Is the only reason air moving over your body caused by a fan or breeze feels cool because of increased evaporation of moisture from your skin? Or does it blow air being warmed by your skin away from your body to be replaced with relatively cooler air? Also, does air movement also produce some amount of heat, albeit very small? I wonder this because it seems like the air movement would increase the kinetic energy of air against your body and maybe also raise the air pressure as well. Is heat produced as well as mitigated by a fan?
