Go for a walk in the mornings if a run is too daunting. Gradually go up.
A problem I had is I’m too dedicated to some things and will run a lot and then injure myself by going too often or beyond what my body is capable of instead of ramping up in a healthy way. Then I wind up doing nothing again due to injury.
I think it can depend on where you live and dry heat vs humid and stuff, but in general I agree.
I would sleep with a fan instead of turning on AC.
