Although there are still no confirmed studies about evidences that cell phones can cause cancer to humans, some science reports suggest that electromagnetic radiation coming from a cell phone antenna can trigger a brain glucose increase in the head area closest to where the cell phone is held. But if you want to avoid or minimize your exposure until all the evidences are officially confirmed, there are still proven safety tips that you can follow:
- If you are having calls, use the speaker phone setting or wired hands-free device instead of getting direct contact to your ears during the call. But wireless bluetooth devices don't mean to eliminate the exposure though.
- A cell phone's radiation exposure tend to be high when your phone's signal is weak or when you're traveling in a fast moving train or car. It's because the phone needs to reconnect to new towers. It should be safer to wait until you have at least 3 or more bars of signal strength before you make a call.
- Younger kids' skulls are thinner than adults, the reason why they are more highly at risk in radiation exposure when they hold their phones to their ears during a call. Encourage them to text.
