Water Facts for Humans:

Being dehydrated can zap your energy and make you feel tired -- even mild dehydration of as little
as 1 or 2 percent of your body weight. If you're thirsty, you're already dehydrated -- and this can
lead to fatigue, muscle weakness, and dizziness

Drinking water can help clear up your skin and people often report a healthy glow after drinking
water. It won't happen overnight, but just a week of drinking a healthy amount of water (about 2
litres per day) can have positive effects on your skin

Go into a sporting game dehydrated and you can be sure you won’t be as fast or focused. Being
dehydrated can severely affect your athletic activities, slowing you down and making you less
powerful. Exercise requires additional water, so be sure to hydrate with water before, during and
after exercise

Although a person can live without food for more than a month, a person can only live without
water for approximately one week.

Most mature adults lose about 2.5–3 litres of water per day. Water loss may be more in hot
weather and with prolonged exercise.
