How are you all exercising in the heat?

I don’t typically work out or go to a gym to exercise - I just live in a city and walk or bike everywhere and have no problem hitting 8-10000 steps a day. I usually put on a podcast at the end of my workday (WFH) and walk around for a while. But right now it’s almost a hundred degrees, humid, and I’m already overheating in my A/C-less apartment. I feel restless and would love to move around, but I know I’ll end up nauseous and woozy. Is it ok to be so sedentary every once in a while?
