I sweat excessively when I am in Walmart Stores. Iknow this sounds weird. This affects only my sclap, but by the time I leave the store, my hair looks like I have just stepped out of the shower. Other parts of my body do not sweat heavily, but I do feel hot. I am not under pressure nor am I nervous or jittery; I just can't wait to get out of the store to cool down. I have not noticed this in other stores, but I do find restaurants and other places to be overheated, but I seem to adapt after being there for a while. I am fine in my home (78 degrees) and have not noticed this problem elsewhere (church, etc.). Does this possibly have to do with the type of heating/air conditioning there?
