27. Smartphone Interference
For those that wear medical devices, be aware that smartphones can interfere with how they operate. Things like implanted defibrillators and pacemakers can be interrupted or stopped entirely by radio waves emitted by mobile devices. Even certain brands of hearing aids can be affected when you use a smartphone.
Smartphones can also cause issues at doctors offices and hospitals. If doctors and nurses have their phones on in their offices or operating rooms, that may pose a risk to their patients, especially those who wear medical devices. If any issues arise with your medical devices, contact your doctor for assistance.
