Humans are essentially composed of water. Organism’s need for water depends on several factors such as outside temperature, person’s activity level, metabolic needs and age. It also depends on individuals bone density and muscle mass.
All body functions such as breathing, digestion, metabolism, assimilation, elimination and regulation of body temperature, can take place only in the presence of water. Water keeps the acidity and composition of all chemical reactions.
Why your body needs water?
Here’s some facts why your body needs water.
Blood is made up of 80% water and requires water for the formation of new blood cells. Your bones are composed of 50% water and also require water for the formation of new bone cells. Water removes pollutants and toxins from your body – through the lymphatic system, kidneys and intestines.
Drinking water ensure adequate hydration and thereby reduce pain, if present. Water regulates the metabolism, so you need to drink plenty of water, especially if you are of a somewhat heavier build.
Drinking water cleans your skin and makes it glow. This of course does not happen overnight, but regular drinking of adequate amounts of water will certainly show results in long term.
Proper hydration is important. Drink water even if you are not thirsty in order to maintain normal body operation.

Water relieves headache – and headaches are very often caused by dehydration. Drinking water in combination with consuming a lot of fiber will boost your metabolism and enhance slow digestion. Your digestive system needs a lot of water to operate properly.
And last, but not least. Drinking water is one of the best ways to fight obesity. First, because water itself is not caloric. Second – we often think we are hungry, but we are actually thirsty. So before you reach for calorie snacks rather drink a glass of water and maybe you will cease to be hungry.
How much water is enough?
There are different guidelines on how much water should one drink per day. Various international organizations such as World Health Organization WHO recommends different amounts, depending on age and gender. This amount ranges from 3 pints (1.5 liters) to 7.8 pints (3.7 liters) of water per day.
The amount of needed water per day also depends on a person’s geographic location – for example, people that live in Africa should drink more water than people who live in North Europe (temperatures in Africa are much higher than temperatures in North Europe). If you are doing sport this amount is even higher, because while you’re active you lose a lot of water sweating.
In principle, it is necessary to drink 2 pints (1 litre) of water for every 1000 calories consumed. Children require 3 pints (1.5 liters) of water per day and adults require 4 to 6 pints (2 to 3 liters) of water per day. Older people should drink about 5 pints (2.5 liters) of water per day. Pregnant women should drink more water per day – at least 4 pints (2 litres) per day.
