insufficient sleep syndrome
Insufficient sleep syndrome happens when you regularly don’t have enough time to get as much sleep as you need. This can happen because of your habits or responsibilities. A doctor can test how much sleep you get and the timing of your sleep by having you keep a sleep diary. They may also ask you to wear a special sensor called an actigraph, which measures your physical activity levels. Insufficient sleep syndrome goes away if you start getting as much sleep as you need.
