My buildings water doesn’t heat up till like 9am or so. I forgot about that so I went to take a shower just now around 8am cause I wanted to get it done early. I ended up just taking a cold shower. I read there’s benefits to cold exposure especially first thing in the morning. It was uncomfortable at first but I got used to it after a few minutes. I prefer hot showers still but I might start doing those cold ones a couple times a week since cold exposure is supposed to be good for you and endorphins etc
