With over 5 billion people using them worldwide, it is well known that cell phones operate using radio waves. However, not as many people are aware of the health risks associated with constant exposure to such radiation.

Radiofrequency radiation, a form of low frequency, non-ionizing electromagnetic radiation, is emitted from a cell phone’s antenna and be absorbed into whatever part of the body is closest to the device. These are the same types of waves utilized in microwave ovens to heat food.

While no major discoveries have been found in studies relating to its correlation with cancer, the same can not be said for animals. Rodents exposed to radiofrequency radiation were shown to have a greater risk for cancer, tissue damage, and lower body weight in comparison to those not exposed.

According to the National Center for Health Research, cell phone radiation can cause migraines, dizziness, less and poorer sleep, and electrohypersensitivity in humans. In order to prevent these effects, researchers recommend people change small things to decrease their radiation exposure. For example, people should avoid carrying their phones on their person, use hands-free devices, and limit cell phone use in areas away from cell phone towers due to the increased amount of radiation emitted.

The scientific community will be continuing research on this topic for years to come, as new discoveries are frequently being made.
