Sleep hygiene: habits that support better rest

Sleep hygiene refers to the habits and environmental factors that influence how well you sleep. When these are aligned, they can support falling asleep more easily, staying asleep through the night and waking feeling more refreshed.1
For most adults, quality sleep typically means around 7–9 hours per night, alongside consistent timing and minimal disruption.2
Why sleep hygiene matters
Sleep is closely linked to both physical and mental wellbeing. Ongoing poor sleep can affect energy, mood, concentration and overall daily functioning.3
A key driver of sleep quality is your circadian rhythm: the body’s internal clock that regulates when you feel alert and when you feel sleepy. When your habits support this rhythm, sleep tends to feel more natural and consistent.4
Habit # 1: Consistency in routines
One of the most effective ways to improve sleep is to keep your sleep and wake times as consistent as possible. Going to bed and waking up at similar times each day helps stabilise your sleep–wake cycle, making it easier to fall asleep and wake naturally over time.2
Large swings in sleep timing, such as staying up much later on weekends, can disrupt this rhythm and make the following days feel more difficult. Even small improvements in consistency can support better sleep quality.5
Habit #2: Preparing your body for sleep
It’s common knowledge that the period leading up to bedtime plays an important role in signalling to your body that it is time to wind down… but this is often easier said than done.
A simple, repeatable routine, such as reading, stretching, or listening to something calming, can help reduce stimulation and ease the transition into sleep. Over time, these cues become associated with sleep, helping your body switch off more easily.6
Habit #3: Customising your environment
The space you sleep in can either support or disrupt rest. A bedroom that is cool, dark and quiet is generally associated with better sleep outcomes.2
Light exposure is particularly important. Reducing light in the evening helps the body produce melatonin, a hormone involved in sleep regulation. Even small sources of light or ongoing noise can interfere with this process, especially over time.6
Habit #4: Daily habits that influence sleep
Sleep quality is shaped by what happens across the entire day, not just at night. Caffeine and smoking, particularly later in the day, can make it harder to fall asleep. Alcohol may initially feel sedating but is known to disrupt sleep later in the night.2,7
Physical activity is generally associated with better sleep, particularly when done consistently. However, intense exercise close to bedtime may be stimulating for some people, so timing can make a difference.8
Light exposure also plays a role. Getting natural light during the day, especially in the morning helps reinforce your circadian rhythm, while reducing exposure to bright or blue light in the evening supports the body’s transition toward sleep.4
Habit #5: Strengthening the link between bed and sleep
Your brain builds associations between environments and behaviours. When your bed is used primarily for sleep, it becomes a stronger cue for rest.
If you are unable to fall asleep, getting up and doing a quiet, low-stimulation activity before returning to bed can help maintain this association. Over time, this can support more consistent sleep patterns.9,10
Habit #6: Managing a busy mind
Racing thoughts and mental load are common barriers to sleep. Creating space earlier in the evening to process tasks or concerns can reduce the likelihood of these thoughts surfacing at bedtime.
Simple strategies such as writing a short to-do list or practising relaxation techniques such as meditation may help ease the transition into sleep and reduce difficulty falling asleep.6,10
Key takeaway
Sleep hygiene is not a single habit, but a pattern of behaviours that support consistent, high-quality rest.
Focusing on regular sleep timing, a predictable wind-down routine, and an environment that supports sleep can make a meaningful difference over time.
