When do you think you should drink 
more water?
All plants, animals, and humans need water 
to live. That’s because our bodies need water 
for nearly everything they do. Our blood needs 
water to move around the body. Our stomachs 
need water to digest food. More than 70% of 
our brains are water, so drinking water helps us 
think better.
When we do sports and when it’s hot, we lose 
water through our skin. This body water is called 
perspiration. We put water into our bodies when 
we drink and eat. When we lose more water 
than we put into our bodies, we feel tired and 
we sometimes have a headache. That’s why it’s 
important to drink 6–8 glasses of water a day.
