Heat Injuries and Symptoms
|
The following are common types
of heat injuries and their symptoms.
Heat cramps - muscles cramps
of the abdomen, legs, or arms.
Heat exhaustion - headache,
excessive sweating, dizziness, nausea, clammy skin.
Heat stroke - hot, dry skin,
cessation of sweating, rapid pulse, mental confusion, unconsciousness.

To prevent heat injuries while
exercising, trainers must adjust the intensity to fit the temperature
and humidity. They must ensure that soldiers drink enough water
before and during the exercise session. Body weight is a good
gauge of hydration. If rapid weight loss occurs, dehydration should
be suspected. Plain water is the best replacement fluid to use.
Highly concentrated liquids such as soft drinks and those with
high sugar content may hurt the soldier's performance because
they slow the absorption of water from the stomach.

To prevent heat injuries,
the following hydration guidelines should be used:
Type of drink: cool water
(45 to 55 degrees F).
Before the activity: drink
13 to 20 ounces at least 30 minutes before.
During the activity: drink
3 to 6 ounces at 15 to 30 minute intervals.
After the activity: drink
to satisfy thirst, then drink a little more.
