Sleeping less than seven hours per night increases three times the chances of catching a cold, while even less time resting, the chances grow five times. This is the main conclusion of a study conducted in Pittsburgh, USA, by professionals at Carnegie Mellon.
"Our study is the first to mention that sleeping less than the recommended eight hours, decreases the body's resistance against certain viruses. This means that developing regular sleep habits and routine contributes to the functioning of the immune system's ability to defend it, "says lead study author, Sheldon Cohen.
addition, the conclusions from the experience as part of the January issue of the journal Archives of Internal Medicine, Sheldon argues that previous tests had shown that sleep eight hours a day usually recommended by the specialists also contributes to lower rates of heart disease and death.

Moreover, beyond the questionnaire, participants were given nose drops to be placed in addition to reporting any symptoms related to colds, nasal discomfort or flu. As for the tests more "strict" or conclusive, the 153 people mucus samples were taken and blood tests to test the virus and answers the organism to these agents.
"We found that those who had been sleeping less than seven hours were three times more likely to get sick of catching a cold. On the other hand, those who lose more than 8% of their time off every night, because it slow to wake up or fall asleep, "have their chances of getting sick when exposed to a virus increased five times," noted Dr. Cohen who also added that "beyond the numbers and others, the research aims to highlight the importance of protecting body not only eating well and being active but also relaxing the amount of time required by activities that everyone does. "
