The answer to the question why do we need water is known by everybody from children to old people. Nutritionists and doctors are emphasizing the important role of water for the good functioning of the human body. Nutrition and drinking water are so closely linked because water makes up more than 70% of the body’s tissues and plays a role in nearly every body function from regulating temperature and cushioning joints to bringing oxygen to the cells and removing waste from the body. We also need water for our blood to be able to carry nutrients around the body. Without water, our body’s survival time is limited to a matter of hours or days.
Water is eliminated from the body through urine and sweat, and should be replaced though the diet, during the meals or as the thirst dictates. Actually if you feel very thirsty, you are already dehydrated so make sure you are drinking water during all day to avoid this sensation. Other signs of dehydration are: dark coloured urine, headaches, confusion and irritability, lack of concentration. Chronic dehydration can cause a number of health problems, such as constipation and kidney stones.
