Stellate Ganglion Block Increased Williamson's HRV by 30 Percent Overnight
"I did one side one day, one side on the other with Matt Cook at BioReset, who's kind of the number one in America for this. It was a 30% increase in HRV. The 30% increase in HRV overnight. And that held for, I mean, I'm what, 3, 4 months now after it started to tickle back down."
About this episode
In this episode of Modern Wisdom, host Chris Williamson is joined by author and investor Tim Ferriss along with entrepreneur Nirav Tolia and recurring guest George Mack for a wide-ranging three-hour conversation covering neuromodulation, AI's societal impact, the meaning crisis, and cultural differences between the US and UK. The most newsworthy revelation came from Ferriss, who disclosed dramatic anxiety relief using transcranial magnetic stimulation (TMS) combined with neuroplasticity agents, reducing his generalized anxiety from 8-9 out of 10 to near-zero for months at a time. He revealed investing in AMPA Health, a neuromodulation startup, and said brain stimulation has replaced psychedelics as his primary mental health intervention over the past three years. Ferriss also disclosed an embarrassing and previously unreported side effect from his first successful TMS treatment: a two-week inability to ejaculate that his doctor had never witnessed before. Williamson contributed data showing the UK arrested over 12,000 people for social media posts in 2023—nearly double second-place Belarus and far exceeding Russia and China—sparking debate about Western civil liberties. Tolia revealed that many San Francisco AI researchers privately believe fundamental problems are solved and AGI will arrive rapidly. The conversation expanded into the future of user interfaces, the iPhone's dominance, looksmaxing via AI, and whether secular society can generate meaning without religion. Williamson also detailed his own stellate ganglion block procedure, which increased his HRV by 30% overnight. The episode blended personal experimentation, insider tech commentary, and philosophical inquiry into what happens when technology removes scarcity.
Key takeaways
- Tim Ferriss reported transcranial magnetic stimulation reduced his anxiety from 8-9 to 0-1 for months, replacing psychedelics as his primary mental health tool over the past 3 years.
- Ferriss disclosed his first successful TMS treatment caused a two-week inability to ejaculate, a side effect his doctor had never seen before.
- Chris Williamson cited Freedom House data showing the UK arrested 12,183 people for social media posts in 2023, nearly double Belarus and vastly exceeding Russia and China.
- Nirav Tolia claimed many San Francisco AI researchers privately believe most fundamental problems are solved and AGI will arrive rapidly with self-correcting systems.
- Williamson underwent stellate ganglion block injections that increased his heart rate variability by 30% overnight, with effects persisting for months.
- The group debated whether secular society can generate meaning without religion, citing Viktor Frankl and the hero's journey as frameworks for post-scarcity purpose.
- Tolia is building SKYE, an AI-native iPhone home screen designed to reduce doom-scrolling by surfacing relevant information proactively rather than through app tapping.
