Heat Cramps
Heat cramps are the result of an
imbalance in the body fluids caused by vigorous activity, dehydration and
high temperatures.
The body loses more fluids than it is
replacing. This fluid debit causes muscles to lose their vital electrolyte
balance (complex salts), thus causing muscular contraction (cramps).

exertion).

and/or abdomen).
