How many hours does a human being sleep in his life?

The amount of hours of sleep necessary are still the subject of debate despite the well-known recommendations that guarantee this you need to sleep between seven and eight hours a dayin the case of adults.

Although some experts question this figure, doctors agree that this is the case time is enough so that the body recovers energy and the brain can process memories, among other functions.

Regardless of the controversy, the truth is that the majority of people spend a third of the day sleeping and that, according to logic, another eight hours should be dedicated to work and eight to free time. This proportion is maintained throughout life and, therefore, translates into a rather surprising number of years spent sleeping.

How many hours does a human being sleep in his life?

The Mayo Clinic in the US states that “the recommended amount of sleep for a healthy adult is at least seven hours”. And he adds that you don’t need to sleep more than eight hours to feel good.

The amount of hours decrease with age as the National Sleep Foundation, also American, explains. Newborns need to sleep between 14 and 17 hours a day; newborns, between 12 and 13 hours; small children (1 to 2 years old), between 11 and 14 years old; preschool children (3 to 5 years old), 7 to 12 years old; and school-age children (6 to 13 years old), from 9:00 to 11:00.

Adolescents (ages 14 to 17) should sleep 8.5 to 10 hours a day; young adults (18 to 25 years) and adults (26 to 64 years) from 7 to 9 hours; and the older adults (over 65 years), between 7 and 8 hours.

According to the Mayo Clinic, several factors influence the quality of sleep. For example, its frequent interruption; previous sleep deprivation, which leads to having to spend more hours to recover it; pregnancy and aging.

In this sense, he states that “older adults need approximately the same amount of sleep as young adultsbut as they age, their sleep patterns may change.”

Those over 65” tend to sleep lighter, take longer to fall asleep and sleep for shorter periods of time compared to younger adults and tend to wake up more times during the night,” reports the Mayo Clinic.

As for the number of years people sleep, an estimate of Freedom of thought, which took into account life expectation of 78.6 years, established as 25 years.
