a heavy squat session planned, maybe swap it for technique work or a lighter variation. The goal today is not to break the body down further. It is to help it bounce back.

Practical ways to boost your score 📈

You are not helpless against the algorithm. You can actively influence your readiness score with a few science backed habits.

If you want to see more 85s on your dashboard, try these protocols.

1. The 3 2 1 Dinner Blueprint

Food is fuel, but timing is everything. Eating a heavy meal right before bed forces your body to focus on digestion rather than recovery. This raises your heart rate and body temperature, tanking your score.

Try the 3 2 1 rule:

  • 3 hours before bed: Finish your last large meal.
  • 2 hours before bed: Stop drinking alcohol (it destroys REM sleep).
  • 1 hour before bed: No screens.

For your dinner plate, aim for balance to keep blood sugar stable. Half veggies, one quarter slow carbs (like kumara or rice), and one quarter lean protein.

2. Temperature control

Your body needs to drop its core temperature by about 1 degree Celsius to initiate sleep and enter deep recovery phases.

If your room is too hot, your heart has to pump blood to your skin to cool you down. This keeps your heart rate elevated all night.

Keep your room cool (around 18 degrees Celsius is ideal). If you are an athlete carrying a lot of muscle mass, you generate more heat. Consider breathable bedding or a mattress designed for cooling to stop you from overheating.

3. Light discipline

Your circadian rhythm is ruled by light.

Get sunlight in your eyes within 30 minutes of waking up. This anchors your cortisol peak to the morning, where it belongs.

Then, eliminate blue light at night. Blue light suppresses melatonin, the hormone that signals to your body that it is time to wind down.

4. Alcohol awareness

We hate to be the bearer of bad news. But alcohol is the quickest way to ruin your readiness score.

Even one drink can crush your HRV and spike your RHR. It acts as a sedative, knocking you out, but it fragments your sleep quality.

If you want an 85+ score for a big training session or game, save the drink for another night.

Your personal dashboard

Your readiness score is not a judgment on your character. It is a tool.

It is there to help you make smarter decisions. It gives you permission to rest when you need it and the confidence to push when you are ready.

When you stop fighting your physiology and start working with it, everything gets easier. Your mood stabilises. Your energy becomes consistent. And yes, your gym performance goes through the roof.

So check your wrist.

Green score? Lace up. Smash training. 👟🔥

Yellow score? Stay consistent.

Red score? Prioritise rest.

Your body is always talking to you. It is time to start listening.
