Regarding the news circulating on social media about using earphones while charging a mobile phone, whether it affects the brain or nervous system, and how dangerous an electric shock could be,
Currently, there is no research that confirms 100% whether the waves from mobile phones are harmful or not. Research findings are mixed, with some agreeing and others disagreeing that electromagnetic waves from mobile phones can cause cancer or brain tumors. Therefore, the recommendation is to follow safety principles such as:
- Avoid talking on the mobile phone for long periods
- Avoid using the mobile phone when wet
- Keep the mobile phone away from the body while sleeping
- Do not use the phone while charging because if a short circuit occurs, the electric current can flow through the body directly to the brain
Normally, if there is a short circuit problem with electronic devices as reported in the news, using non-standard devices increases the risk of short circuits, which can cause the devices to explode or leak electricity. If it is a mobile phone with earphones plugged in, it is possible that the earphone wire will conduct and transmit the leaked electric current into the ear. Since the ear is directly connected to the brain, this can increase the severity of the injury.
If the leaked electricity is not significant, it can still damage the nervous system, such as causing dizziness. However, if the amount increases, it may cause an electric shock, which is when electricity flows through the body. Some patients may lose consciousness, usually for 2-3 hours, but commonly for 5-10 minutes, depending on the amount of electric current. After regaining consciousness, patients may experience memory loss or temporary confusion. In more severe cases, there may be behavioral changes, abnormal mental states, brain damage, weakness, seizures, and headaches.
