Shorter Sleep Can Lead to Dehydration

A study suggests that those who don't feel well after a night of poor sleep may want to consider dehydration—not simply poor sleep—as a cause, and drink more water.

Researchers looked at how sleep affected hydration status and risk of dehydration in U.S. and Chinese adults.

A hormone called vasopressin is released to help regulate the body's hydration status.

"If you are only getting six hours of sleep a night, it can affect your hydration status," Rosinger said.

Future studies should use the same methodology across sites and examine this relationship longitudinally over the course of a week to understand baseline sleep and hydration status, Rosinger said.
