I wondered about this as well. And how do gas fireplaces (with 'logs' that light up red-hot) compare? Does it matter if you're facing it, or facing away?

If you feel radiated heat and see a bit of red infrared on a wide spectrum.

The infrared deeply penetrate the tissues, so it shouldn’t matter much.

Trust how you feel too.

It is best to do both, and your sides too.

The infrared does not go all the way through your trunk or legs or head.
