About this tool
healthdirect says most adults need about 7 to 9 hours of sleep each night, and the Sleep Health Foundation says most adults need between 7 and 9 hours to feel properly refreshed. Regular bed and wake times help your body clock.
If you often sleep badly, feel unrefreshed, or snore loudly with daytime sleepiness, talk to your GP.
