Sleep plays an integral role in health. A good night’s sleep empowers the body to recover and lets you wake up refreshed and ready to take on the day.
Unfortunately, many people have sleep problems and don’t get the rest that they need. Insufficient sleep and poor quality sleep can be due to diverse factors including sleep disorders, medical conditions, and mental health. Sleep issues affect people of all ages, and its impacts can be far-reaching.
While sleep is too complex to sum up with only numbers, reviewing basic facts and figures about sleep can help you understand how sleep works, why it’s important, and the depth of the sleep deprivation problem in the United States.
