We have a heatwave coming through the Midwest right now, high is 101 but with humidity it feels closer to 112! Just running out over lunch to feel up my car with gas I was sweating, any tips on staying cool?

And how to get some exercise in such extreme heat? I"m not allowed to do much more than walk and swim due to my cyst, and I don't have a pool at my disposal. We were going for nightly walks, but it doesn't get below 80 until after 1 am, not waiting that late!
