TL;DR. The nervous system discharges activation by oscillating between activation and safety ('pendulation'), not by diving deeper into discomfort.

The pendulation principle

Somatic experiencing, developed by Peter Levine, frames the nervous system as discharging activation by oscillating between regions of charge and regions of ease. The mistake most people make — and most meditation apps encourage — is sinking attention into the area of pain or tension.

The somatic-experiencing move is the opposite: alternate attention between the uncomfortable sensation and a neutral or pleasant one. The nervous system processes the activation without overwhelm.

Relevant research: Payne, Levine & Crane-Godreau, 2015 (Frontiers in Psychology).

Why pendulation beats 'sit with it'

For people with trauma history or high anxiety, the 'sit with the sensation' instruction common to mindfulness traditions can trigger overwhelm — a process called flooding. Pendulation is a safer default because it guarantees the nervous system has a place to rest.

The published evidence on SE is smaller than on MBSR or ACT but converges on the same direction: oscillating between activation and safety is the reliable mechanism.
