Whether walking to your car or performing a strenuous task at the jobsite, your body is always working to maintain a balance and sustain its core temperature. And because our bodies are constantly exposed to elements that increase body heat and deplete hydration levels, workers must be extra careful when working in extremely hot or extremely cold conditions.
