Sleep less than eight hours per day makes the body easy victim of the influenza virus. That was the conclusion of researchers at Carnegie Melon University, in work published in the journal "Archives of Internal Medicine" from January 12. The quantity and quality of sleep can affect the functioning of the immune system, lowering the defenses of the body.

A group of 150 healthy volunteers had their quantity and quality of sleep recorded for 14 days. The experts considered the limit of 8 hours of sleep as ideal. The quality of sleep was assessed by the time that the participants really were asleep when they were resting.

After 14 days the volunteers were inoculated with influenza virus by nasal drops containing rhinovirus. The facility was chosen by replicating what happens in the real world. Symptoms of a typical flu appeared in some of the participants, as expected.

The crossing of the data showed a direct relationship between sleep and installation of viral tables. Sleeping seven hours or less per day increased by nearly three times the possibility of influenza occur. Another important finding was that the quality of sleep also affects the defense organ. Losing 10% of the time the quality of sleep can increase by more than 5 times the chance of being infected when flu. According to the researchers, the production of substances that regulate the immune response, called cytokines, is compromised by lack of sleep.
