Abdominal warmth phrase ("My solar plexus is warm")

Direct the warmth phrase to the abdominal center to deepen parasympathetic activation.

Why it works

The solar plexus (celiac plexus) is a major autonomic nerve network in the abdomen. Directing warmth attention there may extend peripheral vasodilation inward, and there is a practical reason for the pairing: warm hands and warm feet accompanied by cool, easy abdominal attention mirrors the body state of parasympathetic rest. The abdominal warmth phrase is also connected to gut physiological responses — some practitioners report reduced gut tension with this phrase, consistent with the gut-brain axis and autonomic influence on digestion.

How to do it

1. After limb warmth, move attention to the abdomen, just above the navel.
2. Repeat: "My solar plexus is warm..." with the same passive, observational stance.
3. Imagine warmth spreading gently through the abdomen.
4. If gut tension or discomfort arises, do not force warmth; simply observe and allow.

Evidence

Abdominal warmth is the fifth standard AT exercise; it is included in the meta-analyzed protocol. Specific physiological evidence for abdominal vasodilation via AT is more limited than for limb warmth, and the practical benefit is partly based on clinical observation. The meta-analyzed protocol referenced here is Stetter and Kupper's 2002 synthesis of AT clinical outcome studies. (clinical)

People with gastrointestinal conditions, recent abdominal surgery, or gut-related anxiety may find this exercise triggers rather than relieves discomfort. Proceed carefully and skip if uncomfortable.

Common mistake

Skipping the abdominal phrase because it seems abstract or produces mild discomfort, rather than staying with it long enough to notice whether the discomfort passes as passive attention normalizes the sensation.
