Magnets, metal loops, plate steel and thick wallet stacks can detune antennas and make phones transmit harder.

"If you're listening to a podcast for instance, do you turn off all RF

"It took me years to figure out my weird "headaches" that weren't
quite headaches, and now, 15 years later, I wonder if it isn't all the
tattoo work I had done in my youth that increased my sensitivity.
With all I knew about health and wellness, I never considered the
toxicity/metals in the ink."
Most Tattoo's contain metal ions. They don't interact well with RF. Also, reduces the quantum yield of the solar power.
