since it continues to be very hot these days, this is info people need.
HEAT EXHAUSTION
feeling faint or dizzy
excessive sweating
cool, pale, clammy skin
nausea or vomiting
rapid, weak pulse
muscle cramps
treatment: get to a cool, air conditioned place. drink water if fully conscious. take a cool shower or use cool compresses. (i suggest using them around your neck or on the inside of your wrists, where the blood vessels or arteries are close to the surface.)
HEAT STROKE
throbbing headache
no sweating
body temperature above 103 F (39.4 C)
