"I had been waking up at 3am for three years. I had tried everything. Two weeks in, the wake-up is basically gone. I wish someone had told me about this years ago."

Clinically Studied
The vagus nerve stimulation mechanism is backed by peer-reviewed clinical research, not wellness claims.
The Root Cause
If You Want to Fix Your Sleep, Your Hair, or Your Gut, You Have to Start With Your Nervous System
Your vagus nerve is the longest nerve in your body. It runs from the base of your brain through your neck and into your gut. Its job is to tell your body it is safe, to lower cortisol, slow your heart rate, and shift you out of stress mode into recovery mode.
When it is working properly, you sleep through the night. Your hair follicles get the blood flow they need. Your gut processes food without bloating. Your body repairs itself.
After months or years of sustained stress, vagal tone drops. The off switch stops working reliably. And everything downstream of it, your sleep, your hair, your digestion, your stress levels, starts to fail simultaneously. No supplement can fix this. The vagus nerve cannot be reached through your digestive system. It requires direct stimulation.
How Novu Works
The Direct Signal System, Three Things Happening Simultaneously in Four Minutes
When you wear Novu for four minutes, a gentle electrical pulse travels through the skin of your neck directly to the vagus nerve. No breathing technique required. No cold shower. No habit to maintain. The signal does the work your nervous system has forgotten how to do on its own.
01
Cortisol Reduction
Direct vagal stimulation suppresses the stress hormone responsible for the 3am wake-up, stress-related hair shedding, and chronic gut disruption. In a 2025 clinical study, cortisol dropped 47.5% over four weeks.
02
Parasympathetic Activation
Novu shifts your body from fight-or-flight into recovery mode, the state where sleep deepens, follicles receive blood flow, and the gut gets the signal to properly digest and move food through.
03
Vagal Tone Restoration
Consistent daily use rebuilds vagal tone, the baseline efficiency of the nerve, progressively over weeks. Like training a muscle. As tone improves, the body's ability to self-regulate becomes stronger and more automatic.
Clinical Evidence
The Numbers Behind the Mechanism
A 2025 peer-reviewed clinical study measured the effects of daily vagus nerve stimulation over four weeks in women experiencing chronic stress symptoms.

What to Expect
Most People Notice a Difference Before the End of Week One
Novu is not a sleeping pill. It is rebuilding a nerve function that has been depleted over months or years. Most users see meaningful improvement within the first week, with the full pattern change established by week three to four.
Days 1–3
First shift
Most users report feeling noticeably calmer in the evening after their first few sessions. Some notice improved sleep in the first three days.
Week 1
Sleep improves
The 3am wake-up becomes less frequent or disappears. Morning alertness improves. Many users stop reaching for melatonin by the end of week one.
Week 2–3
Pattern change
Cortisol begins to stabilise. Hair shedding starts to reduce. Gut symptoms ease. The body is spending more time in recovery mode and less in fight-or-flight.
Week 4+
Sustained results
Vagal tone is rebuilding. Sleep, stress, hair, and gut outcomes are all improving as a connected system. Most users continue daily use to maintain and build on results.
How It Compares
Novu vs. Supplements, Medications, and Other Approaches
Every other approach addresses one downstream symptom. Novu addresses the nervous system that controls all of them simultaneously.

FAQ
Common Questions
Novu delivers a gentle electrical pulse through the skin of your neck directly to the vagus nerve. This is called transcutaneous vagus nerve stimulation, or tVNS. When the vagus nerve is stimulated, it activates your parasympathetic nervous system, which tells your body it is safe to move out of fight-or-flight and into rest and recovery. This lowers cortisol, slows heart rate, and supports the systems that have been disrupted by chronic stress, including sleep, hair growth, and gut function. Four minutes a day is enough to begin rebuilding vagal tone over time.
Apply a small amount of conductive gel to both contact points on the device. Place the device on the left side of your neck, where the vagus nerve runs closest to the surface. Select your intensity level and start low, increasing gradually as you become comfortable. Use for four minutes. Most users find the evening works best, after the highest-stress period of the day. You can also use it in the morning or right before sleep depending on your routine.
Most users describe a gentle tingling or buzzing sensation on the neck at the contact points. At lower intensity levels it is barely noticeable. At higher levels it is more pronounced but should never be uncomfortable or painful. If it hurts, reduce the intensity. The sensation is similar to a mild TENS device. Many users report feeling their shoulders drop and their breathing slow within the first minute of a session.
Most users notice a shift in how they feel in the evenings within the first few sessions. Sleep improvements typically appear within the first week. The fuller pattern change, including reduced hair shedding, improved gut function, and sustained lower stress levels, develops over three to four weeks of consistent daily use. Novu is not a sleeping pill. It is rebuilding vagal tone that has been depleted over time, which happens progressively, not overnight.
Once daily is the recommended starting point, and this is what the clinical study protocol used. You should use it as part of your daily routine, ideally at the same time each day, for consistent results. Some users use it twice daily during periods of elevated stress. Once vagal tone has improved, some reduce to every other day for maintenance. Think of it like exercise, consistency matters more than intensity.
Novu is a general wellness device and is safe for most healthy adults. Do not use Novu if you have an implanted pacemaker or any other active implanted medical device, if you are pregnant, or if you have a diagnosed heart arrhythmia or epilepsy. If you have any other medical condition or are taking prescription medication, consult your doctor before use. The vagus nerve connects to the heart, so people with heart conditions should always seek medical advice first.
Yes. Novu is not a replacement for supplements or medications. It works at the nervous system level, upstream of the symptoms those products address. There is no known interaction between transcutaneous vagus nerve stimulation and common supplements such as melatonin, magnesium, or probiotics, or standard medications. Many users find they gradually need their supplements less as their vagal tone improves, but there is no need to change anything when you start.
No. Androgenetic alopecia, the genetic form of hair loss driven by DHT sensitivity, is a hormonal receptor issue and requires a different intervention. Novu addresses stress-related hair shedding, known as telogen effluvium, where cortisol and sympathetic nervous system dominance push hair follicles into a premature resting phase. If your hair loss started during or after a stressful period and came alongside other symptoms like disrupted sleep or gut issues, the stress-related mechanism is almost certainly involved alongside or instead of the genetic one.
A full charge provides approximately 7 to 10 days of daily four-minute sessions. Charging from empty takes under two hours using the included USB cable. A small LED indicator shows battery status. We recommend charging once a week as part of your routine so you never run low mid-session.
30 days, no questions asked. If you do not notice a meaningful difference within 30 days of daily use, contact us and we will refund you in full. You do not need to send the device back.
