Why is it when the weather's cold, you tend to have the urge to pee more often?

This morning while i was sitting in the bus on the way to work, i thought of this when i had the sudden urge to pee. My ride usually takes an hour and im not the type who feels the urge to pee often. But this morning, the bus i took was so cold and i havent seated more than 30 minutes when suddenly i had to really go. This isnt the first time i have observed it and i wonder, is there an explanation behind this or is it just me? :)

I guess there is a more scientific explanation to that as in summer you sweat more and in this way the body losses its water and thus you dont have to loose it with that activity and in winter you dont sweat that much thats why you gotta do that very often to loose the extra water inside of body.

Further more you get periphery vasoconstrition in which blood is divertion to internal organs including the kidneys, hence you get increase bl0od flow to the kidneys resulting in increase urine output.

I notice this when it is colder as well. Especially at night. I normally sleep all night without having to get up to pee, but as soon as it gets cold and you really dont want to get up in the night to pee I seem to need to two or three times a night!!! I hate getting out of my warm bed, walking on cold tiles and then having to sit on a freezing toilet seat!!! I would also like to know WHY!!! My butt is sick of freezing at night!Lol
