Premature sleep can lead to dehydration

It is almost normal for me to feel embarrassed after a night of throwing and turning or staying too late. But new research suggests that it may be more than just a lack of sleep: you can be dehydrated, researchers say, and drinking more water can help you feel better.

Study released this week in the journal Sleep, found that people who regularly reported sleeping only six o'clock in the night 16 to 59% more likely to be "inadequately hydrated" (based on urine sample analysis) than those who said they normally slept eight. In the United States and Chinese adults, a total of 25,000 people participated in the study – and the results were consistent in both populations.

This does not mean that people who sleep less and drink less; in fact, the authors of the study actually controlled the total fluid consumption of some participants. They found that even when people said they were drinking the same amount, those who slept were less likely to have a more concentrated urine and other signs of dehydration.

So what's going on? The authors of the study say it is probably associated with a hormone called vasopressin, which helps regulate the state of hydration of the body.

Vasopresin is released day and night, but production actually rises later in the sleep cycle, said lead author Asher Rosinger, assistant professor of behavioral health and anthropology at Penn State University in a press release. "So, if you wake up earlier, you may miss a window that releases more hormones, causing a body hydration disorder," he added.

The authors point out that a worse sleep is associated with earlier studies with chronic kidney disease and say that dehydration can be a significant trigger of this relationship. Long-term dehydration can also increase the risk of kidney stones and urinary tract infections.

Since the research relied on sleep data and only looked at the urine results at one point, it only found the connection between two causes and consequences. Future studies should consider this relationship for a week, the authors wrote in their work to understand how the moisture and sleep conditions of people change on a daily basis.

The National Sleep Foundation suggests that adults need between seven to nine hours of sleep and that it is best to maintain a consistent sleep time and waking time. (In this study, sleeping more than nine hours a night did not have any effect, in both directions, on the status of hydration.)

Of course, you do not really need it more The reason why sleeping is bad for you is also associated with a greater risk of cardiovascular disease, dizziness, weight gain (even when it is not related to diarrhea) and diabetes, to name but a few. This can also cause short-term problems, such as irritability, concentration problems, memory problems, and sleepiness.

However, dehydration itself has also shown to cause headaches and fatigue and affect mood, aesthetics and physical performance – which may be adding to the already negative effects of a nightmare, the authors say. "This study suggests that if you do not get enough sleep, and the next day you feel bad or tired, drink extra water," said Rosinger.
