LANSING, Mich. — Turning on that fan might save you from the sweltering heat--but it might not be the best option for your body depending on where you live.
A group of scientists in Australia looked at how fans affected the human body in both dry and humid conditions.
Researchers say fans speed up how fast sweat evaporates from your skin, making it harder for your body to fight the heat.
If you are in humid areas though, you're in luck. Sweat doesn't evaporate as easily in humid air and can make using a fan more effective.
