Scientists have found through a study that less sleep during night – or in other words sleep apnea – could lead to dehydration.
According to the study published in journal Sleep, those who sleep for less than six hours a night could be at risk of dehydration. The study analysed records of more than 25,000 adults in China and the US, who were asked about their sleeping habits and had urine samples taken to look for biomarkers linked to hydration.
For the purpose of the study, the relationship between sleep duration and urinary hydration biomarkers among adults in a cross-cultural context were assessed and compared to reach a conclusion. Researchers found that people who slept six hours a night had significantly more concentrated urine and a 16-59 per cent higher chance of being dehydrated, compared with adults who were getting a regular eight hours of sleep.
Focusing on a hormone called vasopressin, a man-made form of a hormone called “anti-diuretic hormone” and is normally secreted by the pituitary gland which the body releases during the day and the night to manage fluid levels, the researchers concluded that their findings could be linked to the way the body’s hormonal system regulates hydration.
Dehydration can have a negative effect on us – right from mood, cognition and headache, to kidney function, dizziness and physical performance. Looks like, apart from keeping yourself well hydrated with fluids and salts, it is always a good idea to sleep in for a few extra hours, preferably with a glass of water on your bedside.
