Ah Wim Hof, reminds me of my friend that had to fight crippling depression.(and still is fighting) He found out about the cold shower, breathing technique from Win Hof, and started practicing it.

What worked better than cold shower was Ice bath in the frozen lake. I were very skeptical at the practice first but oh boy, the sudden freezing shock really do wake some survival instinct inside you out, and your mind becomes really sharp. Until you keep doing it to a point of dizziness reminiscent of certain highs. If you are going to try cold shower, ice lake bath with sauna is also a experience worth trying out!

It didn't help him get out of depression, but sure did energize him more for a brief period of time in his life. (until his routine collapsed)

I did cold showers upto 10minutes, cryotherapy -90celsius upto 6min, hydrogen cryotherapy (-130c) upto 4 min. And only the supercold hydrogen gave me a (very) noticable and pleasant endorphine boost. Haven't tried ice baths yet.

I remember participating in a study for a friend of mine where I had to go into a cryochamber and I remember 2 very distinct things

1. How warm -60c felt after walking around in -130c for a few minutes in just shorts and shoes.

2. How much I wanted to run once I got out of the chamber. I was not a runner and I never liked running but I really wanted to run.

I kind of want to do it again to feel that high. Cold showers got a smaller reaction but something similar.

I need to get back into cold showers again but I definitely felt best when I was doing cold showers, it's a cheap trade of a few minutes of unpleasantness for such a mood boost but it's hard convincing yourself to do it first thing in the morning though.

Kambo, a properly dosed frog poison applied to the limbic system by first searing small dots through top layer of skin, has a similar effect by strongly engaging the immune system once it detects the poison - and causes a whole body reaction where the limbic/lymphatic system rapidly clears out the poison (and whatever other stagnant toxins are in the system), dumping them into the stomach which then have to be thrown up to clear them.

There are trained/certified shamans who offer kambo ceremonies.

Could you cite a source that says that toxins are dumped into the stomach in particular? I’m not very educated in anatomy but I’ve never heard of the lymphatic system interacting with the digestive system in this way. Thank you!

I'm also curious, but sceptical because "toxins" is often used as a generic vague term when advocating pseudoscientific remedies.

Wikipedia states that no pharmokinetic studies have been done on this "Kambo cleanse". https://en.m.wikipedia.org/wiki/Kambo_cleanse

Ice lake bath + sauna is almost better than any drug.
