It’s a hot day and there is no air conditioning, the solution is a no-brainer right? Grab an electric fan to cool yourself off! Well, new research from the non-profit medical group Cochrane Collaboration says there's actually no hard evidence that fans are either an effective or safe way to beat the heat.
Based on this evidence, the researchers concluded that electric fans could potentially do more harm than good at temperatures above 95 degrees. 95! We’ve already spent a dozen days this summer above 95, so that is a big concern. We’ve always known that fans don’t actually cool the air temperature, but they were thought to help regulate human body temperature by assisting with physiological mechanisms, such as sweating, which promotes heat loss.
