How much time is the human body spouse to get rest

Infants sleep about 16 hours a day, while teenagers need 9 hours on average.

For most adults, 7 to 8 hours a night appears to be the best amount of sleep, although some people may need as few as 5 hours or as many as 10 hours of sleep each day.

Hope that helped! :)

Behavioral science is the study of human behaviors and how they can be influenced.  by examining patterns in behavior as well as reactions, individuals with behavioral problems can be more adequately treated, resulting in greater mental health of our society/the public.
