Have you ever felt far more dehydrated than other times sometimes when you wake up from your sleep? Well, apart from the obvious reason that you might have gone to bed dehydrated in the first place, chances are your sleep or lack of it is more to blame.

Adults who sleep just six hours per night instead of eight may have a higher chance of suffering from dehydration, according to recent a study.

The study highlighted that those who do not feel well after a night of poor sleep are likely to feel dehydrated and may want to consider drinking more water. The findings, published in the journal Sleep, suggest that those who do not feel well after a night of poor sleep may want to consider—not simply poor—as a cause, and drink more water.

Dehydration negatively affects many of the body’s systems and functions, including cognition, mood, physical performance and others. Long-term or chronic dehydration can lead to more serious problems, such as higher risk of urinary tract infections and kidney stones.

The researchers reported that people who slept for six hours had significantly more concentrated urine and 16-59 percent higher odds of being inadequately hydrated compared to adults who slept eight hours on a regular basis at night.

The cause was linked to the way the body’s hormonal system regulates hydration, claim researchers from Pennsylvania State University in the US looked at how sleep affected hydration status.

A hormone called vasopressin is released to help regulate the body’s hydration status. It is released throughout the day, as well as during nighttime sleeping hours, which is what the researchers focused on for this study.

The hormone vasopressin is what gets affected due to a lack of sleep.

“Vasopressin is released both more quickly and later on in the sleep cycle,” said Asher Rosinger, assistant professor at Pennsylvania State University.

“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,” said Rosinger.

“If you are only getting six hours of sleep a night, it can affect your hydration status,” Rosinger said. “This study suggests that if you’re not getting enough sleep, and you feel bad or tired the next day, drink extra water,” he said.
