New Ear-Worn Device Targets Vagus Nerve to Ease Anxiety, Fatigue and Inflammation

Nurosym is an ear-worn gadget that applies low-level electrical impulses to a vagus-nerve branch accessible through the outer ear. Parasym, the developer, points to over 60 finished clinical investigations—some with placebo groups—that showed reductions in anxiety symptoms, fatigue, and markers of inflammation, as well as enhanced sleep. The device is marketed as non-surgical and without implanted components, aiming to influence the parasympathetic “rest-and-digest” system.

Its website clarifies that it does not diagnose, treat, cure or prevent disease and should not replace professional medical advice. Nevertheless, some users claim it improves mood, eases stress, aids sleep, and even alleviates persistent pain and gut issues. Pricing and purchase details are available on the Nurosym site.
