They are a little inaccurate.
Yes there is a spa, several in fact, that offer python massages. No, they don't use any giant pythons, and the benefits have nothing to do with fear. I've seen numerous pictures and articles on Facebook related to these spas. I have seen ball pythons, RTB, and a few small Burmese used, usually a massage involves two snakes and two therapists, and the animals are well kept and fed on schedule, not just before a massage. Personally, I've said for a long time if I could train mine to massage on command I'd make a fortune with them. They are excellent therapy for my tension headaches and the pinched nerve in my neck.
Of course, given that we are talking about mainstream media here, expect them to take a nugget of truth and twist it into a mountain of fantasy to boost their ratings.
