Why do you always want to go to the toilet when the weather is cold?

1, there is little or no sweating in cold weather, and the water originally excreted with sweat is excreted through urine, which is just one of the reasons why there is more urine in cold weather.

2. When the weather is cold, the metabolic rate of the human body is enhanced, and the fat and carbohydrate stored in the body are consumed to obtain more calories. Metabolites are carbon dioxide and water, and water is excreted through urine.

3. When the weather is cold, in order to keep the internal organs warm, the human body automatically regulates the contraction of capillaries on the body surface to reduce heat dissipation, and blood flows back to the internal organs, so that the total blood volume in the human body is reduced, and the water in the reduced blood is discharged through urine.
