I would say the warm shower causes less prediction error than the cold shower because it’s less shocking to the body, but there’s still a very subtle amount of discomfort which is hidden under all the positive feelings. The level of discomfort I’m talking about is very slight, but you would notice it if there was nothing else occupying your attention. I don’t mean to say it causes negative emotions. It’s more like the discomfort of imagining an unsatisfying shape, or watching a video at slightly lower resolution. If you compare any activity to deep sleep or unconsciousness, you can find sensations that grab your attention by being slightly irritating. As long as it’s noticeable I think it causes slight negative valence. But this is often outweighed by other aspects of the activity that increase valence.
Sitting at home doing nothing might involve the negative sensations of boredom, restlessness, and impatience, all of which disappear when we go for a walk, so any discomfort is hard to notice underneath the obvious increase in valence.
