Then the problem is not the heat, but your fitness level, which regular biking, jogging will improve. It did for me. After about 20 years of no exercise, just sitting in front of a computer, I decided last November to start exercising (jogging. Bad knees make biking a bad idea)

My 1st day out jogging, I could only go 0.5 miles non-stop before I almost passed out. Today I can do 5.5 miles non-stop. My cardiovascular system is in the best shape it has been in a long time. And I'm almost 60.

I have quite a lot of exercise, but I have hard time tolerating high temperatures in general, and it has been getting worse with age. I should have been born somewhere in Siberia.

I simply just want to do other sports and want to have the choice of what I do for exercise, and have maximum freedom to how I spend my (free) time and energy, and not use most of it on commuting.
