Why is it cold, frequent urination, urgency?

When the weather is cold, it is easy to show frequent urination and urgent urination symptoms. Possible reasons: 1. From the perspective of Western medicine, when the weather is cold, the skin and respiratory tract evaporate less water, and the body retains relatively more water. After drinking water, the blood volume increases, and the blood volume filtered by the kidneys also increases. At this time, the filtration ability of the kidneys is relatively strengthened, and the urine produced is relatively large. Therefore, it is easy to show frequent urination symptoms after drinking water in cold weather, which may be related to increased kidney filtration. When the weather is hot, the skin and respiratory tract should evaporate more water, then the blood flow through the kidney is relatively cold, so the frequency after drinking water is not obvious when it is hot, but it is obvious when it is cold. 2. From the point of view of traditional Chinese medicine, cold weather, cold nature, cold nature, clear and long, so that the kidney's ability to withdraw is relatively reduced, resulting in clear and long urine. When the weather is cold, kidney yang qi is slightly insufficient, so no water intake causes increased urine and frequent urination, especially when the age increases.
