Hi! Can you tell me how to get rid of heat bumps? I've been out in the sun a lot.

Heat rash. Heat rash is caused by the build up of sweat from the glands under the skin. The "treatment" is to (1) avoid heat and sweating as much as possible. Being out in the sun a lot, as you say you are, is NOT helpful. (2) Let skin air-dry instead of using towels or cloths; (3) loosen clothes and don't wear clothes that are "skin-tight" like neoprene or lycra; (4) avoid lotions which block the glands.
