One of the biggest hazards of heat waves is to health. People of all ages can suffer the effects of a heat wave, but the ill, very young, elderly, or overweight tend to be affected more severely. Even though warnings and advisories are given, people often don’t follow the guidelines in areas as basic as drinking a lot of water. When the human body sweats in large amounts, salt and other minerals are lost which have to be replaced. Exercising during a heat wave is never a good idea; but even with regular exertion, it’s advised to replenish the body’s supply of electrolytes.
Heat exhaustion, which shows itself in symptoms such as vomiting, diarrhea, headache, nausea, etc. can lead to dehydration if not taken care of right away. Generally a patient must have their fluids replenished along with salt. Rest is needed and patients are advised to stay out of the heat. Heat stroke can be fatal if not treated immediately.
Heat rash, heat cramps and heat syncope are other results of heat waves. Of all the natural phenomena, heat waves are considered one of the most fatal. Deaths related to heat are often hard to count because it affects those already run down, elderly, or sick. Those who can’t afford air conditioning or other cooling devices are more likely to suffer. Psychological damage should not be underestimated; violence often increases during these periods of time.
