Sleep is more than a period of rest. It is an essential biological function that supports physical recovery, brain function and emotional wellbeing. During sleep, the body carries out processes involved in memory, immune function, hormonal regulation and recovery.
Sleeping for enough hours matters, but duration is only one part of the picture. Sleep quality also depends on how continuous your sleep is, how regularly you sleep and whether you move through the different stages of the sleep cycle.
For people living with sleep-related breathing disorders such as sleep apnea, nighttime sleep can be disrupted repeatedly. Understanding what supports healthy sleep can therefore be useful alongside any treatment prescribed by a healthcare professional.
What happens when you do not get enough sleep?
Insufficient sleep can affect both the body and the brain. In the short term, poor sleep may contribute to tiredness, reduced concentration, slower reactions and difficulties with memory or decision-making.
Persistent sleep deprivation is also associated with a higher risk of several health problems, including cardiovascular and metabolic conditions and mood disorders. Daytime sleepiness can also increase the risk of accidents, particularly when driving or operating machinery.
Sleep quality can be affected by many factors, including lifestyle, the sleep environment and underlying sleep disorders. If sleep problems are persistent or accompanied by symptoms such as loud snoring, breathing pauses during sleep or excessive daytime sleepiness, discussing them with a healthcare professional can help identify the appropriate next steps.
What is sleep hygiene?
Sleep hygiene refers to the everyday habits and environmental conditions that can support healthy sleep. It includes maintaining regular sleep times, creating a comfortable bedroom environment and paying attention to factors such as caffeine, alcohol, physical activity and evening screen use.
Good sleep habits are not about following a perfect routine. Consistency tends to be more useful than making occasional major changes.
Limit screen exposure before bedtime
Phones, tablets, computers and televisions can make it harder to wind down before bed. Light exposure in the evening can influence the body's internal clock, while stimulating content, notifications and prolonged screen use can also keep the mind active.
Try putting screens aside before bedtime and replacing them with a quieter activity, such as reading, listening to calm music or practising a relaxation technique.
Watch your caffeine intake
Caffeine is a stimulant found in coffee, tea, energy drinks, cola, chocolate and some medicines. Because its effects can last for several hours, consuming caffeine later in the day may make it harder to fall asleep or affect sleep continuity.
If you notice that caffeine affects your sleep, consider limiting it during the later part of the day. Individual sensitivity varies, so there is no single cut-off time that works for everyone.
Alcohol and sleep: what is the connection?
Alcohol may make some people feel sleepy initially, but it does not necessarily support good-quality sleep throughout the night. It can alter normal sleep patterns and contribute to nighttime awakenings.
Alcohol can also be particularly relevant for people with sleep apnea. If you have been diagnosed with a sleep-related breathing disorder, discuss alcohol consumption and its potential effects with your healthcare professional.
Stay physically active during the day
Regular physical activity can support healthy sleep and may make it easier to fall asleep. Walking, cycling, swimming and other forms of exercise can be incorporated into a daily routine according to individual circumstances.
For some people, vigorous exercise immediately before bedtime may feel stimulating. If you notice this effect, moving more demanding exercise earlier in the day may make it easier to relax at night.
Create a bedroom that supports sleep
The sleep environment can make a noticeable difference to comfort. A bedroom that is dark, quiet, well ventilated and at a comfortable temperature can help create conditions that are more suitable for sleep.
Your bed and pillow also matter. A pillow that suits your sleeping position and provides appropriate support can contribute to nighttime comfort, particularly for people who use respiratory equipment during sleep.
If you use CPAP equipment, comfort can be especially relevant to your nighttime routine. Explore CPAP pillows and sleep accessories to find products designed around the needs of people using sleep therapy equipment.
Keep a regular sleep schedule
Going to bed and waking up at roughly the same time each day helps maintain a consistent sleep-wake rhythm. Large differences between weekday and weekend schedules can make it harder for some people to maintain their usual routine.
A regular schedule does not mean that every night has to be identical. The aim is to establish a pattern that is realistic and sustainable.
Are naps good for sleep?
A short nap can be useful for some people, but longer or late-afternoon naps may make it harder to fall asleep at night. If you choose to nap, keeping it relatively short and taking it earlier in the afternoon may reduce this effect.
If you regularly need long naps because of significant daytime sleepiness, it is worth discussing this with a healthcare professional, particularly if your nighttime sleep is also disrupted.
Choose lighter evening meals when needed
A large or heavy meal close to bedtime can cause digestive discomfort and make it harder to settle down. Giving yourself some time between dinner and bedtime may help you feel more comfortable.
There is no single evening meal that guarantees better sleep. A balanced diet and eating habits that suit your individual needs are more useful than relying on specific foods as a sleep remedy.
Sleep quality and sleep apnea
Sleep apnea is a sleep-related breathing disorder in which breathing repeatedly becomes reduced or stops during sleep, depending on the type of apnea. These breathing disturbances can interrupt normal sleep and may prevent a person from feeling rested, even after spending enough time in bed.
Common signs can include loud snoring, witnessed pauses in breathing, waking with a choking or gasping sensation and excessive daytime sleepiness. However, symptoms vary, and only a healthcare professional can assess whether sleep apnea is present.
For people who have been prescribed CPAP therapy, the treatment is part of a broader approach to managing sleep apnea. Good sleep habits and a suitable sleep environment can complement prescribed therapy, but they should not be used as a substitute for it.

A good night's sleep is shaped by several factors: regular routines, a comfortable environment, healthy daily habits and appropriate management of any underlying sleep disorder. Small, consistent changes can help create better conditions for rest, while persistent sleep problems deserve professional attention.
