I have considered this modality for some time, however having spent many years coming to understand what it takes to rebuild the adrenal glands, when I hear someone tell me that 'they feel good' ... 'as long as they jog X miles every day', or 'as long as they sit in an ice bath every day', it raises red flags.

If one requires going to such extreme measures, in order to feel good, that is a reliable indicator of adrenal insufficiency.

Our ancestors were able to have very robust mental & physical health, without the need to go jogging every day, or sit in ice baths, etc.

There are many forms of cold water therapy, a number of which don't involve shocking or overstimulating the adrenals (which at this time, tend to be weak, in most people).

For now, these are the forms of cold water therapy that I will practise / reccommend to others.
