Health[edit]
There is little evidence supporting the claim that excessive cellphone use can cause or worsen health problems, but it is undeniable that it does affect users in many ways, physical and mental. Germs are everywhere, and with the number of times people interact with their cellphone under different circumstances and places, germs are very likely to transfer from one place to another. Research from the London School of Hygiene & Tropical Medicine at Queen Mary in 2011 indicated that one in six cell phones is contaminated with fecal matter. Under further inspection, some of the phones with the fecal matter were also harbouring lethal bacteria such as E. coli, which can result in fever, vomiting, and diarrhea.[6] Cancer, specifically brain cancer, and its correlation with phone use, is an on-going investigation. There are many variables that affect the likelihood of hosting cancerous cells that includes how long people use their phones and how frequently they do so. There has been no clear evidence indicating the link between cancer and phone use if used moderately, but research from the World Health Organization said that heavy usage will more likely increase the risk of developing glioma tumours – a common benign tumour, a rare but deadly form of cancer. Although a relationship has not been legitimately established, research is continuing based on leads from changing patterns of mobile phone use over time and habits of phone users.[7]
