Sleep Hygiene: Practical Habits for Better Sleep, Energy and Nervous System Recovery
What is “Sleep Hygiene”?
Sleep hygiene is the collection of habits, routines and environmental cues that help your body prepare for quality sleep.
It’s the habits, routines, supplements, or things we put into place before we go to bed to support our daily rhythm (and in return, energy, hunger, and more!).
For many people, poor sleep is not just about feeling tired. It can affect mood, cravings, stress tolerance, concentration, blood sugar regulation, recovery, and how resilient your nervous system feels the next day.
The good news? You can work on it and improve. Small, consistent changes can make a meaningful difference over time.
Sleep Is a Nervous System Issue
Sleep is not only about being tired enough to fall asleep.
Your body also needs to feel safe enough to switch off.
You wouldn’t be trying to sleep in the jungle while a tiger is standing there staring you down, would you? This is what your nervous system is doing.
If a lot is going on, running on chronic stress, overstimulation, that “wired but tired” state, and you don’t support your environment, how do you expect to sleep well?
This is why sleep hygiene matters. It gives your body repeated signals that the day is winding down and that it is safe to rest.
Start With Your Wake Time
One of the most useful places to start is your wake time.
A consistent wake time helps anchor your body clock, your circadian rhythm, we like to call it. Even if your bedtime varies slightly, waking at a similar time each day gives your body a stronger rhythm to work with. (Sleep Health Foundation, 2024); (National Heart, Lung, and Blood Institute, 2022).
Let’s call this your body clock baseline. Let’s get this right first.
This does not mean you need to be perfect every day. But if your weekday and weekend wake times are completely different, your body can feel like it is constantly adjusting to a new time zone.
A good first step is to choose a realistic wake time and keep it within a steady window most days.
Get Morning Light Early
Morning light is one of the strongest signals for your circadian rhythm. (National Heart, Lung, and Blood Institute, 2022); (Bryan, 2025).
Getting outside early in the day helps tell your body, “This is daytime.” That signal can support better alertness during the day and better sleepiness later at night.
Daily exposure is good too, and the more moments of sun exposure, the more serotonin you help your body create. You may know this as something associated with mood, but did you know you also need sufficient amounts of it to support sleep?
Serotonin is involved in melatonin production, and melatonin is one of the key signals that help the body prepare for sleep. (National Heart, Lung, and Blood Institute, 2022).
Cloudy days still count. A short walk, breakfast outside, or even sitting near natural light can all be useful starting points.
Use Caffeine Strategically
Caffeine can be a helpful part of the morning, but it can become a problem when it stretches too far into the day.
Some people say, “I can have coffee at 4 pm and still fall asleep.” That might be true, but falling asleep is not the only measure of good sleep. Caffeine may still affect sleep depth, restfulness, or night waking.
The key is getting good amounts of deep sleep; it’s quality over quantity. Well, there’s still some quantity, but you get what I mean.
If you think caffeine is affecting your sleep, try cutting back on 1 cup of coffee or setting a caffeine cutoff around lunchtime/early afternoon. (Sleep Health Foundation, 2024); (Sleep Health Foundation, 2025).
Also, remember that caffeine is not just in coffee. It can be found in black tea, green tea, energy drinks, pre-workout, cola, some soft drinks, chocolate, and certain medications.
Alcohol and Sleep Quality
Alcohol can make you feel sleepy at first, but it often reduces sleep quality later in the night. There’s that quality indicator again! (Sleep Health Foundation, 2024); (Sleep Health Foundation, 2025).
This is why some people fall asleep quickly after drinking, then wake around 2–4 am feeling restless, hot, anxious, thirsty, or wide awake.
Your liver also needs to process the alcohol you consume. So instead of resting and recovering, it’s detoxifying. 2-4 am is a common time for your liver to be at its most active, according to Traditional Chinese Medicine (TCM).
Some tactical hacks for this? Reduce alcohol close to bedtime, or cut back one drink and see how you feel.
Screens, Light and Evening Stimulation
Evening is when your body should start receiving “night-time” signals.
This one is a big deal, and I am writing a book that has a chapter all about this, talk about a deep dive.
Blue lights, phone scrolling, emails, work admin, social media, intense conversations, and stressful content can all keep the brain switched on. Evening light exposure can also affect melatonin and circadian timing. (Sleep Health Foundation, 2024); (Suni, 2023).
Remember the tiger scenario before? In this case, the tiger is your social media or work emails. Limit these to at least 60 minutes before bed.
A few small hacks for reducing screen and evening exposure include:
- Use dimming or warm lights in the evening
- Use night mode on devices, or for desktop, use apps like F.lux
- Set a cut-off for checking work emails
I would recommend just selecting one of these first and seeing how you go.
Create a Sleep-Friendly Bedroom
Your bedroom should make sleep easier and signal to your body that this is a safe place for rest.
To simply it, you can simply remember Cool, Dark, Quiet. While there are some more variables, these generally swing in favour of good sleep. (Sleep Health Foundation, 2024).
