15-Second Diaphragmatic Breathing for Panic
Dr. Amen emphasizes that the first rule for anxiety is not to flee the triggering situation, because escape teaches the brain that the situation is dangerous and reinforces the anxiety loop. He then teaches the 15-second breath as an immediate, portable tool. Many people hold their belly in (vanity), but that restricts breathing; sticking it out is crucial. He also advises writing down the anxious thoughts to examine them, and notes the 18-40-60 rule: at 18 you worry what others think, at 40 you don't care, at 60 you realize nobody was thinking about you anyway. If needed, he layers on hypnosis or supplements like theanine, GABA, magnesium, ashwagandha, and curcumins. However, he strongly cautions against benzodiazepines due to association with addiction and dementia.
When you breathe in and push the belly out, the diaphragm flattens and increases lung capacity, slowing the heart rate and activating the vagus nerve. The extended exhale shifts the autonomic nervous system from sympathetic fight-or-flight to parasympathetic rest-and-digest, reducing the stress response.
Diaphragmatic breathing is as effective as Xanax. And there has no side effects... 4 seconds in, hold it for a second and a half, 8 seconds out... It'll break a panic attack in under four or five breaths.
