It's your body's built-in calm switch: it tells your heart to slow down, your breath to deepen and your whole body that it's safe to rest. Train it every day, and calm gets easier to reach.
The vagus nerve is the body's main line between brain and organs — involved in how you regulate stress, focus, and rest. Nervelo adds a small, deliberate signal into that same pathway.
Helps calm the body's stress response, so tension has less room to build.
Designed to help you wind down, so falling asleep feels easier.
A few quiet minutes to reset, whenever tension builds during the day.
Clears mental fog before deep work, so you can show up sharper.
Supports the body's natural recovery process after a demanding day.
Rests on your neck while you read, work, or wind down. Nothing to hold in place.
Every feature works out of the box, for good. Your calm doesn't need a login.
Two sessions a day, close to a month of use. USB-C when it's finally time.
Switch modes and adjust intensity without touching your neck. Pre-paired, no setup.
Nervelo delivers gentle, non-invasive stimulation to the vagus nerve pathway at your neck — the cervical route researchers use to study this technology.
A small amount of conductive gel on the contact points, so the signal travels cleanly.
Rest it around your neck. Hands-free — nothing to hold in place.
Select the mode and intensity with the included remote or the on-device button. Sessions run 20 minutes and end on their own.
4 modes · 9 intensity levels · controlled stimulation from 25 to 100 Hz
Before deep work — or against the afternoon slump.
One device, every moment of your day.






"I was tired of calm coming with a subscription. So we built a device that asks nothing of you — no account, no monthly fee, no hidden charges. We designed Nervelo drawing on the available clinical research on vagus nerve stimulation, to put the best of this technology within everyone's reach. Just a few quiet minutes, twice a day."

No. This model works entirely on its own — the included remote controls everything, and every function is also available on the device itself. No account, no pairing, no updates.
Nervelo delivers gentle low-frequency pulses (tVNS) to the vagus nerve area of your neck — the pathway your body uses to shift from "fight-or-flight" into "rest-and-digest." You feel a soft, comfortable tingling. Sessions are 20 minutes and end on their own.
The two metal contacts rest on the left and right sides of your neck, where you can feel your pulse. The band simply holds them in place, hands-free. Make sure both contacts touch your skin.
Yes, every session. The gel is what carries the stimulation to your skin: without it, you won't feel anything and it may seem like the device isn't working. Apply enough to fully cover each metal contact. If the sensation fades during the 20 minutes, the gel may have dried: add a little more.
Nervelo comes in two sizes, so measure your neck before you order: wrap a soft measuring tape around the middle of your neck. Small fits necks 12"–15.75" (30–40 cm) and Large fits 15"–19.7" (38–50 cm). Between 15" and 15.75"? Choose Small. Choose by neck size, not by gender: the right size keeps both contacts resting on your skin.
A soft, steady tingle on both sides of your neck at the same time. It isn't a massage or a strong pulse, and it should never feel uncomfortable. Start at a low level and go up one level at a time (there are 9).
For the best results, sit upright. If you lie down or lean your head on a pillow, you can push the metal contacts away from your skin. When they lose contact, you stop feeling the stimulation, even though the device keeps working.
Charge it fully with the included USB-C cable before your first session. About 1 hour of charging gives up to 25 days of use. If it turns off shortly after you turn it on, the battery is low and needs charging.
The device, a remote control, a USB-C cable, conductive gel, a travel pouch and a printed quick-start guide. Can't see the guide? Lift the black foam tray that holds the device. You can also follow our step-by-step guide online.
