The human body is composed of 60% water. Each body’s function requires water, such as flushing toxins from the organs, transporting nutrients to your cells, cushioning the joints, and helping the digestion of food. Therefore it is pretty much evident that water is the basic need of the human body to live a healthy life or, let me say, stay alive. If we don’t get enough water, we can be dehydrated, resulting in dizziness, confusion, and even seizures.

But the question prevails that how much water should I drink each day? There is no clear and accurate answer to this question as your daily water requirement depends on various factors such as your size, how much exercise you do, the weather where you live, and other things.

This water comes from the intake of water, beverages, hot drinks and food.
