Sunlight shining on one side of a cube-shaped liter of flesh would be 10W/kg or so on average (and about 100W/kg if we consider the top 1cm).

1.6W/kg is a conservative limit.

I'd sure hope the exposure is orders of magnitude less than sunlight, considering how clear the dangers of sunlight are.

Why? The danger of sunlight is ultraviolet. That's only about 4% of sunlight.

Oh and it's worth mentioning that everything around you at room temperature is emitting 400 watts per square meter of infrared. That's almost as much infrared as you get from the sun (1kW total, roughly 4% ultraviolet, 53% infrared, 43% visible).

You're absolutely right, different wavelengths of EMR have wildly different effects on humans, so the comparison falls short that way as well.

Most of them just heat, though. And in terms of heat, you don't need to be "orders of magnitude" below sunlight. It's not exactly hard to have two walls in the same room differ by 100 watts per square meter.

Radiowaves are non-ionizing radiation. Your DNA isn't going to be destroyed from anything below UV. Local heating from RF absorbtion might cause issues for certain biological functions but local heating can come from things like a warm laptop sitting above your crotch and reducing sperm count via heat. You need a lot of RF power to cause local heating though, think on the order of a microwave oven, not what a typical phone puts out.

Yeah, but it is important to consider the wavelength. Did our cells evolve to handle constant RF exposure?

It's not really relevant for non-ionizing radiation such as RF, as the primary impact on our cells from RF is just heat.

And the thing to know about evolution and life is that life evolved to be robust in the face of changes and different environments.

I'm not an expert but while less dramatic than ionizing radiation, it certainly has more effect than just heat. Think RF can induce potentials especially as it regards cells ion transport, gates. And yeah, my question is more oriented towards whether human life is adapted to RF, I'm sure some bacteria would

On the upper end of the RF spectrum, the thermal radiation given off by us and everything around is is ever present.
