Why is it cold? I pee a lot. Urine at least 12 times the next day. Basically every two or three hours. Is it a disease?

The weather is cold, and the water on the body surface evaporates less. So the frequency of urination will increase. If the amount of urination at a time is relatively large, there is no discomfort in urination, such as incomplete urination and painful urination, and there is no frequent urination at night, which should be a normal physiological phenomenon. If there are symptoms such as dysuria and urinary incontinence, cystitis should be considered and treated.
