Approximately 70 million people in the United States suffer from sleep problems and more than half have a chronic sleep disorder. There are more than 100 varieties of sleep disorders, which means it’s important to get a proper diagnosis with individualized care. Most adults need seven to eight hours of sleep each day. You know you’re getting enough sleep if you feel refreshed when you awaken and remain alert throughout the day. If you consistently have trouble sleeping or are very sleepy while you are awake, you may need a professional evaluation to determine if you have a sleep disorder.
