Sleep, the duration of which is less than six hours per day leads to dehydration. This was the conclusion reached researchers at the University of Pennsylvania. About this on their pages reported in the journal Oxford Academic, reports Newsmir.info.
To obtain these results a survey was conducted more than 25 thousand residents of the United States of America and China on the number of hours of sleep. Also they were selected urine samples. As it turned out, people who slept less than six hours a day, the urine was more concentrated, and 16-59%. This figure indicates an insufficient amount of fluid in the body.
Scientists believe that reduced water content in the urine may indicate the violation of production of vasopressin, an antidiuretic hormone. This substance is responsible for retaining fluid in the body and is directly involved in the work of the cardiovascular system of the body. Thus, the researchers came to the conclusion that this factor causes poor health, with significant lack of sleep. In order to alleviate this condition they are advised to immediately after waking drink a glass of water.
