Heating and ionization are not the only ways in which chemical reactions can be influenced. See: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4340277/ for an overview (contains both positive and negative results).
Cool. All it takes is replication. The trial lawyers will beat a $100B path to your door once those pesky negative results are accounted for.
Oh, and in the meantime, I'd avoid hanging around near fireplaces and stay out of the sun, because "THz" is basically a synonym for "long-wave infrared."

Yes, but this says nothing about whether the spectrum is smooth versus a spike, which could make a difference. Anyway, I think it can be a mistake to hide behind known mechanisms, while the empirical evidence shows that something else is going on.
