Unlike ACs, fans circulate the air within your gym, which is beneficial for sustaining good air quality. Furthermore, fans consume considerably less energy than air conditioners, thus offering an eco-friendly advantage. Fanned air may help athletes who are in hot conditions feel more comfortable and save them from losing productivity.A fan doesn't decrease the room's temperature. Fans can actually increase the temperature by approx. 37.4 to 39.2 Fahrenheit. Fans provide a cooling sensation by accelerating the evaporation of sweat, which can be essential during a workout. In contrast, an air conditioner can cool the entire room. Such frigid environments can cause muscle stiffness, which is undesirable in a gym setting.
