The shower is higher humidity though, and the hot water makes direct contact, so the heat is more conductive. Similar for a steam sauna, they are more potent at the same temperature. Also infrared saunas, but for a different reason (the light is absorbed directly into the tissue, without needing to heat the air). So it's definitely not just about temperature.