- Cool – This means breathable bed sheets and temperature-controlled options during hotter seasons.
- Dark – Coming back to the last point. We want it as dark as possible.
- Quiet – Some external factors are unavoidable; if this is the case, invest in some over-ear noise-cancelling headphones.
Something to also note is that if your bedroom has work paper, clutter, or a television, this will make it harder for your brain to associate your bedroom with rest.
Although it’s not easy for everyone, try ensuring that each room as it’s own purpose. Your bedroom is sleep, your dining room is for eating, and your office to work. I would recommend reading Atomic Habits, where James Clear talks about this concept of “each room, one purpose”, thanks James.
Build a Simple Wind-Down Routine
A wind-down routine does not need to be fancy. It could simply be cherry picking a few things I’ve mentioned, or even just one, and going from there.
A good rule of thumb is aiming for 30-60 minutes before bed to engage in some sort of sleep routine. The core theme will be around gently reducing stimulation.
Some good examples I tell clients, which are generally quite tactical, include:
- Reading – Read 10-15 minutes of a non-fiction book. The key takeaway here is non-fiction. Fiction will provide stimulation so please avoid.
- Light stretching – No, everyone’s piece of cake, but maybe you are neglecting some of that stretching you’ve been told to do? This is a perfect time.
- Calm music – Non-stimulating music, there is loads of calming music on Spotify, or you may even want to look into the concept of Binaural Beats, more on this in a later blog.
- Journaling – Do 5-10 minutes of journaling. This is a great way to reduce the brain “noise” and stop the racing mind (Passionflower is also good for this too!).
- A Warm Tea – Prepare nice, warm, caffeine-free tea, which is a perfect, low-friction option. A lavender, chamomile or lemon balm tea is great for calming the nervous system and preparing it for rest.
These are a couple of great options, pick and choose one or two of these and go from there.
What To Do If You Wake During the Night
Waking during the night can be frustrating, especially when your mind starts calculating how many hours are left before the alarm.
Generally, avoid watching your clock (which can mean looking at your phone). This can increase stress and make it harder to settle.
I do often like to prescribe things like Passionflower for this, but obviously, there can be a multitude of factors that cause you to wake. This is generally best discussed in a consultation to determine the cause.
One thing that can actually help is getting up and doing something quiet and boring in dim light until sleep returns. This can be reading, some deep breathing, or meditation. Avoid stimulation where possible. (Sleep Health Foundation, 2024); (Stanford Sleep Health and Insomnia Program, n.d.).
When To Get Extra Support
Sleep hygiene can be a great starting point, but it is not always the full answer.
If you are dealing with ongoing insomnia, loud snoring, gasping during sleep, restless legs, pain, night sweats, panic-like waking, frequent urination, or severe daytime fatigue, it is worth speaking with a qualified health professional.
Sometimes sleep problems are connected to stress, hormones, blood sugar regulation, nutrient status, alcohol use, medications, sleep apnoea, or other underlying factors.

The Takeaway
Better sleep usually comes from consistent cues and prompts that signal your body that the environment is safe, and there’s no tiger coming to eat you.
Your body responds to rhythm: waking at a similar time, getting morning light, using caffeine wisely, lowering evening stimulation, and creating a bedroom that actually supports rest.
Start with one or two changes. Keep them simple. Repeat them often. Simplicity is key.
FAQ
What is sleep hygiene?
Sleep hygiene refers to the daily habits, routines and sleep environment that support better sleep. This includes your wake time, light exposure, caffeine timing, evening routine, bedroom setup and what you do if you wake during the night.
How long does sleep hygiene take to work?
Some people notice changes within a few nights, while others need a few weeks of consistency. Sleep responds best to repeated cues, so the goal is to build habits you can maintain most days.
What time should I stop drinking caffeine?
If sleep is a problem, a good starting point is to stop caffeine around lunchtime or early afternoon. Some people are more sensitive and may need an earlier cut-off.
Does alcohol affect sleep even if it helps me fall asleep?
Yes. Alcohol may make you feel sleepy initially, but it can reduce sleep quality and increase waking later in the night. This is particularly because your liver is also working to detoxify and process the alcohol, and less on recovering from the day just gone.
Should I avoid screens before bed?
You do not need to be perfect, but reducing screens in the final 30–60 minutes before bed can help lower light exposure and mental stimulation. If you do use devices, dim the screen and avoid stressful or stimulating content.
What should I do if I wake up at 3 am?
Try not to check the time or pick up your phone. Keep lights low and give your body a chance to settle. If you remain wide awake, get up and do something quiet and boring in dim light until you feel sleepy again.
Can morning sunlight help me sleep better at night?
Yes. Morning light helps support your circadian rhythm, which can make it easier for your body to feel alert during the day and sleepy at night.
When should I get professional help for sleep problems?
Seek support if poor sleep is ongoing, affecting your mood or energy, or if you experience loud snoring, gasping, restless legs, severe insomnia, persistent fatigue, or frequent waking that does not improve with basic sleep hygiene.
