Now, what happens if we decrease our temperature? Let's suppose our cells are now exercising less than they normally do. And what that means is they are producing less thermal energy. And so the temperature within the blood plasma of the capillary actually drops. And what that means is if the cells are exercising less, they need less oxygen. And so the hemoglobin will be less likely to release and unload that oxygen and more likely to actually bind to that oxygen.
