Why Sleeping Is Essential for Human Biology

Sleep helps our bodies repair and grow. It builds bone and muscle and boosts our immune system. It also controls hormones for growth and affects our hunger and metabolism.

The Centers for Disease Control and Prevention (CDC) says sleep is key for health. They recommend adults get 7 or more hours of sleep each night for the best health.

Adults (18-60 years)	7 or more hours
Adults (61-64 years)	7-9 hours
Older Adults (65 years and over)	7-8 hours

The Science Behind Why 8 Hours Sleep Is Important

The science shows 8 hours of sleep is key. A full sleep cycle lasts 90-120 minutes, with stages of non-REM and REM sleep. Getting 4-6 cycles a night is best for health. Sleeping 8 hours helps most people get these cycles.
