Understanding wet bulb globe temperature to discern heat riskThis week, the UIL announced new heat safety protocols for high school athletes. The wet bulb globe temperature is similar to the heat index in that it's a way to quantify the impact of the heat on our bodies. The UIL has listed specific precautions for high school athletes based on the wet bulb globe temperature. Another important note on the wet bulb globe temperature is that the final value will be lower than the air temperature, which is opposite of the heat index value. Something to keep in mind when assessing heat risk using the wet bulb globe temperature.
