New research suggests that insufficient sleep can cause dehydration by interfering with the release of a hormone that is crucial for controlling hydration.
Sleep dependence has a wide range of negative effects on human health.
Not only is insufficient sleep deprivation and attention, but prolonged sleep deprivation increases the risk of type 2 diabetes, hypertension, obesity and respiratory disease.
Some studies have recently shown that insomnia increases the risk of kidney disease and premature death. The kidneys play an important role in hydration and drink more water improves kidney health.
However, few studies have investigated the effects of sleep deprivation on the body’s hydration levels. New research aims to fill this gap. The study’s leader was Asher Rosinger, Ph.D., a deputy professor of biohygiene care at Pennsylvania State University at State College.
The recent study, which explores the effect of insufficient sleep at the level of hydration among adults from the United Kingdom States and China, was recently published in the magazine Sleep.
Rosinger and colleagues analyzed data available from two major studies: National Health and Nutrition Examination Survey and Kailuan Kailuan Study.
In summary, researchers surveyed the record of over 20,000 healthy young adults who had left urine samples and completed questionnaires regarding their sleepy habits.
The researchers examined the urine for two markers of dehydration: gravity and osmolality. Rosinger and the team also applied logistic regression models to evaluate the link between hydration and sleep time.
They found that people who regularly had 6 or less sleep of sleep each night had more concentrated urine than those who received about 8 hours a night. “Short sleep was associated with higher odds of inadequate hydration in [American] and Chinese adults compared to sleeping 8 hours,” explains the authors.
More specifically, people who reported that they regularly slept for 6 hours or less each night were 1
6-59 percent more likely to dehydrate than those who slept for 8 hours a night.
Finally, the study found no association with getting 9 or more hours of sleep per night.
In the comments to the results, the main author noted: “If you only get 6 hours of sleeping one night it may affect your hydration status.” He added:
“This study suggests that if you do not get enough sleep and you feel you bad or tired the next day, drink extra water, “Asher Rosinger.
Although the new study is pure observational and does not show causal link, scientists believe that hormone vasopressin may be responsible for the connection between too little sleep and lack of hydration.
Vasopressin is an antidiuretic hormone that controls body water balance during day and night.
“Vasopressin is released sooner and later in the sleep cycle,” explained Rosinger, adding: “If you wake up earlier, you can miss the window where more of Hor Mone is released, causing a disruption to the body’s hydration.”
Researchers should further assess the relationship between dehydration and sleep disturbance, the author’s note. For example, longevity studies can determine the baseline hydration levels and retest them after a week of insufficient sleep.
Dehydration has different adverse health effects. It can cause muscle weakness, headache and fatigue. Dehydrated can also affect mood and impair cognition.
