"If you are only getting six hours of sleep a night, it can affect your hydration status," coauthor Asher Rosinger said in a statement. "This study suggests that if you're not getting enough sleep, and you feel bad or tired the next day, drink extra water."
The scientists believe vasopressin, a hormone that helps regulate hydration in the body, is responsible for the link between hydration and sleep.
“Vasopressin is released both more quickly and later on in the sleep cycle,” Rosinger explained. “So, if you’re waking up earlier, you might miss that window in which more of the hormone is released, causing a disruption in the body’s hydration.”
Dehydration can negatively affect many of the body’s systems and functions. It can alter your cognition, mood and physical performance and can lead to more serious issues like urinary tract infections and kidney stones.
