I’ve heard my whole life that “you burn more energy waving a fan than by just not moving” and I was wondering if there was any truth to this. I’m currently using a foldable paper fan and it seems to be pretty effective. I don’t have an air conditioner so this is a dire situation

Well clearly you burn more energy waving anything around then by not doing so. But the point of a hand fan isn’t to decrease energy use but to increase relative comfort. A nice slight breeze is usually enough to make us *feel* slightly cooler even though we’re using energy to do it. Exercise bikes back in the day operated on this principle, by having the thing you move also be a fan that sends air at you. So, by pedaling you also create a breeze to help you keep cooler.
