Exposure To Radiations
There are several different types of radiation, and we classify them according to the amount of energy they carry. Ionising radiation carries a lot of energy, and excessive exposure can damage our cells and DNA, causing burns, sickness or cancer. Non-ionising radiation can cause a temperature increase – this is how microwaves work. The radiation emitted by smartphones falls into this category; however, it gives out less than two watts of power, causing only a tiny amount of warming with not enough energy to damage our cells.
The American Cancer Society (ACS) states that smartphones could represent some risk associated with cancer, but the evidence is not strong enough to be considered causal and needs to be investigated further. If you are concerned about radiofrequency exposure, you can limit your exposure by using non-Bluetooth headphones or using plane mode at night.
It’s important to bear in mind that smartphones are still relatively new in history, and more studies are underway to try to confirm suspicions. So far, scientists have reported adverse health effects of using them, including changes in brain activity, reaction times, and sleep patterns.
