When\u2019s the last time you gave your vagus nerve some attention? Thought so. <\/p>\n If you\u2019re au fait with all things wellness, you\u2019ve probably encountered it before. The vagus nerve is a bit like the body\u2019s M1, acting as a superhighway between your brain, major organs and gut. It relays signals that control relaxation, digestion and overall balance levels. In short, what happens in vagus\u2026 affects your entire nervous system.<\/p>\n 2025 has seen a wave of new wellness tech<\/a> designed to stimulate the vagus nerve and unlock better sleep, lower stress and higher levels of energy, naturally. The Netflix wellness docuseries Don\u2019t Die, which focused on multimillionaire Bryan Johnson\u2019s longevity journey, also spiked interest in vagus nerve stimulators<\/a> (VNS). <\/p>\n Y\u014dj\u014d<\/a> is the latest of such gadgets to emerge onto the market, designed to restore inner balance in people who feel besieged by stress. <\/p>\n When I met founder Waldi Hoon ahead of y\u014dj\u014d\u2019s UK launch, she explained that our primitive hardware can\u2019t differentiate between stressor levels \u2014 emails, bills, an impending visit from the in-laws \u2014 so the sympathetic nervous system, responsible for fight or flight, goes into overdrive. It\u2019s always on, chugging away in the background, rarely giving the opposing parasympathetic system time to \u2018rest and digest\u2019; that is, help you relax, reset, or heal. It means a low level of stress or panic feels omnipresent, forever lurking in the periphery. This could manifest in poor sleep, exhaustion, raised blood pressure and inflammation, leaving you vulnerable to illnesses or burnout. <\/p>\n There are ways to even the keel, from meditation and breathwork to gentle yoga. The problem there is that they all require blocking out time in your schedule, which can be scarce in the first place or leave you guilt-ridden when you\u2019re forced to skip sessions.<\/p>\n Y\u014dj\u014d<\/p>\n In some ways, y\u014dj\u014d<\/a> is the lazy person\u2019s route to descending from the summit of Mount Stress. The non-invasive earpiece can be worn while you\u2019re working, travelling or watching telly, delivering inner equilibrium with barely any effort on your part. <\/p>\n How does it work? The device gently stimulates the auricular branch of the vagus nerve in the outer ear through electrical pulses, stirring the body\u2019s natural rest-and-digest response, helping you relax while boosting anti-inflammatory processes. <\/p>\n I confess, I am a bit of a sceptic when it comes to wellness products, but if this could bring my shoulders down from up around my ears, it was worth a shot. The last thing I expected was that I would love y\u014dj\u014d so much that it now lives under my pillow, so I never miss a nightly session. <\/p>\n The clinical-looking device<\/a> works through an earpiece attached to the remote-style stimulator, which in turn, connects to a companion app via Bluetooth. <\/p>\n It uses tailored programs, biotech, wellness tutorials and support from real experts to tweak your treatment. Everything comes packed into a small hard-cased travel pouch, which can be slung into a weekend bag or tote. <\/p>\n After a few in-app set-up questions, you\u2019re prompted to do a face scan, or a \u2018healthy selfie\u2019 using your phone\u2019s front camera. Lasting 30 seconds in good light while you remain still, this captures things like your heart rate, blood pressure, stress index and parasympathetic activity, all from tiny fluctuations in facial colour and movement. <\/p>\n Next, you\u2019ll position the earpiece in a fold in your ear (always the left side), pick your mode \u2014 pick between Energy, Relax, Sleep and Stress \u2014 twiddle the intensity (it goes up to 30) and boom, your 30-minute timer will begin. Once the countdown is over, you\u2019ll be asked for another face scan, so you can compare before and after metrics. <\/p>\n Y\u014dj\u014d\u2019s VNS<\/a> can be used without the app, but using both is a helpful way to chart your stress levels. Plus, you have access to tons of other relaxation-aiding content, like breathwork how-tos, simple yoga moves, and a health coach who chips in with tailored advice and tips when reading your reports. <\/p>\n yojo<\/p>\n The kit comes with an application gel, which you should apply to the tip of the earpiece. I barrelled in without it for my first session, and the stimulation was, if not exactly painful, certainly irritating. Two weeks in, and I fastidiously apply the solution, so now the only real sensation is a very faint buzzing outside my left ear and dull pressure, like you\u2019d get from wearing earbuds. <\/p>\n Do intensity levels impact the results of a session? \u201cThe intensity is personal and has no impact on the efficacy of the stimulation,\u201d Hoon assures me. \u201cSome people use 4, some 15 \u2014 the outcome is the same. It\u2019s your brain doing the good work, we\u2019re just waking up the nerve and tricking the brain into a rest state. You just need to be able to feel it\u201d.<\/p>\n![](\"https:\/\/www.newsbeep.com\/il\/wp-content\/uploads\/2025\/11\/yojo-vns-device-lifestyle-pic.jpeg\")
