Bazaar Team Backs 3 Vagus Nerve Devices After 3-Month Wellbeing Test

2 articles · Updated · Harper's BAZAAR · May 14

Three months of Bazaar testing found vagus nerve stimulation devices helped users feel calmer, recover from stress and, in several cases, fall asleep more easily.
Doctors cited in the report said consistent use can shift the body into parasympathetic “rest mode,” with users often noticing changes within 4 weeks and Yōjō reporting a 53.7% rise in parasympathetic activity and 31% HRV improvement in 2 weeks.
Bazaar’s top picks were Nurosym for simple in-ear use, Yōjō for sleep-focused sessions and app-guided modes, and Pulsetto for short neck-worn treatments aimed at anxiety and burnout.
The report stressed that higher intensity is not necessarily better and that the lowest effective setting should be used because skin resistance varies by person and day.
Non-invasive VNS was described as generally safe, but people with pacemakers or other implanted devices, pregnant users, and those with seizure histories or certain heart-rhythm disorders were told to seek medical advice or avoid use.

Are popular VNS wellness devices a safe biohack or an unregulated health risk?

Is hacking our nervous system the answer, or are we just treating the symptoms of a high-stress world?
