It is not widely discussed outside of the SHL, but players and staff know that the SHL has developed real world healing technology similar to Bacta tanks in Star Wars. At intermission, as well as before and after games, inured or ailing players are submerged in "hockey bacta", which almost immediately heals any wounds, as well as kicking the immune system into overdrive to kill viruses and bacteria that may harm the players and cause illness. It also builds up players' bodies to prevent further injuries that would otherwise be sustained during the game. Pairing this advanced technology with advancements in the effectiveness in protective gear in hockey has allowed the SHL to completely remove injury from hockey. Publically, of course, the SHL simply thanks the equipment advancements. This allows them to secretly sell the bacta tank technology to other sports leagues around the world at premium prices. Many of these leagues enter into "affiliate league" contracts with the SHL in order to obtain the tech. The contracts secretly contain NDA clauses that prevent the leagues from disclosing or selling the technology themselves.
