Assuming you can't spend a heat wave bobbing up and down in some cool body of water, the next best option is to hunker down inside with air blowing on you, right?
Preferably it's from an air conditioner set on arctic chill.
But if there's no AC, then an electric fan would be the next best thing, wouldn't you think?
Well, it turns out health experts aren't so sure about electric fans. And they say using one in a really brutal heat wave can sometimes do more harm than good.
