How hot is too hot to exercise outdoors? Ninety degrees. And if the humidity is greater than 75 percent, don’t even think about it. That, at least, is the advice offered by the Fitness Jumpsite, which reprinted the opinion offered by IDEA, which is for some reason the acronym of the International Association of Fitness Professionals. Want more proscription? Here are three more "don’ts" from the Fitness Jumpsite.
- Don’t participate in competitive events, such as 5K runs,
during the hottest part of the day. In warmer climates, make sure
you complete your runs early in the day. - Don’t participate in strenuous swim workouts in heated pools during the summer. Even though you are in the water, you can
still become dehydrated and overheated when swimming. For
hard swim workouts, the water temperature should be 75 to 78 degrees
F ideally, and no more than 80 degrees F (about 26.6 degrees Celsius).
Make sure you drink a steady supply of liquids. - Don’t keep exercising if you feel dizzy, faint and/or nauseous. If you do not rest in the
shade and drink water until you recover, you risk developing
heat stroke, an even more serious condition than heat
exhaustion. Don’t exercise when the air pollution index is
high A health advisory is normally issued at .15 parts per
million (ppm) on the pollutant standards index. If a health
advisory is issued, anyone with any type of respiratory or heart
disease should stay inside until the advisory is lifted.
