It is perfectly normal to feel confused over the overnight throwing and turning or staying too late. But new studies suggest that the cause may be more than just a sleep disorder: You can also dry up, researchers say and drinking more water can help you better.
The study was released this week in the journal To sleep, it was found that people who reported regularly sleeping only six hours at night were 16-59% more likely to be "poorly hydrated" (based on urinary analysis) than those who said they normally slept eight. Both the United States and Chinese adults participated in the study – approximately 25,000 people – and the results were consistent between both populations.
This does not mean that people who sleep less, also drink less; In fact, the researchers actually controlled the total consumption of liquid by some participants. They found that although people told the line the same amount, those who slept less were probably more concentrated urine and other signs of dryness.

So what's happening? Researchers say it is probably associated with vasopressin hormone that helps regulate body fluidization.
Vasopressin releases both day and night, but the output really rises later in the sleeping cycle, said Associate Professor Asher Rosinger of Assistant Professor of Penn State University, associate professor of biological behavior and anthropology at Penn State University. "So, if you wake up earlier, you may ignore a window where more hormone releases, causing interference with body hydration," he added.
The authors point out that poor sleep has been associated with previous chronic kidney disease studies, and they say that dehydration can be a significant link to a test. Long-term dehydration can also increase the risk of kidney stones and urinary tract infections.

Since the study was based on independently reported sleeping data and looked at urine results at just one moment, it was only able to find the combination between the two-and-cause-to-relationship ratio. Upcoming studies should look at this relationship over the course of a week, writers write in their paper to understand how people's fluidization and sleep status change every day.
The National Sleep Foundation suggests that adults should get seven to nine hours of sleep per night, and it is best to keep the sleep and wake-up time as consistent as possible. (In this study, sleeping more than nine hours at night did not seem to affect either direction in a hydration situation.)
Of course you do not really have to second The reason why sleeping is bad for you is also related to higher risk of cardiovascular disease, overeating, weight gain (although not related to overweight) and some diabetes. It can also cause short-term problems such as irritability, difficulty concentrating, memory problems and sleepiness.
But dehydration itself has also been shown to cause headaches and fatigue and affect mood, cognition, and physical performance – which can increase the already negative effects of sleepless night. "This research suggests that if you do not get enough sleep, and you feel bad or tired the next day, drink more water," Rosinger said.
