Does the average person's urine volume increase or decrease when the weather is cold?

People's urine output is generally much colder. When the weather is hot, the human body sweats more, and the water in the body is lost more. The renal tubule's ability to reabsorb water and sodium ions is enhanced, so as to keep the balance of water and salt in the body, and don't let too much water be discharged from the urine.

Normal people urinate about 1-2 ml per day, with an average of about 15 ml. Because normal people have about 35-5g of metabolites and salts that need to be excreted through the kidneys in the form of urine every day, the minimum amount of water needed to dissolve these solid substances is about 5ml, so everyone needs to excrete at least 5oml of urine every day. Therefore, it is medically stipulated that when a person's urine volume exceeds 25 ml in a whole day (24 hours), it belongs to polyuria; When the daily urine volume is less than 5 ml, it belongs to oliguria; When the daily urine output is less than 1ml, it belongs to anuria.
