What is the main cause of heat stress?
Causes of heat exhaustion include exposure to high temperatures, particularly when combined with high humidity, and strenuous physical activity. Without prompt treatment, heat exhaustion can lead to heatstroke, a life-threatening condition.
What factors cause heat stress?
Environmental factors that can contribute to heat stress besides high ambient temperature are low convection currents, high humidity, low evaporative loss, and high insulation levels around the body. Acclimatization is defined as the time needed for physiological adaptation to extreme temperature changes.
How does heat stress affect the body?
Heat stress is heat-related illness caused by your body's inability to cool down properly. The body normally cools itself by sweating. In such cases, a person's body temperature rises rapidly. Very high body temperatures may damage the brain or other vital organs.

Cool the person's entire body by sponging or spraying cold water, and fan the person to help lower the person's body temperature. Watch for signs of rapidly progressing heatstroke, such as seizure, unconsciousness for longer than a few seconds, and moderate to severe difficulty breathing.
What is heat syncope?
Heat syncope or fainting is a mild form of heat illness that often results from physical exertion when it is hot. It occurs when your body, in an effort to cool itself, causes the blood vessels to dilate to such an extent that blood flow to the brain is reduced.
