  • Lifespan changes in sleep
    • Infancy - Babies tend to sleep about 16 hourse a day, waking up everyhours or so. Infants sleep stages similar to adults called quiet and active sleep. By the age of 6 months a circadian rhythm has become established and by the age of one infants usually sleep mainly at night with 1/2 naps during the day.
    • Adulthood & old age - 'Normal' adult sleep is typically about 8 hours per night (25% REM sleep) Childhood parasomnias are more rare in adulthood but things such as insomnia are increasing. With increasing age, total sleep time remains the same, although older people have more difficulty going to sleep and wake up more frequently. Sleep patterns do change; REM sleep decreases to about 20%
    • Childhood -  byt the age of 5 children have EEG patterns that look like that of an adult but they sleep more (about 12 hours a dya) and having more REM activity. During childhood it is not uncommon for children to experience parasomnias.
    • Adolescence - In adolescence the need for sleep increases slightly, to about 9-10 hours a night. Circadian rhythms also change so that teenagers feel naturally more awake later at night and have more trouble getting up early.
