Comparing the scientific research behind popular Vagus Nerve Stimulation devices
"...you can select the device that best meets your needs. For us, Nurosym emerged as the clear winner of our evaluation." (Health Science Institute)
Nurosym vs. Other Methods Associated With Vagus Nerve Activation
Social media trends claim meditation, ice baths, and breathing exercises stimulate the Vagus Nerve, however these effects are unproven and rarely targeted. The AVNT™ device offers a precise, medical-grade solution instead. Compare more below.

700+studies well-documented and scientifically reviewed |
Effectiveness supported by scientific studies |
LowThe risks of cardiovascular stress / muscle mass reduction / adrenaline addiction, often outweigh the potential gains. |
MixedMixed results with 67% of studies not assessing risks, and 25% of participants reporting prolonged negative effects |
LowPartial research has shown it as a technique that can stimulate the parasympathetic system though more studies are needed |
HighSupported by scientific studies as effective for vags nerve stimulation and stress reduction. |
HighStrong scientific evidence; use for a variety of medical symptoms (headaches and depressive states). |
Targeted vagus stimulation and effect predictability |
Stimulation is broad, and effects are unpredictable with significant individual variation. |
Variable stimulation; effects dependent on individual practice, difficult predictability. |
MixedIndirectly may stimulate the vagus nerve, although not precise. |
MixedPartially targeted stimulation, it may either increase sympathetic activity or enhance parasympathetic activity depending on the type. |
Precise and predictable in targeting the vagus nerve with consistent therapeutic outcomes. |
Direct mode of action |
Activates the SNS and stress response, triggering on adrenaline rush and cold shock response. |
Affects the PNS and may promote relaxation, but negative emotions can trigger an SNS response, which may lead to increased stress. |
Influencing the PNS through vocal vibration. |
Some techniques may modulate the autonomic nervous system by activation the vagus nerve, reducing stress, and promoting relaxation. |
Direct electrical stimulation of the vagus nerve, affecting brain regions related to mood, pain, and autonomic function. |
Easy to perform |
Requires controlled access to cold water and supervision for activity. |
Requires learning a proper technique, quiet, comfortable space and time. |
Easy and accessible to perform anywhere |
MixedRequires choosing the right technique, involves minimal effort and can be performed anywhere |
New non-invasive devices are easy to use, portable, without supervision. |
Can be combined with other activities |
Generally requires focused time and setting |
MixedRarely incorporated into other activities unless consistently practiced, focus required. |
MixedCan be done while performing other low-intensity tasks, although social acceptance varies. |
Generally requires focused time and setting. |
Can be worn and used during daily activities without requiring focused attention. |
