Into the winter, the temperature in the north is gradually falling, many patients to the clinic are described, they are usually quite good, a winter weather is cool, this urine is frequent. Why do men love frequent urination in winter? First of all, the normal adult daily urinary output of 1000 to 2000 ml, more than 2500 ml belongs to polyuria. The average daytime urination 4 to 6 times, 0 to 2 times at night after going to bed, more than the above number of times, generally considered to be frequent urination. Our ancient people have long observed this problem, “Nei Jing” has the cloud: “days of cold is coupled with closed, gas and moisture can not be, the water under the bladder to stay in the bladder, then for the drowning and the gas”. It means that frequent urination in winter is the cold weather, the lack of yang qi, bladder qi unfavorable performance. The human body in the case of the same amount of drinking water, summer can have sweat evaporation and urination two ways to discharge water, winter sweat evaporation is reduced, the amount of urine will increase accordingly. In addition, as far as men are concerned, the cold weather in winter can increase sympathetic excitability, prostate gland contraction, glandular ducts and blood vessel dilation, resulting in increased intraurethral pressure, which in turn will aggravate the stagnation of prostate fluid, making symptoms such as urinary frequency and urgency more pronounced. If persistent polyuria occurs, diseases caused by secretory metabolic disorders should be considered, including pituitary dysuria, diabetes mellitus, and primary aldosterone hyperintensities. In addition, prolonged frequent urination with urinary pain and urgency should be considered inflammatory stimuli such as cystitis, urethritis, or urinary stones. Therefore, don’t carry on when you feel the coolness, pay attention to the lower body to keep warm, put on the autumn pants earlier, keep the warm environment locally can make the prostate drainage, reduce the muscle tissue contraction, make the prostate congestion, edema state is restored, so as to alleviate the symptoms of frequent urination. If the symptoms of frequent urination are obvious and last for a long time, you should consult a doctor to find out the reason and prevent the delay of the condition.
