I feel like there's value in the "shock?"

As in, don't do it gradually.

Drop it INSTANTLY and just see how long you can last, even if it's only a few seconds. I know at first I was like okay, 5 seconds f* this.

But then you can make it a bit of a game for yourself, and after a while it just becomes habit.

(and fyi, I live in Florida, so staying in longer is much easier-- But I can say this switch made me change from dreading visiting relatives up North because that would ALWAYS make me sick --- to "aww yeah super cold showers in the morning," and you know, not getting sick.)
