  • Air, trying to find new ways to protect students who are training outside.

  • Some are turning to something called the wet bulb globe temperature.

  • It goes beyond the heat index, taking into account sun angle, cloud cover and wind speed.

  • Traditionally, people often use the heat index.

  • This is fine for normal everyday activities such as gardening or taking kids to a park, because most of those activities don't involve intense exercise.

  • Quite.

  • When was the last time you ever saw an entire practice done in the shade?

  • I don't think that happens.

  • Never so that's just that wet bulb Globe temperature also takes into account the sun angle, cloud cover and wind speed, which is why this method is much better at monitoring student at much more detail.

  • So what can you do to help prevent heatstroke and other heat related illnesses, The CDC says you can wear loose fitting lightweight clothing, stay hydrated, protects against sunburn with SPF and take it easy during the hottest parts of the day.

  • It's also important to know the signs of heat stroke.
