Rest and sleep

Sleep is one of the most powerful tools we have for feeling well, yet it's often the first thing we sacrifice when life gets busy. Healthdirect describes sleep as an essential function, just like air, water and food, and important for both physical and emotional wellbeing. When we don't get enough, we notice it in our mood, energy, concentration and patience.

Rest matters too. Not every moment of rest needs to be sleep. Short breaks during the day, quiet evenings and genuinely restful weekends all help us recharge. This section explains how much sleep adults need, the habits that make good sleep more likely and how to build more rest into your days.

How much sleep?

Most adults need about 7 to 9 hours of sleep a night to feel refreshed and function at their best the next day, according to healthdirect and the Sleep Health Foundation. Australia's 24-hour movement guidelines also recommend 7 to 9 hours of good quality sleep for adults, with consistent bed and wake-up times. Individual needs vary, so pay attention to how you feel during the day.

Habits matter

You can't force yourself to fall asleep, but you can make it more likely. Healthdirect describes sleep hygiene as a set of habits and environmental factors you can change. Key habits include going to bed and waking up at around the same time each day, keeping your bedroom quiet, dark and comfortable, limiting caffeine later in the day, avoiding screens before bed and getting regular exercise. Our better sleep habits guide explains each one.

Winding down

Many people struggle to sleep not because they aren't tired, but because their mind is still racing. A consistent wind-down routine in the hour before bed can help signal to your body that it's time to rest. That might include dimming the lights, putting devices away, a warm shower, reading or a relaxation exercise. Healthdirect also suggests dealing with worries earlier in the day rather than at bedtime.

Rest during the day

Good rest isn't only about nights. Short breaks during the working day, time away from screens, a few minutes of slow breathing or a walk outside can all help you recharge. If you need a nap, healthdirect suggests keeping it to about 20 minutes. Our naps and daytime rest guide has more ideas.

Sleep and stress

Sleep and stress are closely linked. Stress can make it harder to fall asleep and stay asleep, and poor sleep can make stress harder to manage. Relaxation techniques, such as slow breathing and progressive muscle relaxation, can help on both fronts. Healthdirect lists relaxation techniques among the approaches that can help with insomnia. See our stress and calm section.

When to get help

Occasional poor sleep is normal. But if sleep problems persist, affect how you function during the day or come with symptoms such as loud snoring, gasping or pauses in breathing during sleep, talk to your doctor. Insomnia and other sleep disorders are common and treatable. Healthdirect notes that treatments for insomnia include improving sleep habits, relaxation techniques, cognitive behaviour therapy and, in some cases, medicines.

Never drive or operate machinery if you feel drowsy. Healthdirect notes that lack of sleep impairs reaction times, which makes driving very dangerous.

A simple sleep check-in

Every few weeks, ask yourself a few questions. Am I going to bed and waking up at roughly the same times? Do I feel reasonably refreshed most mornings? Am I relying on caffeine to get through the afternoon? Is my bedroom dark, quiet and free of screens? Am I making time to wind down in the evening? Your answers can point to one or two habits worth adjusting. Small, steady changes tend to last longer than an overnight overhaul, and a short sleep diary can help you see whether they are working.

Sleep across life stages

Sleep changes over a lifetime. Healthdirect notes that children and teenagers need more sleep than adults, that sleep needs stabilise at around 20 years old, and that older people often sleep more lightly but usually need about the same amount as in younger adult life. Pregnancy, new parenthood, menopause, shift work and caring responsibilities can all disrupt sleep. If your circumstances make good sleep hard, focus on what you can control and talk to your doctor about extra support.
