Heat exhaustion can result from spending too much time in the
heat and occurs when perspiration leads to excessive loss of
fluids and electrolytes. Even when not in direct sun, a person
can lose too much fluid by staying outdoors too long on a hot
day or spending too much time in an overly hot house or car.
Symptoms of heat exhaustion include: - Severe headache - Cool,
clammy skin - Heavy perspiration - Shallow breathing - Muscle
tremors, cramping If symptoms occur: - Lay the person on their
back in the coolest nearby place - Loosen any tight clothing -
Lower head slightly - Raise the feet - Get medical attention
immediately Heat stroke is more serious than heat exhaustion and
is caused by overexposure to direct sunlight or excessive heat.
Even sitting or lying too long in the sun can cause heat stroke,
which is a medical emergency that can result in death. If you
suspect heat stroke, call 911 or a local emergency number
immediately. - Red, dry face - Skin hot to the touch - Body
temperature of 105 degrees Fa
