I live in the tropics, even in the dead of “winter” it is in the 90’s at lunch when I usually run. And in the summer, often hotter. I love it, it makes my muscles feel so loose and easy and I feel great after working up a good sweat. I recently spent 2 weeks in a much colder climate and it just about killed me, my body felt so tight and stiff, I had to run for a half hour or so before I started to feel warm!
I do drink plenty of water but can’t help but remember when we were kids and would play in the heat for hours on end with no hydrating except an occasion slurp from a yukky tasting garden hose, and here I am at 65 to tell the tale and still running and playing too!
