You are using the water as a medical treatment. That’s different from the question in the article.
I don’t normally take a morning bath on weekends when I don’t get up at 4:30am or if I’m on vacation. If I have time to stretch and start my day moving slowly until I can move I don’t feel the need for a hot soak to get me going. I know all that soaking isn’t good for the skin but as far as water goes we have a well that is in an underground lake and we have plenty of excellent water so I don’t feel guilty about wasting water.
I don’t like to take meds and if a morning hot soak helps then I figure that’s better than popping a lot of pills. Once I’m moving I’m good the rest of the day as long as I don’t sit too long.
I’m looking forward to retirement and when I do I’ll be down to a more normal once a day bath.
