Dehydration can happen when the body's fluids are low. It can be life threatening, especially to babies, children and the elderly.

The U.S. National Academies of Sciences, Engineering, and Medicine determined that an adequate daily fluid intake is: About 15.5 cups (3.7 liters) of fluids a day for men. About 11.5 cups (2.7 liters) of fluids a day for women.

As a general rule, you can use this simple calculation. Water (in litres) to drink a day = Your Weight (in Kg) multiplied by 0.033. For example, if you are 60kg, you should drink about 2 litres of water every single day. At 90kg, you'll around about 3 litres of water.
A good rule of thumb is to drink 33ml per kilo of body weight. For example, if you weigh 55kg, you should drink 1.8 litres of water per day (0.033 x 55 = 1.815); if you weigh 90kg, you should drink 3 litres of water per day (0.033 x 90 = 2.97).
