Does the presence of large amounts of water in the body help keep body temperature stable? exp
The answer is yes.
Here, the high value of specific heat capacity of water helps.
Drinking water helps regulating the body temperature during winter (extreme cold) as well as during summer.
I remember, schools had made it mandatory for students to dring water after every period during a summer time when the atmospheric temperature was too high and students used to faint often. The water treatment was very effective and the no. of students fainting due to high surrounding temperature decreased significantly.
If we consider the earth system also. it can be seen that the climate is moderate near water bodies.
Further, it is the abundance of water on earth which makes it a planet suitable for the existence of life.
