Death is even possible. This week's Tail Gate Safety Topic discusses ways to prevent heat stress and how to recognize the symptoms of a number of heat-stress conditions. Heat stress is commonly associated with warm weather. It's true that warm weather increases the number of heat-stress injuries and illnesses. Warm weather isn't the only cause of heat stress, though.
Heat stress can occur any time the surrounding temperature is elevated.
Even if the weather is cool, you may work in warm areas, indoors or out. Be alert for conditions which could cause heat stress and take precautions to prevent it. Acclimatization processes involve gradually increasing the amount of time you spend working in a hot environment. This gradual increase allows your body to properly adjust to the heat. Keep in mind, though, even if you're already acclimatized, conditions can change which stress your body even more.
