Quick answer: the most useful sleep-hygiene habits are a consistent wake time, morning daylight, a planned wind-down, less late caffeine and alcohol, regular daytime activity, and a bedroom that is dark, quiet and comfortable. Change one or two habits consistently before trying to change everything at once.
Start here tonight: choose tomorrow’s wake time, stop caffeine at least six hours before bed, dim lights for the final hour, and only go to bed when you feel sleepy.
Sleep hygiene checklist
| Habit | Practical starting point | What to avoid |
|---|---|---|
| Wake time | Get up at roughly the same time every day, including after a poor night | Long lie-ins that shift the next night later |
| Light | Get outdoor daylight earlier in the day; dim indoor light in the final hour | Bright screens immediately before bed |
| Caffeine and alcohol | Test an earlier caffeine cut-off; keep alcohol away from the bedtime routine | Using alcohol as a sleep strategy |
| Wind-down | Repeat a quiet 30–60-minute routine | Work, upsetting news or stimulating tasks in bed |
| Bedroom | Keep it dark, quiet, comfortable and not excessively warm | Using the bed as an office or daytime lounge where possible |
| Movement | Exercise regularly during the day | Very vigorous exercise close to bed if it keeps you alert |
Keep a consistent wake time
The wake time is the most practical anchor because you control it more directly than the moment you fall asleep. Pick a time you can maintain most days. After a poor night, avoid compensating with a long lie-in; the NHS advises returning to regular sleeping hours.
A rigid bedtime can be counterproductive when you are not sleepy. Build the evening around a consistent wake time and a repeatable wind-down, then go to bed when drowsiness arrives.
Use light to mark the start and end of the day
Morning daylight helps reinforce daytime. Open curtains promptly and, where practical, spend time outdoors earlier in the day. In the evening, reduce brightness and move away from highly stimulating screen use before bed.
Night-mode settings may reduce glare, but they do not make late work, scrolling or upsetting content relaxing. The behaviour matters as well as the colour of the screen.
Move caffeine and alcohol earlier
The NHS advises avoiding tea, coffee, alcohol and smoking for at least six hours before bed. People differ, so treat this as a starting experiment: choose a caffeine cut-off, keep it for a week and note whether falling asleep becomes easier.
Alcohol may make someone feel drowsy initially, but it is not a reliable sleep-hygiene tool. It can also interact with medicines and products that cause drowsiness.
Build a repeatable wind-down
A wind-down routine does not need to be elaborate. Choose two or three quiet actions that fit ordinary life:
- lower the lights;
- prepare what you need for the morning;
- take a warm bath or shower;
- read something undemanding;
- listen to calm audio;
- write down tomorrow’s tasks or current worries.

Do not force sleep
The NHS advises that if you cannot sleep, do not try to force it. Get up, sit somewhere comfortable and do something quiet until you feel sleepier, then return to bed. This helps prevent the bed becoming a place associated with frustration and clock-watching.
Avoid repeatedly checking the time. The calculation “if I fall asleep now, I will get…” usually increases pressure without creating sleep.
Make the bedroom easier to sleep in
Dark, quiet and comfortable is the goal. Useful changes may include curtains or blinds, an eye mask, earplugs, addressing an uncomfortable pillow or mattress, and reducing unnecessary heat.
Loud snoring, gasping or breathing pauses are not bedroom-environment problems. They can be signs of sleep apnoea and should be discussed with a GP.
Move during the day
Regular daytime activity supports general health and is part of NHS sleep advice. If vigorous evening exercise leaves you alert, move it earlier. Gentle stretching or an easy walk may fit the wind-down period better.
A simple seven-night experiment
- Choose one consistent wake time.
- Get daylight after waking.
- Use the same caffeine cut-off each day.
- Begin a quiet routine at a set time.
- Only get into bed when sleepy.
- Leave the bed briefly if you are wide awake and frustrated.
- Record only three things each morning: approximate sleep time, wake time and daytime functioning.
This is not a diagnostic sleep diary, but it can show which habits are realistic and what changes when you repeat them.
Where do supplements fit?
Habits come first. A food supplement cannot claim to cure insomnia, produce sleep or replace medical care. Some evening formulas contain nutrients with authorised claims—for example, niacin, vitamin B6 and biotin contribute to normal psychological function and normal functioning of the nervous system. Pantothenic acid contributes to normal mental performance.
If you decide to compare a finished evening formula, you can view the Deepest Sleep ingredient list, directions and cautions.
Those are nutrient claims, not sleep claims. Our ingredient and claims guide explains the distinction. If you are comparing the whole aisle, see UK sleep medicines, herbal remedies and supplements compared.
When should you seek help?
See a GP if changing your sleeping habits has not helped, you have had trouble sleeping for months, or it is affecting daily life. Seek advice if there is loud snoring, gasping, breathing pauses, sudden daytime sleep episodes, persistent low mood, pain, restless legs or another concerning symptom.
