What happens to your body when you don't get enough sleep

It’s a fact: Many people in the United States have trouble sleeping.

For good health, experts recommend that most healthy adults sleep between seven and nine hours each night. About one-third of U.S. adults report getting insufficient sleep, meaning fewer than seven hours nightly, according to the Centers for Disease Control and Prevention (CDC).

In the long term, consistent sleep deprivation is linked to a range of health problems, including a higher risk of developing dementia, diabetes, heart disease, and mental health disorders like depression and anxiety.

In the short-term, a lack of sleep can affect everyone a little differently. But here’s what a person can generally expect after one or more nights of poor sleep, along with tips for improving your ability to rest.
