Techniques

# What to actually do, and how well it is tested

These are the Regulate step: things you do with your body when a feeling has already arrived. Each page gives you the method in full, and says plainly how strong the evidence behind it is. Some of it was measured in a trial. Some of it is reasoning from how the nervous system works. You should know which is which.

Mechanism, not trials

## Breathing

Strong physiology

## Cold water

Mixed evidence

## Magnesium, calcium, vitamin D

Calcium has the strongest trial. Vitamin D was tested only in deficiency. Magnesium has no tested dose at all.

## A technique is not the whole thing

Settling your body is one step of three. Reflect on what the feeling is actually about, regulate so your body is not making the decision, then respond. The guide walks through all three, and the research section shows every finding these pages are built on.
