On the side of sensible caution when presented with unknown factors, yes. That does not apply when there is neither practical evidence nor any room for justified suspicion. At that point it might at best be silly, even if not harmful. Depending on the subject at hand, acting out and advising caution on things that are well understood to be harmless can be very harmful.

Non-ionizing radiation is a very well-understood topic, and we also know very well what energies are required to do harm, and what harm it does.
