Overview
- Continue Research links lifelong gravitational effects to reduced cerebral blood flow and proposes inversions, citing up to 17% lower flow when upright and a roughly 0.7% annual decline.
- The group reports passive inversions raise brain flow by about 20% and says a six‑week daily inversion routine increased average flow 7% in humans.
- Clinicians call the claim unscientific and warn that cerebral autoregulation, spaceflight data and known risks mean inversions could be harmful for older adults or those with hypertension, glaucoma or cardiovascular disease.
- Deepinder Goyal thanks skeptics, publishes a companion note addressing objections and says multiple teams, including a dedicated “contra” group, are running controlled studies to validate or refute the idea.
- Critics question marketing and transparency, urge release of raw data and peer review, and some speculate a consumer device is planned, which remains unconfirmed.
