duration of sleep with age
School-aged children (6-12 years of age) average approximately 10-11 hours of sleep in a 24-hour period. Research studies suggest that adolescents generally require about 9-9.25 hours of sleep per night ; however, many are getting less than 8 hours of sleep per school night.
Adults average about 7-8 hours of sleep per day. Recent evidence shows an intriguing association between short self-reported sleep duration (6 hours or less) and increased risk for coronary heart disease and diabetes mellitus.
But there was a limit to the benefit; too much sleep was associated with higher rates of diabetes, obesity and mental health issues. Hereâs how much sleep they recommend for children at different ages: Babies, 4 to 12 months: 12 to 16 hours. Children, 1 to 2 years: 11 to 14 hours.
