We’ve officially reached the peak of summer, which means two things: one, we can begin our countdown to autumn (yes, already). Two, it is very, very hot outside almost everywhere. This summer has, so far, brought record high temperatures to most of the world, and that doesn’t seem to be stopping any time soon. Dealing with the heat during the day is one thing, but dealing with it at night? That’s when things get insufferable. It’s difficult, if not impossible, to fall asleep when you’re sweating profusely and sticking to your sheets. We can’t all afford air conditioners, and sometimes need to make due with a simple ceiling or floor fan to move the air around a bit. Unfortunately, this can have some less than pleasant side effects, leading many to wonder: does sleeping with the fan on make you sick?
