Have you ever spent some time on your cell phone and then felt this "deep warmth" in your head? I've felt the same warmth after having gone through a "full body scanner". I've mentioned this to a coworker before and he laughed at me. Then I heard him be on the phone for like 30 minutes and during lunch he mentioned that his head was feeling this weird warmth. I repeated my theory and asked him what are the odds of his phone usage and the warmth being unrelated. I've never seen him not use headphones when being on the phone since then.

In the politest way possible, and without dismissing your feelings, it seems that you have discovered the placebo effect in action.

    The blog post is not credible. The author does not provide evidence for stating that heating tissue causes harm. The scientific paper describes heating of almost the exact magnitude as normal diurnal body temperature variation.

This is a nocebo effect. The two things you just described aren’t even in the same ballpark of RF frequency. The brain doesn’t have any way of measuring pain; let alone temperature. Brain surgery can be done with the patient awake in desirable situations as a direct result of this.

    The brain does not have pain receptors, but the head and the neck have lots.

this happens to me. Also I would get "phantom calls" right before my phone was about to ring. Sometimes I had leg twitches when I kept my phone in my pocket, that I thought was just a pinched nerve, but my phone would then begin to ring. I no longer store my phone in my pocket and have not had phantom calls/leg twitches. Placing my phone near a speaker I could correlate that the frequency of the twitches matched whatever frequency the phone pinged the tower. Not proof but very suspicious. Interesting enough I have been disabling my wifi at home at night because I was challenged to see if I felt a better deeper sleep. I did, but I have not ruled out placebo effect. I want to randomize this somehow and record which days I think it is off (depending on my sleep) vs days it is on, to rule this out. I am horrified that EMF could be affecting me like this if it is true. I live in an area without other wifi, 3g, or 4g. I do not own a frequency counter, but that would help me eliminate other interference for better test results.

  This type of uncontrolled self-experimentation is extremely fraught with bias and is not a reliable way to reach a conclusion at all. For example, you discount all the times you get a leg twitch and your phone doesn't ring. You probably don't even register it. Your muscles most definitely are not activated by 1-3GHz radio waves broadcast at less than one watt. Otherwise you'd be dancing like a marionette 24/7. And the sleep experiment is even worse. How do you quantify "better deeper sleep?" Please don't spread this kind of anecdotal pseudoscience, it just makes the rest of the world more uninformed. The more confidence you have in your objectivity and expertise on the subject, the worse your bias gets. People who work with tech have to be doubly sure to control for bias.

That would be due to the cell phone creating heat (because CPUs etc use energy), not due to microwaves...

  It’s heat that’s felt after you stop calling.
