A number of studies have shown that exposure to the radio frequency waves emitted from mobile phones & laptops can cause various health problems.

There's no denying that there's a lot of benefit and convenience we get from our devices.

However, simple precautions you can take to reduce the levels of radiation you absorb from using your devices may include:

- Keeping your mobile phone as far away from your ear and body as possible at all times.

- Avoiding Bluetooth headsets - these pose serious radiation hazards because they act as mini wireless antennas and blast EMFs directly into your ear and head.

- Keeping laptops off your lap and away from your body as much as possible.

- Not sleeping with your devices next to your head.

P.S : Using your device while charging is more harmful than when it's not plugged in.
