The Value of Getting Enough Sleep

Sleep stimulates the growth hormone, especially in children. For others, sleep provides a multitude of benefits. Sleep helps repair body tissues, keep heart and blood vessels healthy, strengthen the immune system, and regulate appetite and weight. If you miss out on a few nights’ sleep, you will feel below par and your attention, learning, and physical levels will suffer. People’s sleep requirements change through life. Newborns need 16 to 18 hours of sleep a day, preschool children, 10 to 12 hours, and older children and adolescents, at least nine hours. Adults sleep needs also vary. Some adults need at least nine hours of sleep. Others feel fine on less than seven hours. Generally, the younger you are, the more sleep you need.
