AP PSYCHOLOGY

Detailed explanation-1: -Circadian rhythm sleep disorders involve one of these problems: You have a difficult time falling asleep. You struggle to stay asleep and often wake up several times during the sleep cycle. You wake up too early and can’t go back to sleep.

Detailed explanation-2: -Recurrent hypersomnia (also known as Kleine-Levin syndrome) is characterized by periods of excessive sleeping up to 20 hours a day, which lasts from 2–35 days. Between hypersomnia episodes, the patient is cognitively normal and not sleepy.

Detailed explanation-3: -Bright light in the evening, 2 hours before bedtime, will make you feel sleepy and fall asleep later. If you have trouble falling asleep, dim the lights 2 hours before you want to go to sleep. If you get sleepy too early in the evening, go into a well-lit area to feel more awake.

Detailed explanation-4: -Disruptions in your sleep patterns can be temporary and caused by your sleep habits, job, or travel. Or a circadian rhythm disorder can be long-term and caused by aging, your genes, or a medical condition.
