July 5, 2022, (Winnipeg, MB) – After a longer than normal winter and cold, wet spring, many Manitobans are ready to embrace the summer heat. If you’re working outside in the heat or indoors without air conditioning, however, it should also mean taking steps to protect your health. High temperatures and elevated humidity can lead to serious illness, including heat exhaustion and heat stroke, and in extreme cases, even death.Hot weather conditions affect how well we regulate our body temperature. Hot air, sunshine and hot surfaces increase our temperature as does high humidity. Combining these factors with physical activity causes our bodies to produce even more heat. Both workers and employers need to be aware of the risks of high heat and humidity.
“Both employers and workers can take measures to protect against the dangers that hot weather presents, preventing illness and avoiding lengthy work delays,” says Jamie Hall, Chief Operating Officer of SAFE Work Manitoba. “We recommend becoming knowledgeable about the signs of heat illness and aware of what is happening with workers as temperatures climb.”
