Sleep Hygiene: A Practical Guide for Better Rest
By MindWell Team · 3/12/2026 · 4 min read
Sleep is a biological necessity. The National Sleep Foundation recommends 7–9 hours of sleep per night for adults, yet many people consistently fall short. Poor sleep is closely linked with increased anxiety, depression, irritability, impaired decision-making, and reduced immune function.
The good news: many sleep problems respond well to behavioural changes — collectively known as sleep hygiene.
What Is Sleep Hygiene?
Sleep hygiene refers to a set of habits and practices that support consistent, quality sleep. Unlike sleep medications, these habits address the underlying behavioural and environmental factors that disrupt rest.
Core Sleep Hygiene Practices
1. Keep a Consistent Schedule
Going to bed and waking at the same time every day — including weekends — anchors your body's circadian rhythm. Irregular schedules confuse the internal clock and reduce sleep quality.
Tip: Choose a realistic wake time and work backwards from it. If you need to wake at 6:30 am and require 8 hours, aim to be asleep by 10:30 pm.
2. Create a Wind-Down Routine
Your brain needs a transition from wakefulness to sleep. Spend the last 30–60 minutes before bed doing low-stimulation activities:
- Reading a physical book
- Light stretching or gentle yoga
- A warm shower or bath (the subsequent drop in body temperature promotes sleepiness)
- Journalling to offload the day's thoughts
3. Limit Screen Time Before Bed
Smartphones, tablets, and computers emit blue light, which suppresses melatonin production — the hormone that signals sleep onset. The content itself (news, social media) also tends to be mentally stimulating.
Try: Setting a "no screens" rule 30–60 minutes before bed, or using blue-light filtering apps if screens are unavoidable.
4. Optimise Your Sleep Environment
The ideal sleep environment is:
- Cool – most people sleep best between 16–19°C (60–67°F)
- Dark – even small amounts of light can disrupt sleep cycles. Blackout curtains help.
- Quiet – use earplugs or a white noise machine if needed.
5. Limit Caffeine and Alcohol
- Caffeine has a half-life of about 5–7 hours. Drinking coffee at 3 pm means half of it is still in your system at 8 pm.
- Alcohol may help you fall asleep faster but fragments sleep architecture and suppresses REM sleep, leaving you less rested.
General guidance: Avoid caffeine after midday and alcohol within 2–3 hours of bedtime.
6. Reserve Bed for Sleep (and Sex)
Using your bed for working, watching TV, or scrolling creates a mental association between the bed and wakefulness. If you cannot sleep after about 20 minutes, get up, go to another room, and do something calm until sleepy.
7. Get Morning Light Exposure
Natural light in the morning helps reset your circadian clock. Try to get at least 10–15 minutes of natural light within an hour of waking — even on cloudy days.
8. Manage Worry Before Bed
Pre-sleep worry is one of the most common sleep disruptors. Keeping a notebook by your bed to write down tomorrow's concerns ("brain dump") or practising 5–10 minutes of slow breathing can help quiet the mind.
Conditions That May Need Professional Assessment
Sleep hygiene is highly effective for behavioural sleep problems. However, some conditions require professional assessment:
- Insomnia disorder – persistent difficulty falling or staying asleep despite good sleep hygiene
- Sleep apnoea – breathing interruptions during sleep (often associated with snoring and daytime fatigue)
- Restless legs syndrome – uncomfortable sensations in the legs at night
If you have tried sleep hygiene for several weeks without improvement, or if you feel excessively sleepy during the day despite adequate time in bed, please speak with a healthcare professional.
Cognitive Behavioural Therapy for Insomnia (CBT-I)
CBT-I is considered the first-line treatment for chronic insomnia by the American College of Physicians and other major clinical bodies. It combines sleep hygiene with sleep restriction, stimulus control, and cognitive techniques. It is more effective and more durable than sleep medication for most adults.
Ask a mental health professional or GP about CBT-I if insomnia persists.
Summary
Consistent sleep schedule, a calming wind-down routine, a dark and cool environment, limiting caffeine and screens, and managing pre-sleep worry are the core pillars of sleep hygiene. Small changes, applied consistently, produce meaningful improvements over weeks.
