Dangers of the Sun - ContinuedFirst-Aid Treatment for Heat Stroke:1. Emergency medical help should be summoned. 2. Wrap victim naked in a cold, wet sheet which should be kept continually wet.

DehydrationDehydration is a condition in which a person’s water content has fallen to a dangerously low level. Water accounts for approximately 60% of a man’s weight, and 50% of a woman’s, and the total water content must be kept within fairly narrow limits for healthy functioning of cells and tissues.
The concentration in the body’s fluids of mineral salts and other dissolved substances must also be kept within a narrow range. In many cases of dehydration, salt will have been lost as well as water. Symptoms of DehydrationThirst, dry lips, mouth and tongue are the most common symptoms. Victim may experience an increase in heart rate and breathing, dizziness, confusion and eventual coma. Skin will appear dry and without elasticity. Urine will be in small quantities and dark-colored. If salt depletion also occurs there may be lethargy, headaches and cramps. Treatment of DehydrationImmediate fluid and salt replacement should be initiated. An intravenous replacement may be required in conjunction with blood tests that will monitor the balance of water and salt in the bloodstream.
