Can talking on a mobile phone be hazardous to your health?They even suggest keeping electronic devices such as desk-top and tablet computers out of the bedroom, or at least six feet from the head while we're sleeping.A growing number of health professionals worldwide are recommending that mobile phone users err on the side of caution until more definitive studies can be conducted.In May 2016, the UK's Independent newspaper reported on research by the US government's National Toxicology Program that showed a slight increase in brain tumors among rats exposed to the type of radio frequencies commonly emitted by mobile phones.Some researchers believe that other types of wireless technology may also be dangerous to human health, including cordless phones, wireless gaming consoles, and laptop or tablet computers with wireless connections.While both rely on electromagnetic radiation (EMR), the radio waves in mobile phones are lower in frequency.Some research suggests that heavy users of mobile phones are at a greater risk of developing cancerous brain tumors.They suggest replacing all cordless and wireless devices with wired ones where possible.They also say that many cordless phones can emit dangerous levels of Electromagnetic Radiation even when they are not in use.As a result, many experts now recommend texting or using headsets or speaker phones instead of holding a mobile phone to the ear.Mobile phone antennas are similar to microwave ovens.As a result, it is impossible to study long-term exposure to mobile phones.
