Re: [RC] eating at rides//cold diuresis-Lynne - Barbara McCrary

I cannot drink orange juice, cocoa or tea before a ride. Between nerves and cold, I have enough problems with needing to go early in a ride (like 3 miles or less.) Thank you Beverley for explaining the physiological reason. It helps to know I'm not the only one, and why.

Ah, you're describing physiological process of "cold diuresis." It's the
opposite of sweating, where water is evaporated out the skin. In the cold,
blood is shunted away from the periphery (hands, feet, skin, superficial
tissues) and into the central regions of the body, including the kidneys.
When the kidneys get more blood, they produce more urine.
