Insufficient sleep can cause high blood pressure, heart disease, bone loss and have negative impact on your health.
According to national sleep foundation, the appropriate sleep duration for newborns is between 14 and 17 hours, between 12 and15 hours for infants, 11 and 14 hours for toddlers, 10 and 13 hours for preschoolers, 9 and 11 hours for school-aged, 8 and 10 hours for teenagers, 7 and 9 hours for young adults and 7 and 8 hours for older adults.
