Disadvantages of mobile phone
In this era, the prosperity of advance technology is blossoming like mushrooms growing in the back yard. Meanwhile, invented in 1973 by Martin Cooper, mobile phones nowadays are becoming one of the most popular pieces of technology and nearly everyone own a cell phone. Nonetheless, mobile phones bring not only easiness in communication area, but also many negative effects. Therefore, I am convinced that negative health effects, the effect on children and the infertility in men are the main disadvantages of using mobile phone.
First, negative health effects of using mobile phone have been proved by many studies. From the studies, mobile phone can emit microwave radiation that is detrimental to health. In fact, many reports on the health risks of cell phones have been published over the last few decades. A study led by Dr Agarwal, gives the consequences of the microwave radiation when you use cell phone. First, electromagnetic waves alter electric activity of the brain and cause disturbance in sleep; cause difficulty in concentration, fatigue, and headache; and increase reaction time in a time-dependent manner. Another is that they increase the resting blood pressure and reduce the production of melatonin. Moreover, they are also implicated in DNA strand breaks. In addition, the use of cell phones has also been related to Alzheimer’s disease and Cancer. In 2002, Hardell et al published a study titled ‘Cellular and cordless telephones and the risk for brain tumours’ in the European Journal of Cancer Prevention. Hardell et al found that people who used cell phones were two and a half times more likely to have a temporal brain tumor on the side of the head where they held their phone. In the case of tumors of the auditory nerve, which connects the ear to the brain, the risk increased to more than three times for cell phone users. In short, mobile phone is able to harm users’ health according to these
