After having an hour-long conversation on my cell phone yesterday, and having the whole right side of my head feel hot for a while afterward, I thought I would look into the negative (and some have argued positive) health affects cell phones can have. Furthermore, preventing any radiation damage is of interest due to the ubiquity of cell phones. If a cell phone has to send a strong enough signal to get from your mouth to the nearest tower, then doesn’t it also send a strong enough signal to penetrate reasonably deep into your dermis - and cause effects similar to the heating/destruction of food via a microwave oven (not to mention cell phones operate on a similar, albeit lower, frequency to microwave ovens, and wifi a and g actually operate at the same 2.4ghz frequency). My cell phone is always on, and spends most of its time at the same place in my pocket constantly (basically) sending out a signal a centimeter from my skin and inches from my precious jewels all day. What do you guys make of our situation in the modern atmosphere of electromagnetic radiation.
This has been studied quite a lot, and no threat has been found.
IIRC, cell phone radiation is not ionizing, and does not interact with the human body in any significant way.
The same thing happens to me after I talk to anyone for an hour.
That’s happened to me with regular phones, too. I think it’s just a function of pressing something at least somewhat warm to your ear for an extended period of time. Occasionally when I have my hand supporting the side of my head for a while, that side gets warm.
I bet the phone itself was hot too, most electronic devices get warm when active. Your head was warm because it was against a warm phone, nothing to do with dangerous radiation.
