Sleep hygiene is the collection of daily habits and environmental conditions that influence how well you sleep. Small, consistent changes to your routine can make a meaningful difference to how quickly you fall asleep, how deeply you sleep, and how rested you feel in the morning. Use our free sleep calculator to plan your ideal bedtime around your wake-up time and natural sleep cycles.
1. Keep a consistent wake time
Going to bed and waking at the same time every day — including weekends — is one of the most consistently recommended sleep-hygiene habits in research. Your circadian rhythm (the internal clock that governs sleep-wake cycles) is set largely by light and regular timing. A stable wake time anchors your internal clock more reliably than any other single habit. Sleeping in significantly on weekends can shift your rhythm and make Sunday nights harder.
2. Get morning light exposure
Bright light in the morning — ideally natural daylight — is a strong circadian signal that tells your body it is time to be awake and alert. It also helps set the countdown for melatonin release later in the evening. Even 10–20 minutes outdoors after waking, or sitting near a bright window, may support your body clock. On overcast days or in winter, some people find a dedicated light therapy lamp helpful.
3. Limit caffeine in the afternoon and evening
Caffeine has a half-life of roughly five to seven hours in most adults, meaning that an afternoon coffee may still have a noticeable effect on your system by bedtime. Sensitivity varies widely between individuals, but a common guideline is to avoid caffeine after early-to-mid afternoon. Tea, cola, and certain energy drinks also contain caffeine and are worth considering alongside coffee.
4. Build a wind-down routine
Your nervous system does not switch instantly from an active, alert state to one ready for sleep. A consistent pre-sleep routine — ideally 30 to 60 minutes before bed — signals to your body that sleep is approaching. This might include dimming lights, a warm shower or bath, light reading, or gentle stretching. The specific activities matter less than the consistency of the cue.
5. Keep your bedroom cool and dark
Core body temperature naturally drops as you fall asleep. A cooler room (often cited in the range of 16–19°C / 60–67°F, though comfort varies) supports this process. Darkness is equally important: even low levels of light can interfere with melatonin production. Blackout curtains, an eye mask, or covering standby lights can help create a more sleep-supportive environment.
6. Reduce screen exposure before bed
Screens emit blue-spectrum light that can suppress melatonin and signal wakefulness to the brain. Reducing screen use in the 30–60 minutes before bed — or using night-mode / warm-spectrum settings — may help. Beyond the light itself, the mentally stimulating or emotionally activating nature of news, social media, and videos can make it harder to wind down regardless of screen brightness.
7. Avoid large meals close to bedtime
Eating a heavy meal within two to three hours of bed can interfere with sleep comfort, particularly for people prone to indigestion or acid reflux. A light snack is generally fine for most people. Alcohol is also worth noting: while it may initially feel sedating, it tends to fragment sleep in the second half of the night and reduces REM sleep.
8. Exercise regularly — but mind the timing
Regular physical activity is associated with better sleep quality across many studies. It can help reduce stress hormones, lower the time it takes to fall asleep, and increase time in deep sleep. For most people, exercise earlier in the day or in the afternoon is more supportive of sleep than vigorous activity in the two hours before bed, which can be stimulating. That said, individual responses vary — some people sleep fine after evening exercise.
9. Manage stress and try brief mindfulness
A mind still processing worry or unresolved tension at bedtime is one of the most common barriers to falling asleep. Practical approaches include writing down tomorrow's tasks before bed (offloading the mental list), brief breathing exercises, or a short body-scan meditation. These do not need to be elaborate — even five minutes of intentional slowing-down can shift the nervous system toward a more restful state.
10. Get out of bed if you can’t sleep
If you have been lying awake for 20 minutes or more, most sleep specialists suggest getting up and doing something calm in dim light until you feel sleepy again. Staying in bed while awake and frustrated can inadvertently train your brain to associate the bed with wakefulness. Keeping the bed associated only with sleep (and intimacy) strengthens the mental link between the bed and sleep.
Putting it together
You do not need to implement all ten habits at once. Choosing one or two — particularly a consistent wake time and a wind-down routine — and practising them for two to four weeks is often more effective than attempting a complete overnight overhaul. Use our sleep calculator to set a realistic bedtime that works with your schedule and natural sleep-cycle length.
