Adults who last only six hours per night instead of eight may be more likely to suffer from dehydration, according to a study.
The study indicated that those who do not feel well after a poor night of sleep may feel dehydrated and may want to consider drinking more water.
Dehydration adversely affects many of the systems and functions of the body, including cognition, mood, physical performance and others. Prolonged or chronic dehydration can lead to more serious problems, such as a greater risk of urinary tract infections and kidney stones.
"If you are only getting six hours of sleep at night, it can affect your hydration state. This study suggests that if you are not asleep long enough, and you feel ill or tired the next day, drink extra water," said Asher Rosinger . , Assistant Professor at the University of Pennsylvania in the United States.
For the study, published in SLEEP magazine, the team included more than 20,000 adults and studied how sleep affected its hydration state and the risk of dehydration.
The participants were investigated about their sleeping habits and the urine samples were collected.
The results showed that adults who reported that they slept six hours had significantly more concentrated urine and 16 to 59 percent the highest probabilities of being inadequately hydrated compared to adults who slept eight hours regularly at night.
The cause was related to how vasopressin (a hormone) body is released to help regulate the body's hydration throughout the day, as well as during nighttime sleeping hours.
All the data are observational, therefore, the results of the association should not be considered as causatives, according to the researchers.
