Basically, they don't. THz waves are light at very low energies. Much too low in energy to break any chemical bonds -- they about a 1000 times lower energy than the ionization threshold for stripping electrons off atoms. Some very specific THz frequencies can resonate with vibrations of atoms within molecules, but to directly cause enough vibrations to actually heat and therefore damage a person's molecules would require a very high power, very focused, and very specific frequency emitter. Broad band THz emitters (such as the THz light from the heat of every object around us) will not harm people.
