I have found wim hof's 2016 book. it has a cold protocol that extends past 2 minutes of shower (does longer showers). i can try switching to that book.
i have a thermometer in the mail to handle the temperature at a more slow pace. my plan is to restart from a short number of seconds, and keep posting here even if i feel like a jerk doing so. this is the book i have now: https://libgen.li/edition.php?id=137402024 the shower protocol is faster in this one. i might slow it down or something, we'll see.
