THE BODY requires a certain amount of heat, but beyond
definite limits, insufficient or excessive amounts are injurious. The local
action of excessive heat causes burns or scalds, and on the other hand, undue
cold causes chilblains, frostbite, and congelation. Thresholds of tolerance
exist in all body structures sensitive to electromagnetic vibrations of other
frequencies such as x-rays, radium rays, and ultraviolet rays. The eye, which
is sensitive to vibrations within the component of the spectrum known as
visible light, is an example of a special sense organ which has similar limits.
The skin, which is exposed to so many external physical forces, is more subject
to injuries caused by them than any other organ.
