The World Health Organization (WHO) has classified radiofrequency electromagnetic fields as "possibly carcinogenic to humans." This classification is based on limited evidence from studies that have found a possible association between exposure to radio waves and cancer. However, the WHO has also stated that more research is needed to confirm whether or not radio waves are actually carcinogenic.
The U.S. Food and Drug Administration (FDA) has stated that there is no conclusive evidence that wireless devices cause any health problems. However, the FDA recommends that people limit their exposure to radio waves by using hands-free devices and keeping devices away from their bodies.
The Federal Communications Commission (FCC) sets limits on the amount of radio waves that wireless devices can emit. These limits are designed to protect people from exposure to harmful levels of radio waves.
Ultimately, the decision of whether or not to use wireless devices is a personal one. There is no clear evidence that wireless devices are dangerous, but there is also no guarantee that they are completely safe. If you are concerned about your health, you may want to limit your exposure to radio waves by using hands-free devices and keeping devices away from your body.
