The weights themselves are almost certainly out of my price range. I just don’t care enough about getting this done to work around my monetary neuroses. It turned out that my roommate has some 3lb weights (not covered with anything that would respond interestingly to refrigeration) and I was messing with those; my hands were not excessively warm during this process, so cooling something I hold in my hands would be of minimal help.
The thermoregulation experiment suggested that cooling the hands is a relatively efficient way to cool the whole body. I don’t think many people feel like their hands get too hot while they exercise, but there are apparently gains in endurance when exercisers keep something cold on their hands. These gains are most likely due to the body taking longer to overheat.
You could find out whether this works for you by timing how long something takes to produce noticeable overheating or sweat, then timing the same thing on a later day in very similar conditions, holding ice packs or something like that in your hands.
If you don’t want to induce extra overheating or sweat for the sake of the experiment, you could try holding something cold while doing something you have to do anyway (e.g. sometimes I have to go outside on a hot day). That way the worst likely outcome is not much worse than before unless you really hate holding cold things.
The weights only need to be made of something with reasonably high thermal mass, and the coating only needs to have thermal conductivity in a range that will allow the transfer of heat from your hands to the weights quickly enough to be useful but not quickly enough to be painful.
My theory here is that your core is well-insulated under most of your skin, but that the soles of your feet and palms of your hands are effectively gaps in this insulation. Under this theory, I would not expect your hands to feel hot when you’re exercising, since they contain no major heat source and have ready access to a major heat sink (the outside world). Cooling your hands just makes them a better heat sink for the rest of the body, reducing the need to sweat.

I suppose I’ll pop the weights in the fridge and see what happens; couldn’t hurt.
