Vagus nerve stimulation (VNS) is a treatment that uses electrical impulses to stimulate the vagus nerve. The ZenoWell Luna utilizes transcutaneous auricular vagus nerve stimulation (taVNS), which targets the branch of the vagus nerve closest to the skin surface, which is in the ear.
The vagus nerves are some of the longest nerves in the body, and controls our parasympathetic system (resting and digesting). They carry signals between the brain, heart, and digestive system, so when the signals are not working correctly, they can cause a lot of issues in the body. Some studies show that by stimulating the nerves, it can help treat conditions like epilepsy, depression, headaches, and chronic pain. With most of these studies, these devices are implanted and invasive.
Recently wearable devices, like the ZenoWell Luna, that stimulate the vagus nerves have become more popular. The Luna has 4 settings, each lasting 20 minutes with an adjustable intensity level.
