What Is Sleep Health?
Healthy sleep is more than simply spending enough time in bed.
Sleep health means getting enough good-quality sleep at the right time.
Healthy sleep supports brain function, physical health, emotional well-being and daytime alertness. Sleep problems can affect how you concentrate, learn, react and function during the day.
Why Does Sleep Matter?
Sleep supports many important functions throughout the body.
Brain Function
Sleep supports attention, learning, memory and decision-making.
Physical Health
Sleep supports normal physical recovery and overall health.
Mood & Emotions
Healthy sleep supports emotional regulation and daytime well-being.
Daily Performance
Good-quality sleep helps you stay alert and respond effectively.
How Sleep Works
Sleep is an active biological process involving different stages throughout the night.
Light Sleep
The body begins transitioning from wakefulness into sleep.
Stable Sleep
Breathing and heart rate generally slow as sleep becomes deeper.
Deep Sleep
Deep sleep is an important part of physical restoration.
REM Sleep
REM sleep is associated with dreaming and important brain processes.
How Much Sleep Do Adults Need?
Sleep needs vary, but most adults should aim for a consistent amount of quality sleep.
Adults
Experts generally recommend that adults get between 7 and 9 hours of sleep each night.
Quality Matters Too
Sleeping for enough hours does not always mean sleep is restorative. Frequent awakenings, breathing problems or other sleep disorders can reduce sleep quality.
Common Sleep Problems
Sleep difficulties can have different causes and may require different approaches.
Insomnia
Difficulty falling asleep, staying asleep or getting good-quality sleep despite having an opportunity to sleep.

Sleep timing becomes out of sync with the body's internal sleep-wake rhythm.
Narcolepsy
A neurological sleep disorder associated with excessive daytime sleepiness and abnormal sleep-wake regulation.
Restless Legs Syndrome
An urge to move the legs that may become stronger during periods of rest or at night.
Sleep Deprivation
Not getting enough sleep, sleeping at inconsistent times or having poor-quality sleep.

What Can Affect Your Sleep?
Sleep can be influenced by routines, environment, health conditions and changes in your body clock.
Stress & Worry
Stress can make it harder to relax, fall asleep or stay asleep.
Irregular Schedule
Shift work, travel or frequently changing sleep times can disturb the sleep-wake rhythm.
Screen & Light Exposure
Bright light and electronic devices close to bedtime can interfere with a healthy wind-down routine.

Regular daytime physical activity can support healthy sleep.
Manage Evening Screen Use

Sleep Routine Changes
Consistent schedules and healthy sleep habits may be recommended as part of treatment.
PAP Therapy

Oral Devices
Certain people with sleep apnea may benefit from a prescribed oral device.
