Why Do I Have To Pee More When It's Cold?

Did you ever come inside from the cold and almost immediately need to urinate?

When it is cold your body tries to keep your "core" warm.  The core is your heart, lungs and brain.  The way the body does this is by constricting blood vessels in your extremities like your hands and feet.

The end result is you have the same amount of blood circulating in a smaller area.  This is good for keeping your core warm but your kidneys sense too much fluid so they start making more urine.

By the time you get inside you might have a very strong urge to urinate. This is normal.

If you find that you are more thirsty later that is also normal.  Your body wants to replace the water it lost in that extra urine you made.

So now you know.
