Too much sleep can lead to dehydration

It's perfectly normal for you to feel awkward after the night of throwing and turning or stopping. But new research suggests that more can occur than deprivation of freedom of sleep: you can also be dehydrated, researchers say, and drinking more water can help you feel better.

A study published this week in the journal Sleep, found that people who reported sleeping for only six hours at night were 16 to 59% more likely to be "inadequately hydrated" (based on analyzes of their urine samples) than those who said they normally sleep eight. Both adults in the United States and the Chinese participated in the research – about 25,000 people in general – and the results were consistent in both populations.

This does not mean that people who sleep less drink less; In fact, the authors of the study really controlled the total consumption of fluids among some participants. They found that even when people reported the same amount, those who slept less likely had more concentrated urine and other signs of dehydration.

So what's going on? Study authors say this probably has to do with a hormone called vasopressin, which helps regulate the hydration status of the body.

Vasopressin occurs every day and night, but production is really a ramp later in the sleep cycle, chief author Asher Rosinger, assistant professor of biophysical health and anthropology at Penn State University said in a press release. "So, if you are waking up earlier, you may miss that window where more hormones are released, which causes a disorder in body hydration," he added.

The authors point out that it is bad early associated with previous studies with chronic kidney disease and they say that dehydration can be a significant driver of this relationship. Long-term dehydration can also increase the risk of kidney and urinary tract infections.

Because the study relied on sleep condition data that only logged in and only looked at the results of urine at just a moment, they could only find a link between the two, not the cause-and-effect relationship. Future studies should look at this relationship over the week, the authors wrote in their work, to understand how human hydration and sleeping conditions are changing every day.

The National Sleep Foundation suggests that adults need seven to nine hours sleeping night-time, and that it is best to keep their time for sleep and waking as much as possible. (In this study, sleeping for more than nine hours at night did not have any effect, in any direction, on the status of hydration.)

Of course, you really do not need it the second The reason why hiding is bad for you: it is also associated with a higher risk of cardiovascular disease, overeating, weight gain (even when not related to overeating) and diabetes, to name a few. It can also cause short-term problems, such as irritability, concentration difficulties, memory problems, and sleepiness.

However, it has been shown that dehydration causes headache and fatigue and affects mood, cognition and physical performance – which can lead to greater negative effects of the accident, authors say. "This study shows that if you do not get enough sleep and you feel bad or tired the next day, drink more water," Rosinger said.
