Why do you pee so much in winter? What is this phenomenon related to?
First, because of the arrival of winter, the weather is cold and it is not easy to sweat. Because there are water, soup, fruits, vegetables and so on. Those who eat in, in the process of human digestion, the human body can't absorb so much, and don't sweat, so they can only be excreted through defecation, so they will urinate more than in spring and summer.
Second, it depends on one's physical fitness. Some people have frequent urination, which may be caused by something wrong with the body or kidney, because kidney deficiency can lead to frequent urination, frequent nocturia, backache and so on. If it's a problem in this area, it's good for you to consult a doctor or have a targeted examination.
In the cold state, the skin blood vessels contract to the maximum extent, and the blood flow can be reduced to 20-50 ml/min, or even lower.
In this way, in an obviously cold environment, especially when the temperature drops suddenly, the blood circulation stimulating the skin is obviously reduced, and a large amount of blood will be transferred to the central circulation in the deep layer of the body, and the brain will receive the signal of a sudden increase in blood volume; At the same time, blood pressure will also rise-this is also the main reason for the frequent occurrence of cardiovascular and cerebrovascular diseases in winter.
The increase of blood volume and blood pressure will trigger the feedback regulation mechanism of human body to restrain this upward trend.
This is mainly achieved through the regulation of body fluids by the kidneys.
The specific way is that the increase of blood volume and blood pressure inhibits the production and secretion of hypothalamic antidiuretic hormone.
Diuretic hormone is a 9-peptide hormone secreted by hypothalamus, which mainly acts on the distal convoluted tubule and collecting duct of kidney, increasing water permeability and thus increasing water reabsorption, so it is a "water-retaining" hormone.
