How much sleep do you need?

While some people experience acute effects of sleepless nights, others would cope successfully after several sleepless nights.

In the United States sleep average is about 6.9 hours per night. For most people, sleep should last between 6 and 9 hours a night and not less, as this could lead to some serious consequences to the body. Lack of sleep directly affects the quality of life, cognitive functions, attention and vigilance.

Lack of sleep can affect your memory

Following a study of 2 weeks conducted in 2003, a group of subjects was put to sleep each 4, 6 and 8 hours of sleep per night. During the day, each group was subjected to a memory test. Not surprising was that people in the group who slept 8 hours per night didn’t show any cognitive decline.

Lack of sleep and exhaustion harm our daily performances and general health. People with sleep deficits are less alert during the day. They are inattentive and can’t concentrate on the tasks they have to accomplish; memory is affected. Also, sleep deprivation increases the risk of heart disease, stroke, dementia; these are just some of the long-term effects. The consequences arising immediately from sleep deprivation could also be harmful.


Neither too little nor too much sleep

Each of us should establish a rigorous program of sleep that we are willing to follow. In this case, the routine is more than indicated. Few hours of sleep or too many hours will not help you to reach your full energy potential. According to experts, less than 6 hours of sleep per night are too few. More than 9 hours of sleep a night are too much. Although statistics show that the hours needed for sleep vary from person to person, though we generally need to sleep 7-8 hours. In the case of adults, less than 6 hours or more than 9 hours are associated with metabolism disorder and heart problems.
