Lack of proper sleep associated with dehydration

Adults who sleep only six hours a day instead of eight have a greater chance of dehydration.

The study emphasized that those who do not feel well after a night of bad sleep may feel dehydrated and may want to consider drinking more water.

Dehydration negatively affects many of the body's systems and functions, including cognitive functions, mood, physical fitness, and more. Prolonged or chronic dehydration can lead to more serious problems, such as increased risk of urinary tract infections and kidney stones.

"If you have only six hours of sleep overnight, it can affect your hydration status. This study suggests that if you do not sleep well enough and feel bad or tired the next day, drink extra water," said Asher Rosinger, Assistant Professor at University of Pennsylvania in the USA.

For the study, published in the SLEEP journal, the team included more than 20,000 adults and examined how sleep affects their hydration status and the risk of dehydration.

Participants were examined about their sleeping habits and their urine samples were collected.

The results showed that adults who reported having slept six hours had significantly more concentrated urine and 16 to 59 percent higher chances of inadequate hydration compared to adults who slept eight hours regularly at night.

The cause was related to the release of vasopressin – a hormone – to regulate the hydration status of the body during the day, as well as during the night hours of sleep.

All data are observational, therefore the results of the association should not be perceived as causative, say the researchers.
