In this article, we explain why some people are worried about Bluetooth headphones, like iphone bluetooth headset. We also look at the evidence regarding the safety of these devices.

What is electromagnetic radiation?

According to the National Institute of Environmental Health SciencesTrusted Source, electromagnetic radiation (EMR) is an invisible area of energy. Both natural and synthetic objects can emit EMR.

When an object emits EMR, it sends out waves of electromagnetic energy at different frequencies. According to the Centers for Disease Control and Prevention (CDC)Trusted Source, the higher the frequency of the radiation, the higher its energy levels.

There are two main categories of EMR:

Ionizing EMR

These waves of EMR are of relatively high frequency and have the potential to damage human cells and DNA.

The term “ionizing” means that the EMR is able to remove electrons from atoms. This capability is why ionizing EMR is more harmful than nonionizing EMR.

Sources of ionizing EMR include:

sunlight

sunbeds

X-ray machines

radioactive waste

Nonionizing EMR

These waves of EMR are of relatively low frequency and do not generally cause adverse effects in humans.

Sources of nonionizing EMR include:

Bluetooth devices

cell phones

computers

WIFI networks

energy smart meters

microwaves

power lines

MRI machines
