The waves emanating from Wi-Fi routers and mobile networks are called EMF i.e. Electromagnetic Field. These come under the category of non-ionizing radiation, meaning they do not have enough energy to damage the DNA of the body. Scientists say that the Wi-Fi signal used in common homes is within the prescribed security standards. Although research is still going on regarding prolonged exposure to it, at present no concrete evidence has been found that it causes serious diseases.
Some studies have indicated that waves emanating from electronic devices and networks can slightly affect sleep. In particular, it is said to have a mild effect on the hormone melatonin, which is essential for sleep. But experts believe that more harm than Wi-Fi signal is caused by screen time and the habit of using the phone till late night. Constant notifications and online activity keep the mind active which disrupts sleep.
