Actually I would think that idea is smart.
As Romad stated it is hot and humid. I recall one year that it was 105 plus without the index for something like 3 weeks.Add in the humidity and coming from a state like Maine and if not use to it, not hydrating properly may become a medical issue too.
The ABUs wearing the boots and heavy socks aren't shorts and tee shirts with flip flops either.
I remember moving from NJ to NC in June and I was sweating in the car with air on as we drove into town. Meanwhile I am watching kids playing outside and thinking their folks are nuts. Two weeks later my kids were the ones people thought we were nuts...you get accustomed to it quickly, but by the time your kids are accustomed to it, it will be almost over.
We have lived ever climate zone, and I can tell you only in the South can it rain for 3 hours, and have the pavement dry fifteen minutes later. Only in the south does the humidity and air temp feel worse after it rains. Only in the south do you have more dew on your car in the a.m. than you would in the fall.
Romad,
I thought the baseball caps were worn to absorb all of the sweat. All of Bullet's ball caps have a clear distinct sweat line.
OBTW,
I also learned why riding lawn mowers have lights. It is because in the South it is so hot that you mow either at 8 a.m. before it is too hot or wait until dusk.
The south is also the only place that I have ever been to where nobody goes to the pool by mid-July (except me) because the water is bath temp.
Back on topic.
Hydrate, exercise in the hottest part of the day for you, and do it a little bit longer so you can acclimate faster. Otherwise, like the release of EA assignments, it will be what it will be. You have no control over the weather.
