Does the amount of sweat produced while exercising affect overall performance?
As part of health improvement since having diagnosed with diabetes, I'm trying to do walks with the treadmill as a stepping stone for exercising. But when I do so I heat up pretty quickly and sweat a lot so I try to use a fan to cool myself off while doing the exercise. I notice I definitely last a bit longer on the treadmill with the fan but I'm wondering whether that would affect the exercise in any way.
