Frequent urinating when cold?

COLD DIURESIS (frequent urination) 

When you feel cold and have cold feet and hands do you have frequent toilet visits? Why? The body protects vital organs from cooling by reducing the blood flow to the outer layers of the body. More warm blood is kept in and around the body’s core, increasing the volume and pressure at the same time. Unfortunately, the brain may perceive this as an unnecessary increase. It instructs the kidneys to extract some of the fluids from the blood and shed it as urine.
