Heat stress problems can be controlled provided certain precautions are taken. Along with physical conditioning the factor of acclimatization to heat is important. Acclimatization is the process of becoming adjusted to heat and it is essential to provide for gradual acclimation to hot weather activities . It is necessary for a student to exercise in the heat in order to become acclimatized to it. Final stages of acclimatization to heat are marked by increased sweating and reduced salt concentration in the sweat.
Younger athletes take longer periods of time for acclimatization.
The most important safeguard to the health of the student is the replacement of water. Chilled water must be available on-site and in unlimited quantities . Periodic enforced drinking beyond the amounts required by thirst should be assured. Only plain chilled water should be used for fluid replacement during rest periods. Sweetened drinks should not be used since they impair transit of water from the stomach to small intestine where absorption occurs.
