If a long sleep does not give a person a sense of rest, then this may signal health problems.
The body's need for sleep can be determined by individual characteristics and vary depending on age, the presence of diseases and stress, and the level of physical activity. Experts usually recommend that students sleep about 9 hours a day, teenagers - from 8 to 10 hours. Adults need 7-8 hours of sleep.
"If you're sleeping more than nine hours a night and you don't feel rested, it could be a sign of a serious health problem," said somnologist Michelle Drerup of the Cleveland Clinic's Sleep Disorders Center.
The specialist said that increased drowsiness can indicate such disorders.
Mental disorders. Sleeplessness is one of the characteristic symptoms of depression, it is observed in 15 percent of people with this disease.
Sleep disturbance. Sleep apnea, in which repeated pauses in breathing occur, is a common cause of oversleeping. People with narcolepsy, who tend to fall asleep suddenly, may also experience excessive daytime sleepiness and fragmented nighttime sleep.
Unbalanced diet. If the diet does not provide the body with the necessary amount of B vitamins, it also contributes to increased sleepiness.
Other. The reason for a person's need for more sleep can be medication, as well as abuse of psychoactive substances, in particular alcohol.
