Teenagers respond and do better in school when learning during biologically optimal times. A current line of research suggests there shouldīe later school start times for teenagers, with earlier school times reserved for younger children. As a result, they are often sleep-deprived and tired during the day. Much as 9 or 10 hours of sleep a night but often need to awaken early in the morning for school. We commonly see delayed sleep phase disorder in young teenagers, whose circadian rhythm naturally shifts from a bedtime of 8 p.m. The patient, in this case, has great difficulty staying awake later into the night. This disorder occurs when a patient falls asleep earlier than desired but awakens very early in the morningĪfter getting a full night’s sleep. If you are able to fall asleep easily on resuming a normal bedtime after a few late nights, then you do not have delayed sleep phase disorder.Īn opposite but similar condition, called advanced sleep phase disorder, is commonly seen in older adults. People with delayed sleep phase disorder are unable to return to a normal schedule, despite trying, and end up spending a prolonged time in bed awake before falling asleep. Many patients with delayed sleep phase disorder consider themselves “night owls.” It’s common for us to delay our sleep and wake times because of late-night parties and other social activities,īut this does not mean we have the disorder. In delayed sleep phase disorder, the sleep cycle is pushed later into the night, with a delayed natural morning wake time. In some people, these rhythms can shift, causing sleep and wake times to fall outside a desired schedule. Our bodies are biologically programmed, through circadian rhythms, to sleep at night and be alert during the day. Insomnia is also usually due to some specific cause, suchĪs a medical or psychiatric disorder like depression. Most insomnia patients have a combination of these symptoms, such as difficulty falling asleep as well as staying asleep. Those with insomnia, on the other hand, may have difficulty falling asleep or staying asleep, wake too early or feel Obtaining a full night’s sleep and typically sleep until late morning or early afternoon. Patients with delayed sleep phase disorder, or D.S.P.D., usually have difficulty falling asleep, but once they fall asleep they have no difficulty Delayed sleep phase disorder and insomnia are two different disorders.
