Q
What does your body do to reduce energy loss?
A
The blood vessels that supply your skin capillaries constrict reducing blood flow and energy lost through radiation through the surface of the skin. Sweat production is reduced. You may shiver and this is when your muscles contract and relax rapidly. This requires a lot of respiration which releases more energy and raises your body temperature.

Q
How does your body cool you down when you are too hot?
A
The blood vessels that supply your skin capillaries dilate which always more blood to flow through your capillaries so more energy is lost via radiation. Your rate of sweating also goes up, and this cools you because the sweat evaporates.
