Lost in the Desert:

1. Heat stroke: A severe condition caused by impairment of the body's temperature-regulating abilities, resulting from prolonged exposure to excessive heat and characterized by cessation of sweating, severe headache, high fever, hot dry skin, and in serious cases collapse and coma.

First degree burn: A mild burn that produces redness of the skin but no blistering.

Electrolytes: Any of various ions, such as sodium, potassium, or chloride, required by cells to regulate the electric charge and flow of water molecules across the cell membrane

Melanin: Any of a group of naturally occurring dark pigments, especially the pigment found in skin, hair, fur, and feathers.
