Question

Give biological reasons for the following statements:
There is frequent urination in winter than in summer.

Answer 1

The various ways in which the fluid or liquid is flushed out of body are urine, stool, perspiration and breath. During summer, the temperature is high. Hence, majority of water is lost from the body by means of perspiration. As a result, less water is flushed out from the body by the means of urination. However, during winter, there is very less perspiration due to low temperature. Hence, maximum water is flushed out through urine.

Thus, there is frequent urination in winter than in summer.
