That's why you don't get enough sleep

Many people do not get enough sleep, and a recent study is claiming that the average is just six hours of sleep in Britain.

The reasons for sleepless nights vary and are often related to psychological matters, but the study states that there may be a lack of water during the day for sleep deprivation at night.

According to research by academics at Penn State University, Pennsylvania, people sleeping for six hours a night had the most concentrated urine and were more dehydrated compared with those who regularly slept eight hours a night, which is the recommended time.

The study included more than 20,000 adults in the US and China, authors concluded that links between sleep quality and hydration are in harmony with good sleep.

This study suggests that if you're not sleeping enough, and you feel bad or tired the next day, drink additional water” said lead author Asher Rosinger, assistant professor at Penn State.

Dehydration may have a number of undesirable effects on the body, such as vertigo, sleepy feeling, and dark, hard - smelling urine.

The most visible way to stay hydrated is to drink plenty of fluids throughout the day and avoid or limit such beverages as caffeine, tea, and alcohol that can get your body drunk.

But when it comes to how much water he should drink every day, advice is contradictory, with some experts suggesting up to four liters, while others say two.
