Even lack of sleep dries our body


Those who sleep too little like dehydration

Many adults only sleep six hours a night – that's too little, according to a number of studies. The recommended sleep duration for adults must be between seven and eight hours every day. The team of American researchers is now finding another good reason why they should follow this sleep guide. Apparently, lack of sleep affects hormones and favors dehydration.

Researchers at Penn State University in Pennsylvania found in a recent study that too little sleep adversely affected our hormones that regulate body fluid balance. This is related to the possibility of increased dehydration. The results of the study were recently published in the journal "Sleep".

Sleep well? Then you have to drink more water

If you feel unwell after a short night, this might be the effect of dehydration. The researchers suggest that people who sleep too little should drink more water after a night of sleep deprivation to fight the symptoms of dehydration. "Already from just six hours of sleep per night, your fluid balance can be affected," warned study director Asher Rosinger.

Sleep balance and body water related

The Penn State research team examined the voluntary fluid balance in terms of sleep duration. The team found that participants who slept only six hours had significantly more urine. In addition, short sleep groups were 59 percent more likely to not be hydrated enough than adults who slept regularly for eight hours.

How does lack of sleep affect water balance?

In further research, the researchers found that a certain hormone called vasopressin was responsible for this effect. This hormone regulates the body's water balance. Although released both during the day and night, but as scientists prove, the distribution process is accelerated in the late sleep cycle. "So, if you wake up early, you might lose a window where more hormones are released, which disrupts the body's hydration," Rosinger said in a news release on the research findings.

How to recognize dehydration

According to the researchers, dehydration can affect many systems and functions of the body. Among other things, this can be reflected in perception, mood and physical and mental performance. If such conditions persist for a longer period of time, more serious health consequences such as urinary tract infections and kidney stones are at risk.

Further effects of sleep deprivation

But sleep is not only important for water balance. During sleep, the brain detoxifies and sleep disorders reduce the process, because during sleep, the interstitial space of brain cells filled with brain water expands. This extension is similar to a highway, where waste from metabolism is transported from the brain at twice the speed. This can also be an explanation of why healthy sleep is considered a function of protection against dementia.

However, too much sleep can damage

Too much and too little sleep damages our health. Another study found that people who regularly slept ten hours or longer were at an increased risk of developing metabolic syndrome. This is a dangerous combination of obesity (especially accumulation of abdominal fat), high blood pressure and increased blood sugar and high blood fat levels. (Vb)
