Who is affected? Anyone exposed to hot and humid conditions are at risk of heat illness, especially those doing heavy work tasks or using bulky protective clothing and equipment. Some people might be at greater risk than others if they have not built up a tolerance to hot conditions.
What is heat illness? The body normally cools itself by sweating. During hot weather, especially with high humidity, sweating isn't enough. Body temperature can rise to dangerous levels if precautions are not taken. Heat illnesses range from heat rash and heat cramps to heat exhaustion and heat stroke. Heat stroke can result in death and requires immediate medical attention.
How can heat illness be prevented? Remember three simple words: water, rest, shade. Drinking water often, taking breaks, and limiting time in the heat can help prevent heat illness. Gradually build up to heavy work in hot conditions. This helps you build tolerance to the heat - or become acclimated. Gradually increase workloads and allow more frequent breaks during the first week of being outdoors. Also, it's important to know and look out for the symptoms of heat illness in yourself and others during hot weather. Plan for an emergency and know what to do - acting quickly can save lives!
