Why do people frequently urinate in cold weather?

on an average temperature day, the body usually produce about 1 to 2 quarts of urine. Cold weather will result in the body needing to filter more blood than normal as blood is rushing to the vital organs at a higher frequency. This results in you having to pee more often.

The inability of our body to sweat, as it does not have enough energy to cause sweating. The muscular contraction caused by the cold, particularly of the bladder, which causes the production of more urine.
