The 4-Minute Solution to 3AM Wake-Ups
Help your nervous system shift out of alert mode and into rest & recovery with science-backed vagus nerve stimulation, so you can sleep through the night and stop the 3AM wake-ups.
“Sleep maintenance insomnia often reflects a nervous system still on alert. Non-invasive vagus nerve stimulation helps shift patients into rest-and-recovery mode. Most of mine then sleep through the night.”
Understanding Nighttime Awakenings
The Science Behind Waking Up at 3AM
The body can be physically exhausted enough to fall asleep while the nervous system remains stuck in fight or flight. Then, around 2–4AM, the human body gradually releases cortisol to prepare for waking later in the morning. But when the nervous system is already in an alert state, that natural rise can be interpreted as a biological emergency — jolting the body fully awake.
The Vagus Nerve
The Vagus Nerve Is The Body’s Off Switch For Fight Or Flight.
The vagus nerve is your body's main communication line to the brain. It's the longest cranial nerve in your body that’s constantly shifting between “fight-or-flight” (sympathetic) and “rest-and-digest” (parasympathetic) modes.
When stress is frequent or you never fully recover, your system can get stuck in “fight-or-flight” making it harder to relax even when you want to. Stimulating it sends signals toward the brain that increase parasypathethic activity, shifting the nervous system into rest and recovery.
Introducing Nervostim
Calm The System That's Waking You Up.
Nervostim uses gentle, non-invasive electrical stimulation through the neck to stimulate the vagus nerve and help shift the nervous system toward rest and recovery before sleep.
Why This Matters At 3AM
Your Nervous System Stays At Rest As Cortisol Rises.
With the nervous system shifted into rest and recovery, the natural rise in cortisol toward morning won’t trigger the exaggerated alert response that jolts the body awake. Instead, the nervous system remains in its resting state as cortisol gradually rises toward morning.

Stay asleep for longer
Helps support a calmer nervous system state throughout the night, reducing the alert response that can interrupt sleep.
Spend less time awake at night
Supports more continuous sleep instead of spending hours awake after an early morning wake-up.
Support overnight recovery
Helps your body remain in a state that's more conducive to rest and recovery throughout the night.
Wake feeling more restored
More continuous sleep means more opportunity to wake with the energy and clarity you need for the day ahead.

Frequently Asked Questions
Still Have Questions?
Everything you need to know before getting started with Nervostim.
Nervostim delivers gentle electrical pulses through the neck. Most people experience the stimulation as a mild pulsing or tingling sensation — often described as gentle waves of calmness as the session progresses. You can adjust the intensity in the app to find a level that feels comfortable for you.
There’s no complicated routine to learn. Position Nervostim comfortably, and connect it to the Nervostim app. From there, choose your program and start the session through the app.
It can vary from person to person, so you shouldn't expect everyone to respond on exactly the same timeline. Nervostim's existing guidance gives a range of 1–60 days: some people may notice an effect within the first few days, while for others it can take several weeks of consistent use.
Nervostim uses low-energy stimulation designed for everyday well-being use. There are some situations where it shouldn't be used, however. Nervostim isn't recommended for people with active implantable medical devices such as pacemakers, hearing-aid implants, or other electronic implants. If you have one of these devices, you should speak with your healthcare provider before using Nervostim.
Once you've purchased Nervostim, there isn't a required monthly subscription to keep using it. The core app and stimulation programs are included with the device, so you're not signing up for another recurring monthly expense just to continue your sessions.
You don't have to know with certainty that Nervostim will be right for you before trying it. You have 30 days to use it and decide for yourself. If it isn't right for you, you can return it in its original packaging within that period for a refund.
