What is the proper length of sleep? Most people state that they need seven-none hours a day to feel good. The majority sleeps eight-seven hours and complains on exhaustion, weakness and bad mood. On the contrary, there are people that feel great and are extremely active after a three hour sleep. Statistics shows that these differences between people are modified on the genetic level. In order to track the situation, scientists compared the average length of sleep in the nineteenth and twentieth century and the result was 20% less than in the nineteenth century. That means that we sleep half an hour less that people did two centuries ago. These changes break biorhythm and as a result we have problems with health, immune system and psychics. But can you blame people for spending time on good rest? I know nobody that does not like sleeping. This stage of your body helps to recover from exhaustion and weakness; it is good for the immune system and as important as food and sex. There was an unspoken rule in our family, once we see someone sound asleep; there is no existing fair reason to wake up a person.

Everything may only look fine, but everyday problems keep people busy and stressed. Children and parents stand up at the break of dawn to get prepared for work and studies. There are some of the professions that require their representatives to be present in the middle of the night. Students sit up late and study for their tests, exams, doing assignments. Some people start to be really active after dark. Night clubs, pubs, casinos and other similar establishments are extremely popular among city-dwellers, especially young and rich people. And then when the dawn breaks, they stand up after two-hour sleep and start all over again. Sometimes people do not even have a sleep; just continuously keep being involved in things over 48 hours in the row. Certainly these people feel stressed, exhausted and are extremely aggressive. This rhythm reflects on the health of these people.

Gaining weight may also be a result of sleepless nights, as professor from Canada says. Sleep is a gift that is meant for us to use to live longer and happier. When the body asks for rest and relaxation, it is high time to allow it. To sleep well you have to be active during the day and keep to the daily plan. Sleep is what brings both pleasure and profit.
