The heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature. This has important considerations for the human body’s comfort. When the body gets too hot, it begins to perspire or sweat to cool itself off.Advertisement

take caution to protect yourself and others from the impacts of
the upcoming heat wave. If spending time outdoors, try to limit
strenuous activities and wear loose-fitting, light-colored
clothing. If working outdoors is necessary, stay hydrated, and
take breaks in the shade as often as possible. Look before you
