A remarkable study on sleep was conducted with the participation of approximately 500 thousand people. This research revealed that the optimal sleep duration for adult humans is 7 hours. People who sleep 7 hours a day are healthier both in terms of mental health and in terms of brain functions.
A group of scientists working at Fudan University and Cambridge University, serving in China, conducted a comprehensive research on sleep, one of the most important elements of life. Within the scope of the research carried out with the participation of 498,277 people aged 38-73 in the United Kingdom , it was concluded that the optimal sleep duration of a person is around 7 hours . Sleeping less than 7 hours or sleeping too much affects human health negatively.
Within the scope of the research, a mental health questionnaire was applied to 157,000 people. In addition, 48,500 participants were monitored during sleep. Combining all the data they obtained, the scientists identified a “U”-shaped link between sleep duration and health. 7 hours of sleep had always coincided with the optimal spot in this letter U. However, experts state that this research is observational and it is not correct to use a clear statement that sleeping less or more than 7 hours will definitely cause health problems .
Brain structure and genetic structure are also effective in ideal sleep time.

According to scientists, sleep duration is very important for a person to be healthy both physically and mentally. However, individuals ‘ brain and genetic structures are also important. Scientists state that the optimal sleep duration may vary for each person, and this research represents a general average . So, what kind of problems are experienced in the body as the sleep time falls below 7 hours and goes above it?

In the table above, we see the relationship between sleep duration and mental health . Anxiety symptoms are minimal after 7 hours of sleep. The sleep time when you are at the highest level of calmness is also 7 hours. As you see; 7 hours of sleep always coincides with the most productive point of the U relationship.
