Smartphones, being a very new invention of humanity, became an inherent part of human’s life. The smartphone combines different sophisticated features. It allows users to keep pictures, memories, personal info, correspondence, health and financial data in one place. Smartphones also became an integral part of modern telecommunications facilities. In most regions of the world, they are the most reliable or only of available phones. The phones allow people to maintain continuous communication without interruption of their movements and distances. Smartphones and handheld devices (HHD) combine advanced computing capability, such as internet communication, information retrieval, video, e-commerce and other features, that makes the device is one of the necessities for many people. The smartphone is a source of the eminence of electromagnetic waves. Numerous studies have been conducted in the past years to identify the effect of electromagnetic waves emitted from the cell phones on human health. The topic has been studied for a long time, but in past, it touched on a rather narrow circle of people, mostly staff of broadcast and specialized radio stations. Even at that time, measures taken to protect people from radiation apply only on those who work near powerful sources of radiation. And, despite the revolutionary changes in the field of telecommunications, as well as many discoveries and emissions, the impact of electromagnetic waves of different frequencies hotly debated ever since. As soon as mobile phones more and more part of our lives, the world is continuing research to proof whether cell phones are harmful to human health? Today there is no official statement announced by laboratory or medical center to answer this question. The complexity of the analysis of the statistical data makes the task more difficult for researchers. The impact of harmful radiation emitted from cell phones waves is still being studied.Advances in technology have allowed researchers to measure physical and chemical changes in an addict’s brain. Regardless of the addiction, even if it is just a smartphone, the regions that “control attention, executive control, and emotion processing” are impacted. These studies have discovered physical changes also occur in the dopamine system.
Dopamine is a chemical created by our bodies that allow us to feel pleasure and reward. Scientists noticed smaller amounts of dopamine receptors in brains of people who exhibited smartphone and Internet addiction.
This explains how some teens need an increase in certain activities, like receiving new notifications on his or her cell phone, to feel satisfied or happy. Likewise, this can also work in reverse and result in depression when they don’t get notifications or lose access to their smartphone.
