Wednesday’s Jaremaga was about staying safe in hot, humid weather. There is a way to measure how dangerous this kind of weather is. It is called the WBGT, and it stands for Wet Bulb Globe Temperature. It was developed by the American military to keep soldiers safe from heatstroke during training exercises. The number comes from the air temperature, the humidity, the strength of the sun’s rays, and the effect of the wind. I found out recently that Japanese schools use the WBGT to decide whether it is safe for the students to do sports. If it is 31 degrees or above, children in Japan are not supposed to exercise outside. You can easily check the WBGT by installing an app on your phone. Just search for WBGT on the app store.   (132 words)
