Electric fans may not help beat the heat

A new study in the Chochrane Libray finds fans might help you cool down if the temperature is below 95 degrees and if the fan is not directly aimed at you.

If the temperature is above 95 degrees the fan might actually increase heat gain and sweating. That could lead to dehydration and the problems that come with it.

Authors say there are simply not enough credible studies around to show the benefits and harms of electric fans.
