I wonder if he doesn't sweat as much as he should be. My sister's off the track TB was a non-sweater and he'd get super hot in the summers here until he was put on One AC. One AC is a supplement based on the theory of imbalance of dopamine to the nor-adrenaline/adrenaline complex. Dopamine is used first by the brain, then by the cardiovascular system and last by the sweating system. A reduction in dopamine below a certain level allows the well-known vasoconstrictive properties of the nor-adrenaline/adrenaline complex to predominate and reduce the blood carrying capacity of the peripheral vascular system to a minimum, thereby reducing the ability of the sweat glands to function properly. Makes for a very hot horse if they aren't sweating properly ...
