Those who do not drink enough sleep less, while proper hydration improves sleep quality and therefore life
According to the study “Short sleep duration is associated with insufficient hydration”, published in the journal Sleep, there is a link between dehydration and low sleep.
The study involved 20,000 healthy young people. Those who slept only six hours a day during the test had significantly higher levels of dehydration than those who slept eight. According to the results of the analysis, high values of urine density (over 1020 g / ml) and salt content (over 831 mOsm / kg) showed poor hydration and led to a further reduction in sleep duration by approximately two hours.
Scientists explain this by the fact that with insufficient hydration the body protects itself and to prevent fluid loss produces vasopressin, an antidiuretic hormone that affects sleep patterns.
– During sleep, the body goes through numerous and complex processes to restore the overall health of the body. And the circadian rhythm controls the amount of fluid in the body, – explains the president of FEMTEC, director of the Reference Center for Integrated Medicine of the World Health Organization at the University of Milan Umberto Solimene, reports ANSA.
In addition, dehydration can also cause fatigue, headaches and muscle cramps, which complicate falling asleep and negatively affect sleep quality. Therefore, the expert advises, to maintain proper hydration during the day to drink mineral water with a high content of trace elements. They help to avoid night dehydration.
