Chop up half-a-pound of tomatoes, one pound of cooking apples, six small onions, a halfcupful of mint leaves, one-and-a-half cupful of seeded raisins, and three small sweet Sunburn Season is Here Sunshine is composed of three kinds of rays—(1) the infra-red or thermal rays, which furnish heat, (2) vie visible or chromatic rays, which provide light, and (3) the ultra-violet or actinic rays, which are not concerned with light or heat, but with chemical actions. It is these ultra-violet rays that are both the cause of sunburn and the foundation of sun healing or heliotherapy.
Sunburn is the result of excessive exposure of the skin to ultra-violet rays. It can occur equally on dull days and bright days. Brunettes are more resistant to sunburn than blondes, because the natural pigment of their skins gives them some measure of protection. Most individuals can acquire a good protective pigment by exposing themselves to doses of sunshine, carefully graduated and spaced.
