Why does cold weather increase the frequency of urination?

It is a normal physiological phenomenon that people go to the toilet more often in cold weather.

First of all, when the weather is hot, most of the liquid in the body decreases with the elimination of sweat; When the weather is cold, the capillaries on the body surface will contract, sweat will decrease, and most of the water in the body can't be eliminated in time, so the number of trips to the toilet will be more than when the weather is hot.

Secondly, when the weather gets cold and the circulating blood volume increases, it will stimulate the neurohumoral regulation of the body, reduce the secretion of antidiuretic hormone, increase the amount of urine and increase the number of urination.

Of course, if there are symptoms such as dysuria and urinary incontinence, cystitis should be considered and treated in time.
