When you ask someone how much sleep is needed, the common answer and belief is 7 to 8 hours each night to feel at your best the following day. While that does hold true for the most part, it is not a number that is set in stone. There are going to be different factors between each person that can make the magical number higher, or lower depending on your age, body, sleep quality, etc.
The fact is, infants, kids, teens, adults, and seniors all have a different requirement for sleep. While sleep is important when young, as a person ages sleep becomes less needed in many. Everybody is different, so sleep requirements are too, naturally.
Newborns – At this stage in life, the body is just starting the growing process, both inside and out. Sleep is an important factor in the body healing, repairing and growing. 14 to 17 hours daily is a good range at this age.
Infants – Being a little older than a newborn, the body it still growing and needs it’s ‘beauty sleep’ as they say. Although, not as much sleep will be needed at this stage, with 12 to 15 hours daily being a sufficient amount for the body to do it’s thing.
Child and Teens – At this stage in life, the average sleep requirements fall into the ‘normal range’ that people are more common with. The body continues to grow, but at a reduced rate and this leads to less sleep requirements, with 8 to 10 hours being sufficient.
Adults – At this stage, the body mostly repairs itself and growth has probably stopped. 7 to 8 hours is common, but the needs can vary.
Seniors – After age 65, it is common for people to sleep less than 7 hours and feel more alert.
