We all know that dehydration is something that happens in the summer. But it can also happen in winter! 

Humans, like all mammals, have a survival mechanism that contracts blood vessels when it is cold in order to maintain a constant body temperature. This causes an increase in blood pressure. To reduce it, the kidneys mobilise the production of more urine. Result? Less blood in the veins and arteries and more visits to the toilet!

In addition, the sebaceous glands located just below the surface of the skin tend to become relatively inactive in winter and produce less moisture than usual.

As we all want our shower to be hot, this unfortunately leads to an excessively dry skin. To maintain moisture, shower with lukewarm water , because the hot water destroys the important lipid layers that maintain skin moisture. 

As for the amount of water you should consume daily, the golden number is 6 - 8 glasses. 

Also, as recommended by experts:

- Avoid beverages with caffeine or alcohol that have a diuretic effect

- Consume water-rich foods such as fruits, vegetables, soups

- Drink water before, after and during exercise, even if you don't feel you need it.

- And remember to drink a glass of water before every meal

A well-hydrated body efficiently metabolizes fat to use it as energy and controls appetite better.
