I am obese, so, like sea mammals, my blubber (yeesh) keeps me very warm, and I overheat very easily. I also just “run hot” as my mother said - when I was a skinny little child I would heat up the bed so my mom would make me go to my own.
I actually enjoy the exertion and payoff that comes from exercise. The thing I HATE HATE HATE HATE HATE is being hot. HATE!!!
I am addicted to these things, but how effective they will be for you depends on how you use them and how hot you get. The only way I can stand exercising is if I’m cool, so I have a bunch and what I do is freeze them. They get hard and a little hard to manipulate, but it doesn’t last very long. I put one around my neck, one around my head, one under my breasts in my bra, and one down my pants.
I know, sounds nuts. But if it makes it easier for me to work out where otherwise I wouldn’t, I think it’s the smart move.
Now, because I get VERY hot when I exercise, at the end of the hour they are not only defrosted, they are actually warm. Once they are warm they don’t help at all, as you might imagine.
One medium days for walking when it’s not that warm outside but I know the exertion will make me warm, I just soak one in cold water for my neck, maybe one for my head. If I keep turning them, that’s enough.
The cautions are these: make sure you don’t oversoak, they will start to split if the beads get too full. Make sure you let them dry out properly, or they will mildew (I will let them dry out completely and then dip them in chlorinated water when I re-hydrate them.)
After you’ve had them awhile, the material inside starts to seep through somewhat, making them feel slightly gooey when soaked, but it’s not that bad and it’s better than sweat.
