Why You Need to Drink Water

In this educational TED-Ed video, Mia Nacamulli, TED educator, details the necessary role water plays in the human body and how much H20 we actually need to stay healthy.

According to recent studies, the amount of water the human body needs varies between gender, weight, environment and activity levels. On average, women need between 2 and 2.7 liters a day (approximately 11 cups) and men between 2.5 and 3.7 liters (nearly 16 cups). Getting the optimal amount of water helps regulate body temperature, nourish brain cells and can help manage diabetes.
