Why is sleep important?

Sleep is not just resting or taking a break from busy routines. Sleep is a key part of good health. Getting enough sleep may help the body recover from illness and injury. Not getting enough sleep over a period of time is linked to health problems. They include obesity, diabetes, and heart disease.

The mental benefits of sleep are also important. Sleep problems can make daily life feel more stressful and less productive. Some people with chronic trouble sleeping (insomnia) are more likely to have mental health problems. Sleep problems are also tied to depression. In a research survey, people who had trouble getting enough sleep had trouble doing tasks that use memory and learning.

How much sleep do you need?

Sleep needs vary from person to person. But most healthy adults need about 7 to 9 hours of sleep a night. You may need more or better sleep if you:

  • Have trouble staying alert during quiet activities

  • Are irritable with coworkers, family, or friends

  • Have trouble focusing or remembering facts

  • Have trouble falling asleep or staying asleep, or wake up early and can't get back to sleep
