Why don't we get heat stroke when we take a long hot shower or bath?

You can get heat stroke. There's a reason that most hot tubs and saunas recommend not being in them for more than 15 or so minutes at a time.

That said, you'll expel some heat via your breath just as other mammals do via panting. In a shower your body will continue to sweat. Some of that water will still evaporate, as will the hot water hitting you from the shower itself. Generally in a shower only one side of your body is being hit with water, so you'll radiate heat from the other side.

But, if you stay in a hot, humid shower or a hot tub long enough you'll eventually begin to experience symptoms of heat stroke. Shortness of breath, lightheadedness, tunnel vision, etc. Exertion will make it worse.
