Great article from the NY Times with detailed research and studies
on what tactics seem to work best in “cooling” the body prior to a run in the summer heat.
I personally have introduced Hot Yoga (90 minute classes) to my workout routine this summer…and not only seen the stretch benefits during/after class but also the ability to adapt to the heat during my runs easier as well!
The takeaway for those to busy to read the full article:
“The upshot of these results is that “you will receive a bigger bang for your buck from acclimating to the heat rather than by temporarily cooling yourself down” with chilled clothing and such…
On the other hand, precooling can be a useful stopgap measure when temperatures suddenly rise and you do not have time to acclimate before a looming competition, he says. “Throw your ice vest and cooling shorts into the freezer” and wear them for about 20 minutes before your event, he advises.
Acclimation demands far more time and planning. During your first workouts in summer heat, he says, reduce the time you spend outside and go at a gentler pace than normal, slowly ramping up your effort as the exertion begins to feel more tolerable, which can require anywhere from four or five days to two weeks, depending on your current fitness and heat tolerance. Be sure to drink plenty of water, too, he says, since you will start to sweat more profusely.”
Try it for yourself! I know I will!
