ELI5: Why does a slightly hot shower feel like you are burning when it touches your skin, while a hot tub set at 102F feels comfortable when you get into it?

In addition, a hot tub has its water somewhat static. When you enter, the hot water transfers its heat to you but stays roughly where it is, so it kind of forms a shield of slightly colder water around you. You notice, when you move inside the tub it gets hotter briefly.


In a shower, there's new hot water constantly touching your body, its gonna be hotter.
