A normal person urinates about four times a day, and it may be a physiological phenomenon to urinate more in winter than in summer. Because of the cold weather in winter, the body’s blood vessels and the muscles that govern the nerves may contract, which can lead to excessive urination. If the urine is accompanied by painful urination and urgency, it may be a pathological phenomenon, and you should seek medical attention to find the cause with the help of urine routine and ultrasound examination. 1. Physiological phenomenon: Compared to summer, if you drink the same amount of water, the cold in winter can easily lead to muscle contraction, and the bladder will be more sensitive to the reflexes of nerve regulation, and the feeling of urination will occur. In addition, the cold will also lead to a certain degree of reduced sweating, resulting in more urine, generally not accompanied by other physical discomfort. It is recommended to pay attention to warmth in winter to avoid cold attack on the bladder area; 2. Pathological phenomena: If you have more urine in winter combined with symptoms such as urinary urgency, painful urination and bifurcation of urine, you should not only pay attention to warmth, but also go to the hospital for urinary routine, ultrasound and other examinations, which may be a urinary tract infection, urinary stones, urinary tumors and other diseases that require active treatment.
