Your body is made up of about 90 % water. Why is this important to maintain your body temperature during the summertime and wintertime?

Explanation:

It is important that we maintain an optimum temperature for the enzymes in our body (around 37 degrees celsius). If it's too hot, our enzymes will denature and will become inactive/lose their function. If it's too cold, the enzymes will too become ineffective (their function will slow down too much).
