Sleeping six hours a night instead of eight can give you a greater chance of waking up, according to a study by Penn State.
WASHINGTON – Sleeping six hours a night instead of eight can give you a better chance of waking up, according to a study by Penn State.
"This study suggests that if you do not get enough sleep and you feel bad or tired the next day, you can drink extra water," said lead author Asher Rosinger, assistant biobehavioral health assistant at Penn State in a press release.
The researchers said a hormone that regulates hydration could be interrupted in short sleepers. The hormone called vasopressin is released all day and night during sleep, but sooner and later in the sleep cycle.
So if you wake up earlier, you might lose the window where more hormone is released, causing an interruption in body hydration, "Rosinger said.
The study, published in the Sleep Journal, involved more than 20,000 adults who were questioned about sleeping habits. Participants also provided urine samples that were analyzed for biomarkers of hydration.
Adults who had only six hours of sleep each evening had a significantly higher concentration of urine and were 16 to 59% more likely to be dehydrated than those who slept for eight hours.
Dehydration can negatively affect your mood, physical performance and mental processes.
