Final stages of acclimatization to heat are marked by increased sweating and reduced salt concentration in the sweat. The most important safeguard to the health of the athlete is the replacement of water. Water must be on the field and readily available to the athletes at all times. It is recommended that a minimum of 10 minutes be scheduled for a water break every half hour of heavy exercise in the heat. Check and be sure athletes are drinking water.
Cold water is preferable.
Drinking ample water before practice or games has also been found to aid performance in the heat. Salt should be replaced daily. Modest salting of foods after practice or games will accomplish this purpose. Salt tablets are not recommended. The greater the humidity, the more difficult it is for the body to cool itself.
