Sleep is ‘individualized’ and the sleep time required varies from person to person. There are two factors that influence the amount of sleep an individual needs. According to the Harvard School Division of Sleep Medicine, those factors are age and genetics.

Genetics do not only influence how much sleep you need, but also your sleeping pattern and waking time, or your preference to perform certain tasks at different times of the day. The majority of adults require 7.5 to 8 hours sleep within a time period of 24 hours. A very small percentage of the population (3%) can function satisfactorily with only 6 hours of sleep per day thanks to their genetics.

Customarily, the older you get the less sleep you need to function as shown by this list of recommended sleeping times. •Newborns (1 to 2 months) – 10.5 to 18 hours •Infants (3 to 11 months) – 10 to 14 hours •Toddlers (1 to 3 years) – 12 to 14 hours •Preschoolers (3 to 5 years) – 11 to 13 hours •School-aged children (5 to 12 years) – 10 to 11 hours •Adolescents (12 to 18 years) – 8.5 to 9.5 hours •Adults (18 years to the end of life) – 7.5 to 8.5 hours

Studies have shown that those who sleep too much or too little suffer from a higher mortality rate than those who sleep just long enough.
