It's perfectly normal if you stay and turn around or remain late at night. But new research suggests that guilty can be more than just a lack of sleep: you can also be dehydrated, researchers say, and drinking more water, it can help you feel better.
The study, which was published this week in the journal To sleep, found that people who usually slept regularly for only six hours at night were 16 to 59% more often "inadequately hydrated" (based on urine sample analysis) than those who said that there were usually eight beds. The study was attended by both adults in the United States and China – some 25,000 people – and the results were the same in both populations.
This does not mean that people who sleep less drink less; In fact, the authors of the study actually controlled total fluid intake among some of the participants. They discovered that even if people reported alcohol consumption in the same amount, less likely to have washed, most likely urine and other dehydration were more concentrated.

So what's going on? The authors of the study indicate that it is most likely associated with a hormone called vasopressin, which helps regulate the body's hydration status.
Vasopressin is released both day and night, but the output actually ramps later in a sleep cycle, said lead author Asher Rosinger, Associate Professor of Biochemical Behavioral Health and Anthropology at Penn State University. "So, if you dream early, you can miss a window that releases more hormone, causing a disorder of hydration of the body," he added.
The authors point out that previous studies of chronic kidney disease are associated with poor sleep, and they say that dehydration can be an important driver of this link. Prolonged dehydration may also increase the risk of human kidney stones and urinary tract infections.

Since the study was based on self-contained sleep data and looked at the results of urine only at a glance, it could only find the link between the two rather than causal relationships. Future studies should look at this relationship during the week, the authors wrote in their article to understand how people change day by day, moisturizing and sleeping.
The National Sleep Foundation suggests that adults should have seven to nine hours of sleep at night, and it is best to keep your bedtime and waking as much as possible. (In this study, when sleeping more than nine hours at night, there was no effect on the hydration status in both directions).
Of course, you really do not need it other The reason why you sleep is bad for you: it is also associated with increased risk of cardiovascular disease, overeating, weight gain (even if it is not overeating) and diabetes, naming some. This can cause temporary problems, such as irritability, difficulty concentrating, memory problems, and sleeping.
Authors have also shown that dehydration causes headaches and fatigue and affects mood, cognition and physical activity, which may be due to the already negative effects of insomnia at night. "This study suggests that if you do not get enough sleep the next day and feel bad or tired the next day, drink extra water," Rosinger said.
