Sleep Hygiene Checklist: 20 Tips for Better Sleep

"Sleep hygiene" sounds clinical, but it simply means the habits and environment that support good sleep. Most people have one or two bad habits that quietly sabotage their sleep without realising it. The good news? Small changes can make a big difference — often within just a couple of weeks.

Use this checklist as a practical guide. You don't need to overhaul everything at once. Start with the areas where you know you're weakest, and build from there. Print this page, stick it on your fridge, and work through it over the next few weeks.

Your Sleep Environment

Where you sleep matters as much as how long you sleep. These tips focus on optimising your bedroom for rest.

1. Keep Your Bedroom Cool — 16–18°C Is Ideal

Your body needs to drop its core temperature to initiate sleep. A bedroom that's too warm makes this much harder. Most central heating systems run rooms at 20–22°C, which is too warm for optimal sleep. Consider lowering the thermostat in your bedroom or using a timer to turn heating off before bedtime.

2. Make Your Room as Dark as Possible

Even small amounts of light — a standby light, streetlights through thin curtains, a phone screen — can suppress melatonin production and disrupt sleep. Invest in proper blackout curtains or use a sleep mask. Remove or cover any LED lights in your bedroom.

3. Keep Noise to a Minimum

Consistent background noise (like traffic or a noisy neighbour) is one of the most common sleep disruptors. Earplugs are cheap and effective, or consider a white noise machine that masks sudden noises with a steady, soothing sound.

4. Use Your Bed Only for Sleep (and Intimacy)

This is a core principle of cognitive behavioural therapy for insomnia. When you work, eat, watch telly, or scroll your phone in bed, your brain loses the association between bed and sleep. Keep your bed a dedicated sleep space, and you'll find it easier to fall asleep there.

5. Invest in a Supportive Mattress and Pillows

You spend roughly a third of your life on your mattress. If it's more than 7–8 years old, sagging, or causing you to wake up with aches, it's time for a replacement. The right pillow supports your neck in alignment with your spine — the wrong one can cause headaches and restless nights.

Your Daily Habits

What you do during the day affects how well you sleep at night. These habits build sleep pressure and support your circadian rhythm.

6. Get Morning Sunlight Within 30 Minutes of Waking

Natural light in the morning is the most powerful signal for resetting your circadian rhythm. Even 10–15 minutes of outdoor light helps your body clock stay synchronised. This is especially important in winter, when UK daylight hours are limited.

7. Exercise Regularly — But Not Too Late

Regular physical activity significantly improves sleep quality. Even 20–30 minutes of moderate exercise — walking, cycling, swimming — makes a measurable difference. However, vigorous exercise within 2–3 hours of bedtime can raise your core temperature and make it harder to fall asleep. Morning or early afternoon exercise is ideal.

8. Limit Caffeine After 2pm

Caffeine has a half-life of 5–6 hours, meaning half of that 3pm coffee is still in your system at 9pm. For most people, a caffeine cutoff of early afternoon (2pm) is sufficient to prevent sleep disruption. Remember that caffeine hides in tea, chocolate, energy drinks, and some painkillers too.

9. Be Mindful of Alcohol

A nightcap might help you fall asleep faster, but alcohol is a terrible sleep quality promoter. It suppresses REM sleep, increases nighttime awakenings, and disrupts your sleep architecture. If you drink, try to finish at least 3–4 hours before bed, and limit yourself to 1–2 drinks.

10. Eat Your Last Meal 2–3 Hours Before Bed

Eating a large meal close to bedtime can cause discomfort, indigestion, and heartburn — all of which interfere with sleep. A light snack is fine if you're hungry, but heavy, rich, or spicy foods should be eaten earlier in the evening.

Your Bedtime Routine

A consistent wind-down routine signals to your brain that it's time to sleep. Here are the key elements:

11. Set a Consistent Bedtime and Wake Time — Even Weekends

This is probably the single most important sleep habit. Going to bed and waking up at the same time every day (including weekends) stabilises your circadian rhythm. Sleeping in on weekends creates "social jet lag" that makes Monday mornings harder. Try to keep your wake time within a 30–60 minute window every day.

12. Establish a Wind-Down Routine 60–90 Minutes Before Bed

Your brain needs time to transition from wakefulness to sleep. A consistent sequence of calming activities — dimming lights, reading, stretching, journaling — creates powerful sleep cues. For a detailed routine, see our Perfect Bedtime Routine guide.

13. Put Screens Away 60 Minutes Before Bed

The blue light from phones, tablets, and televisions suppresses melatonin production. But it's not just the light — it's the stimulation. Social media, news, and work emails keep your brain in alert mode. Put your phone on charge in another room if you can't resist the temptation.

14. Avoid Clock-Watching

If you wake up during the night, resist the urge to check the time. Clock-watching triggers anxiety about how much sleep you're losing, which makes it harder to fall back asleep. Turn your clock away from your line of sight, or better yet, don't have a visible clock in your bedroom.

Your Mindset

Sleep is as much a mental state as a physical one. These tips address the psychological side of sleep.

15. Don't Try to Force Sleep

The harder you try to fall asleep, the more awake you become. If you've been lying in bed for 20 minutes without falling asleep, get up. Do something boring in low light — read a dull book, fold laundry — until you feel genuinely sleepy, then go back to bed. This prevents your brain from associating bed with frustrated wakefulness.

16. Write Down Worries Before Bed

Racing thoughts are one of the most common sleep complaints. A 5-minute "brain dump" before your wind-down routine can help. Write down whatever is on your mind — tomorrow's to-do list, worries, unfinished tasks. Getting them out of your head and onto paper stops them from circling when you're trying to sleep.

17. Stop Napping After 3pm — and Keep Naps Short

Naps can be useful, but poorly timed naps steal sleep pressure from the night. If you need to nap, keep it to 20–30 minutes and finish before 3pm. Longer naps or late-afternoon naps will make it harder to fall asleep at bedtime.

When to Seek Help

Sleep hygiene tips work for mild to moderate sleep difficulties, but they're not a substitute for medical advice when you need it.

18. If You've Been Struggling for More Than 4 Weeks, See Your GP

Chronic insomnia (difficulty sleeping 3+ nights per week for 3+ months) often responds well to CBT-I (Cognitive Behavioural Therapy for Insomnia), which is available through the NHS. Your GP can also check for underlying conditions like sleep apnoea, thyroid issues, or vitamin deficiencies that might be contributing to poor sleep.

19. Consider a Sleep Tracker — But Don't Obsess

A sleep tracker can provide useful insights into your sleep patterns — how much deep sleep you're getting, how often you wake, and how your habits affect your sleep. However, don't let the data create anxiety. "Orthosomnia" (stress about perfect sleep data) is a real phenomenon. Use trackers as a general guide, not a strict measurement.

20. Be Patient — Good Sleep Habits Take Time to Build

You won't transform your sleep overnight. Most sleep habits take 2–3 weeks of consistent practice before you notice significant improvements. Don't give up after a few nights if things don't immediately improve. Stick with it, and the results will come.

The Bottom Line

Sleep hygiene isn't about perfection — it's about building habits that support your body's natural need for rest. Start with the 2–3 tips that address your biggest challenges, practice them consistently for a few weeks, and then add more. Small, sustainable changes compound over time into dramatically better sleep.

If you've worked through this checklist and you're still struggling, don't suffer in silence. Speak to your GP — better sleep is worth advocating for.
