It's cold. What's with the pee?

When it is cold, there is more urine, which may be related to factors such as temperature regulation, antidiuretic hormone reduction, and increased drinking water.

1. Temperature regulation

When the ambient temperature drops, the human body maintains body temperature through different physiological reactions. One of the important reactions is vasoconstriction, which reduces body heat dissipation and thus maintains body temperature stability. Vasoconstriction also leads to increased blood flow to the kidneys, stimulating kidney urination and promoting excess fluid in the body to be discharged through urine.

2. Antidiuretic hormone is reduced.

When it is cold, the secretion of antidiuretic hormone in the body usually decreases, and the main role of antidiuretic hormone is to reduce urine production and make urine more concentrated. Therefore, when antidiuretic hormone is reduced, urine production increases, resulting in more urine.

3. Drinking water increases.

In cold weather, people often unconsciously increase the number of times to drink hot water, which is a body function, and the increased number of drinking water will lead to increased urine production, resulting in more urine.
