Here in Massachusetts, as in much of the country, we’re heading into a stretch of sweltering days. With that in mind, we’re going to postpone the Worst Dressed poll and talk about the heat.
You already know that during exercise your core body temperature can rise by a couple of degrees. Your body copes with this increase by sweating. As the sweat evaporates, you cool down.
When humidity is high, the air is too saturated for your sweat to evaporate quickly. The higher the humidity, the hotter you’ll feel, and the more dangerous any given temperature will be.
How do you know when it’s too hot to play outdoors? You need to find out the heat index, or the “real feel” temperature, a combination of actual temperature and humidity.
