What is insomnia?
Insomnia is a sleep disorder that can make it hard to fall or stay asleep, or may cause you to wake up too early and not be able to get back to sleep.
Insomnia is the most common sleep disorder in the United States. Roughly half of all people experience acute bouts of insomnia, and approximately 10% of Americans chronically suffer from the condition.
Most cases of insomnia are the result of poor sleep habits, depression, anxiety, lack of exercise, chronic illness, or certain medications.
