PRINCETON, NJ -- Fifty-nine percent of Americans get seven or more hours of sleep at night, while 40% get less than seven hours. Those figures are largely unchanged from Gallup polls in the 1990s and 2000s, but Americans, on average, slept much more in the 1940s.mplications. U.S. adults likely get less sleep than would be ideal, with the average reported 6.8 hours below the minimum recommendation of seven hours per night.
REM sleep occurs at intervals of one to two hours, and is variable in length. REM sleep is characterized by irregular breathing and heart rate, and involuntary muscle jerks. Most adults need around eight hours of sleep on a regular schedule to function well, although some require less, and others more. (It has been said that men need an hour less sleep than women.) Children, particularly teenagers, often need nine or ten hours for optimal functioning.
