Non-invasive vagus nerve stimulation (VNS) devices, like the Truvaga gadget, offer stress relief and potential sleep improvement at a fraction of the cost of traditional VNS treatments used for epilepsy and depression. While these devices are attracting attention in the $8.3 billion neurostimulation market, experts caution that the science behind their effectiveness is still developing. The vagus nerve, a key component of the parasympathetic nervous system, plays a role in regulating various bodily functions, and stimulating it could influence mood by affecting neurotransmitters in the brain.
"The science is still very young," Timir Datta, assistant professor in the Institute of Bioelectronic Medicine at the Feinstein Institutes for Medical Research, told The Post.
"Vagus nerve stimulation pulls you out of that stressful physiologic state. It puts you into a more metabolically stable and healthy state," Dr. Peter Staats - chief medical officer of the neurostimulation company.
