Thanks for the detailed explanation of the benefits of cold showers.

I took cold showers when I was conscripted in the military for two years - no choice.

Maybe 2-3 years ago, I took cold showers on and off because I wanted to save on my utilities bill. Yup, that practice never took root. Haha.

I’m keen to try this again. Especially when your post reminds me of how the Finns go swimming in the river during winter to build their sisu (resilience). Very similar to what you write here!
