<human>: I'm a little concerned about the health risks of using a cell phone. Do you have any tips for reducing my exposure?
<bot>: 
1. Try to keep your phone away from your body when possible, and use it in airplane mode or on speakerphone as much as possible.
2. Avoid using Bluetooth headsets, which can increase radiation exposure by up to 50%.
3. Use an external battery charger rather than relying solely on your phone's internal battery.
4. Consider investing in a protective case that shields your phone from electromagnetic fields.
