PolyvagalGuide is a practical, science-honest resource for understanding your nervous system and doing the daily work of feeling safe. Healings, not therapy.
Who writes this
Hamza K. Siddiqui holds a Bachelor’s degree in Applied Psychology and writes PolyvagalGuide’s guides to the nervous system, with a focus on healing and holistic living. The aim is simple: take the research on regulation, safety, and the vagus nerve and turn it into plain, usable steps. Hamza is not a licensed clinician, and every health article here is grounded in cited primary research and, where noted, reviewed for accuracy.
How we handle a contested topic
Polyvagal theory is influential but scientifically debated. We say so plainly, present both the ideas and the criticism, and keep our claims to education and self-regulation rather than treatment. See Is Polyvagal Theory Legit? for how we handle the science.
