Bring a vagus nerve stuck in fight-or-flight back into calm, in 4 minutes a day.*
Still waking at 3am with your heart pounding, wired and exhausted at once, even though the bloodwork came back "normal"? That is a vagus nerve stuck in fight-or-flight.
Novu is a transcutaneous vagus nerve stimulator. It sends a gentle pulse to the point on your neck where the vagus nerve runs closest to the skin, to switch your body out of fight-or-flight and rebuild vagal tone over time.
What Novu does:
The breathing, the humming, the cold showers, the supplements. None of it is fake. They all reach the vagus nerve from the outside. They knock, and a healthy nerve answers.
But after years stuck in fight-or-flight, the nerve loses its tone. It stops answering the knock. So every forced breath was you pounding harder on a door that wasn't opening.
That's the part no one explains. Pounding on it doesn't calm the nerve. It irritates it. Which is exactly why you got more sensitive, not less.
You didn't fail the method. The method couldn't reach a nerve that had gone too quiet to hear it. That's the one piece nobody handed you.

The vagus nerve runs on electrical signals. That's how it tells your heart to slow, your gut to settle, your body to stand down from alert. Everything you've tried reaches it the long way around, from the outside. By the time the signal gets to the nerve, it's faint, if it lands at all.
Novu sends a small, precise pulse to the point on your neck where the nerve sits closest to the skin. It doesn't wait for the nerve to answer a knock. It speaks to it directly, in the one language it still responds to. Used daily, that rebuilds vagal tone the way consistent training rebuilds a muscle.
If you tried an ear-clip device and felt nothing, this is why it's different. The clip pulses at the ear and hopes it carries. Novu sits on your neck, on the main trunk of the nerve, where the signal actually lands. Same principle as the vagus implants used in clinics, delivered through the skin instead of under it.


Sit it on the left side of your neck, where the vagus nerve runs closest to the surface.

Hold the button to begin a four-minute session. That's the whole timer.

Tap to raise or lower it until it feels like a steady, gentle pulse. Most people use it in the evening.
Novu uses transcutaneous vagus nerve stimulation, one of the most researched areas in nervous-system science, with hundreds of published papers behind it. A few worth knowing about:
In adults 55 and over, 15 minutes of daily stimulation for two weeks raised vagal tone and improved measures of sleep, mood and quality of life, with the biggest shifts in people whose systems were most stuck in "fight-or-flight."
Bretherton et al., Aging, 2019 · PMC6682519Stimulating the vagus nerve through the skin blunted the cortisol spike the body produces under acute mental stress, the same hormone that drives the 3am wake-up.
Transcutaneous auricular VNS, acute-stress study · PMC11815478In a double-blind, sham-controlled trial, stimulation at the neck reduced the body's sympathetic "fight-or-flight" response to stress.
Cervical tcVNS, double-blind sham-controlled trial · PMC7739181In a randomized controlled trial in people with primary insomnia, transcutaneous vagus nerve stimulation improved sleep quality over the course of treatment.
Primary-insomnia RCT, Brain Sci., 2022 · PMC9599790These studies look at transcutaneous vagus nerve stimulation as a method, not the Novu device specifically. Novu is a general wellness device. It is not intended to diagnose, treat, cure, or prevent any disease, and individual results vary.


honestly i bought this fully expecting to return it. i've wasted so much on breathing apps and magnesium and one of those ear clip things. first night i felt a soft buzz and thought yep, placebo, here we go. somewhere in the first week i slept straight through to my alarm. three weeks now and the 3am thing has basically stopped. it's not magic, i still use it every night, but it's the only thing that's touched it.

i've been a bad sleeper my whole adult life. not insomnia exactly, more like i'd doze all night and never actually drop. got it for sleep, wasn't expecting much. the sensation is way gentler than i thought. about ten days in my husband pointed out i'd stopped getting up in the night. i hadn't even noticed. that's when i believed it.

wired and exhausted at the same time, if you know you know. my heart would just start going in the evening for no reason. i do four minutes after dinner now and i can feel my shoulders actually come down. it didn't fix everything overnight, but the evenings stopped being a fight.

came for the sleep, did not expect anything to happen with my stomach. i'd had bloating after basically every meal for years and just figured that was me now. a few weeks in it quietened right down and i wasn't even using it for that. still a bit stunned about it.

two different doctors told me it was stress and my age and to try a gratitude journal. cool, thanks. i'd already done the yoga, the cold showers, the whole drawer of supplements. this is the first thing that did something i could actually feel. wish i'd found it two years and a lot of money ago.

bought one, then ordered a second for my sister because she'd been worse than me. now we text each other "did you do your four minutes." sounds silly but we both sleep better than we have in years. get the two pack, you'll end up wanting it anyway.

for about three years i'd wake at 3am like clockwork, heart going, then drag through the next day wired and exhausted. i'd tried the breathing, the magnesium, all of it. now i do my four minutes after dinner while the kettle's on, every night. about two weeks in i slept through for the first time. it's just part of my evening now and i don't dread bedtime anymore.

Newcomers, start with the 2x. The complaint we hear most? One is never enough. So many of our customers, the second they feel like themselves again, they buy a second for a daughter or a best friend to make sure she never loses those years the way they almost did.
