How are radiations created?

“Phones emit radiation and cause cancer”. This is a sentence you must have surely heard in your life. This is because it is partially true. Devices that use wireless connectivity like Bluetooth, cellular connectivity, etc. emit radiations in order to transmit the data.

Since the smartwatches are wireless, this means they definitely emit radiations which are electromagnetic radiations. This is because wireless connections like Wi-Fi require electromagnetic radiation to send data. These radiations result in the creation of electromagnetic fields also known as EMF. The level of radiation emitted by the smartwatches must meet the FCC standards in order to be used by us safely. Another reason for the emission of the radiations is that the processors of the smartwatches operate at higher frequencies ranging up to a few GHz. This creates EMF within the smartwatches which makes them a constant source of radiation even when they are not being used.

Are the radiations harmful to the Human Body?

When buying or using the smartwatch, one gets worried about the harmful effects of placing this electronic device on your wrist for long periods of time. It is often asked, “is smartwatch radiation harmful?” Well, you don’t have to worry about it because these radiations aren’t harmful to the human body.

The effect of the radiation on the human body causing cancer depends on the wavelength of the radiation. If the wavelength of the radiation is low, meaning it has a high frequency, it will be harmful to the tissues of the human body. However, if the radiation’s wavelength is longer which means that the frequency is low, it can’t cause harmful effects on the human body. This is because they don’t have enough energy to penetrate into the tissues of the human body.

If a person is close to the radiation, it means he is exposed to them more and there are more chances of the radiation, affecting the human tissues. Smartwatches are wearable devices and are placed on the wrist, which means they are closest to the human body and thus the chances of affecting the human body by radiation are at their maximum.

However, the radiations produced by the smartwatches aren’t strong enough to affect the human body.
