why does cold weather make you wanna pee?

 title: 'A Scientist Explains Why Being Cold Makes You Need to Pee More'

Cold weather can increase the urge to pee due to two main physiological responses. First, in winter, people typically sweat less, leading to more fluid being excreted as urine since the body loses less through perspiration. This results in increased urine output as the body maintains hydration levels indoors where water sources are readily available[1][3].

Additionally, cold weather triggers 'cold-induced diuresis,' where blood flow is directed away from the skin to conserve heat, increasing blood flow to the kidneys. This heightens urine production as more blood is filtered[2][3]. Furthermore, cold can cause pelvic floor muscle tension, leading to more bladder spasms, intensifying the need to urinate[2].
