Teenagers (14 to 17 years): 8 to 10 hours of sleep. Young adults (18 to 25 years): 7 to 9 hours of sleep. Adults (26 to 64 years): 7 to 9 hours of sleep. Older adults (65 years or older): 7 to 8 hours of sleep. Although most men and women need about seven to eight hours of sleep per night, their sleep patterns are generally different.

For most adults, 7 to 8 hours a night appears to be the best amount of sleep.EM sleep stimulates the brain regions used in learning. This may be important for normal brain development during infancy, which would explain why infants spend much more time in REM sleep than adults (see Sleep: A Dynamic Activity). Like deep sleep, REM sleep is associated with increased production of proteins.
