According to medicalnewstoday.com, the new study led by Dr Asher Rosinger, an assistant professor of Bio-behavioral Health at the Pennsylvania State University, USA, showed the effect of insufficient sleep on hydration levels among adults.
The study published in the journal Sleep, stresses that insufficient sleep does not only impair attention and judgment, but prolonged sleep deprivation also raises the risk of type 2 diabetes, high blood pressure, obesity, and respiratory disease.
Rosinger and colleagues analysed the data available from two large studies: the National Health and Nutrition Examination Survey and the Chinese Kailuan Study.
The researchers examined the records of over 20,000 healthy young adults in the US and China, who had provided urine samples and completed questionnaires concerning their sleeping habits.
They found that people who regularly got six or fewer hours of sleep each night had more concentrated urine than those who got about 8 hours per night.
The authors explained that short sleep duration was associated with higher odds of inadequate hydration in and relative to sleeping 8 hours.
“People who reported that they regularly slept for six hours or less each night were 16–59 per cent more likely to be dehydrated than those who slept for 8 hours a night. The study found no association with getting nine or more hours of sleep per night,” Rosinger said
While commenting on the findings, the Rosinger said, “If you are only getting 6 hours of sleep a night, it can affect your hydration status. This study suggests that if you are not getting enough sleep and you feel bad or tired the next day, drink extra water,” he submitted.
