SONA ear device stimulates vagus nerve to cut stress; doctors call for more trials
Summary
- SONA is an AI-powered ear device developed by founder Jane Ollis that aims to reduce stress and improve sleep through personalized vagus nerve stimulation.
- The device reads heart rate variability and breathing, stimulates a vagus nerve branch in the ear, and adjusts stimulation in 10-to-20-minute daily sessions.
- In 2024, 30.5 percent of U.S. adults had short sleep duration, which the CDC links to conditions including obesity and depression.
- Ollis says early proof-of-concept studies show strong signals, but doctors say the device is unproven for sleep and want sham-controlled trials.
Reactions
- Dr. Mintimer Missarov said SONA is probably safe with a plausible mechanism but unproven for sleep, and called for a larger randomized trial with an identical sham device.
- Dr. Craig Zebuda said the science behind the idea is good but trials must show users actually sleep and feel better, not just better numbers.
- Chelsie Rohrscheib said the adaptive approach is potentially more sophisticated but called for robust research in a large, diverse population.
- Dr. Hanul Bhandari said personalization is not evidence of efficacy and greater effectiveness remains to be demonstrated.
- Jane Ollis forecast that her team's next sham-controlled studies will prove that personalizing the dose makes the difference.

Scientists develop device to reduce stress—but doctors warn there’s a catchA Newsweek article by Soo Kim covers the SONA, an AI-powered ear device its founder Jane Ollis says reduces stress and improves sleep by reading heart rate variability and breathing, then stimulating the vagus nerve accordingly, in 10-to-20-minute daily sessions. Medical experts call the closed-loop approach plausible and probably safe but unproven for sleep, and want randomized sham-controlled trials to show real-world benefit.
