Document Summary
Biological predispositions work with sleep stressors to drive an insomnia. In jet lag, people circadian rhythms are disturbed and they deal with this by taking otc sleep pills. Unfortunately that sets them up for rebound insomnia when medication is withdrawn, meaning insomnias are worsened. But remember for an issue to be a psychological disorder it has to impair functioning=i. e. impair friendships, driving, schoolwork. Sleep apnea is a difficulty breathing at night. A significant subgroup of people diagnosed with hypersomnolence disorder previously were exposed to a viral infection,such as mononucleosis, hepatitis, and viral pneumonia. In addition to daytime sleepiness, people experience cataplexy: a sudden loss of muscle tone(which is why they fall over) Cataplexy often comes after strong emotions like happiness and sadness. Problems from narcolepsy are first seen in teen years. People whose breathing is interrupted during their sleep often experience numerous brief arousals throughout the night and do not feel rested even after eight or nine hours asleep.
