Heat stress is a group of disorders that occur following excessive heat exposure. These range from heat cramps all the way to heat stroke, which is a life-threatening condition.
FACTORS WHICH LEAD TO HEAT STRESS INCLUDE: - increased air temperature and humidity
- lack of physical conditioning or obesity
- hard exercise and dehydration
- heart disease and other chronic illnesses and
- alcohol and other drug consumption, including the use of some prescription medications
The signs of heat stress include thirst, headache, nausea, dizziness, muscle cramps, and weakness. TO TREAT HEAT STRESS, YOU SHOULD: - have the person stop exercising and lie down
- remove the person to a shady or cool place
- spray the person with cool water, or immerse them in water
- give the person plenty of fluids to drink such as fruit juices, sports drinks, or caffeine-free soft drinks (Water with one-quarter teaspoon of salt added per litre may also be given.)
Treat heat stress properly at this stage, or the person may develop heat stroke. Heat stroke is a serious emergency. THE SIGNS OF HEAT STROKE INCLUDE: - confusion, loss of judgment, fainting, or loss of consciousness
- very hot, dry skin temperature (When seen in young, exercising adults, sweating may be present.)
- body temperature of 40 degrees Celsius or higher
- convulsions or seizures
IF THESE OCCUR OR A PERSON DOES NOT RESPOND ADEQUATELY TO CONSERVATIVE MEASURES: - call for help by dialing 000
- spray the person with cool water, and use a fan to cool them
- place ice packs on the person's head, neck, groin, and under the armpits
- often, emergency fluids given into a vein will be needed
