Better Sleep Month
Sleep is a natural body function during which we are relatively unconscious and the muscles that we normally control are relaxed. The result of sleep is a refreshment of the nervous system (including the brain) and of the muscles.
Sleep plays a central role in everyone's life.
Statistics say that 95 percent of Americans have difficulty sleeping at some time in their lives.
As we age, our bodies normally require less sleep. Infants require from 12 to 14 hours while seniors may require from 6 to 8 hours. There is an interesting sex difference in duration of sleep. The average male adult sleeps 8 hours while the average female sleeps 9 hours.
