Kevin, it’s not about the energy.

It’s about the way a signal changes over time (modulation)

The way the field is oriented in space (polarization)

The way power is concentrated in short bursts (PAPR)

The way energy is spread across frequencies (bandwidth)

The way noise raises the floor, lowering SNR (signal-to-noise ratio)

The way beams are shaped in space (beamforming / spatial structure)

The way signals mix inside nonlinear tissues, creating new intermodulation frequencies

The WAVEFORM structure.

What kind of modulation is good, and what kind is bad? (When the radio DJ plays Vivaldi, is it worse for you than when he plays Wagner?) What polarization is good, and what is bad? What frequencies are good or bad for you? What signal-to-noise ratio is good and which is bad? Saying that these things cause health problems in themselves is rash and very unlikely to be true. After all, lightning contains every frequency from DC to daylight, and, unless it hits very, very close to you (enough to cause heating), it has zero effect on human health. And the fields that lightning produces, even at a mile away, are vastly greater than anything riding in on your power line.
