Are Neck Fans Effective During Heatwaves?

Wearable neck fans have become increasingly popular as portable cooling devices during hot weather, especially during heatwaves. They offer hands-free airflow around the neck and face, making outdoor activities and commuting more comfortable.

However, while neck fans can improve comfort and help reduce the sensation of heat, they are not a substitute for evidence-based heat protection measures such as staying hydrated, seeking air-conditioned environments, and limiting strenuous outdoor activity.

Their effectiveness also depends on temperature, humidity, and individual health conditions. Understanding both the benefits and limitations of neck fans can help people use them safely during extreme heat.
