How much sleep is enough?
Sleep requirements differ from one person to the next depending on age, physical activity levels, general health and other individual factors. In general:
* Primary school children – need about nine to 10 hours. Studies show that increasing your child’s sleep by as little as half an hour can dramatically improve school performance.
* Teenagers – need about nine to 10 hours too. Teenagers have an increased sleep requirement at the time when social engagements and peer pressure cause a reduction in sleep time. Lifestyle factors such as early school start times deprive them of the required sleep-in. There is evidence that around the time of becoming a teenager, there is a shift in the sleep–wake cycle to being sleepy later in the evening with a preference for waking later.
* Adults – need about eight hours, depending on individual factors. We tend to need less sleep as we age, but be guided by your own state of alertness – if you feel tired during the day, aim to get more sleep.
Sleep suggestions
Suggestions on how to get more sleep include:
* Purposefully go to bed earlier each night.
* Don’t smoke or drink alcoholic or caffeinated beverages in the hours before bedtime.
* Improve your sleeping environment in any way you can – for example, keep it dark and sound-proof, turn off lights and wear earplugs if you have noisy neighbours.
* Don’t have any distractions in the bedroom such as TV or a computer.
* Use relaxation techniques to help you fall asleep quickly.
* Seek professional assistance for sleep disorders such as snoring.
* Browse through the Better Health Channel fact sheets on sleep to find ways to improve sleeping habits for you and your baby or child.
Where to get help
* Your doctor
* Sleep disorder clinic
Things to remember
* Not enough sleep or disruptions to the sleep–wake cycle (such as those that may occur with shift work or travelling to a different time zone) cause the physiological state known as fatigue.
* Staying awake for 24 hours leads to a reduced hand-to-eye coordination that is similar to having a blood alcohol content of 0.1.
* Sleep deprivation affects children in different ways to adults – sleepy children tend to ‘rev up’ rather than slow down.
