In order to grow, you should push at the edges of your comfort zone; nether staying entirely within the known, nor leaping put into the unknown and flailing wildly not knowing what is gong on.
"cold showers" is a counter-example of this, it is "performative discomfort" as you say without a learning. Not all discomfort is productive in itself. Discomfort is a side effect that has other causes.
But discomfort is an effect of this learning, even a marker: in the words of David Bowie, "If you feel safe in the area that you're working in, you're not working in the right area. Go a little bit out of your depth. And when you don't feel that your feet are quite touching the bottom, you're just about in the right place to do something exciting."
