Difficulty winding down
Your mind or body may still feel alert after the day is over, making it harder to settle into sleep.
Vagus nerve stimulation designed to support better sleep.
Neuvago is a non-invasive vagus nerve stimulator designed to support calmer evenings, easier wind-down and better sleep. It delivers gentle, adjustable stimulation through an earpiece at the outer ear, with a dedicated Sleep mode and a 20-minute session.
Sleep is shaped by more than tiredness. Stress, mental activity and lingering nervous system activation can make it harder to move from alertness into rest, stay asleep and feel restored the next day.
WHEN SLEEP FEELS HARD
Sleep can be difficult even when you are tired.
Falling asleep and staying asleep require more than fatigue. Stress, an active mind and lingering physiological alertness can make it harder for the body to shift into rest.
Waking during the night
You may fall asleep but find it difficult to settle again after waking.
Light or restless sleep
Sleep may feel easily interrupted, shallow or less restorative than expected.
Tired but wired
You may feel exhausted while still feeling mentally active, tense or unable to fully switch off.
CLINICAL SLEEP RESEARCH
Randomized trials have reported positive sleep outcomes.
Two randomized sham-controlled trials in people with chronic insomnia reported greater improvements in sleep outcomes with active taVNS than with sham under the specific protocols studied.
RANDOMIZED SHAM-CONTROLLED CLINICAL TRIAL2024
taVNS and chronic insomnia
In 72 adults with chronic insomnia, active taVNS produced a 4.2-point greater improvement in PSQI sleep-quality scores than sham at week 8. Responder rates were 69.4% with active taVNS and 27.8% with sham.
Studied protocol: 30 minutes twice daily, five consecutive days per week, for eight weeks.

taVNS and sleep quality
In 40 participants with chronic insomnia, active taVNS produced significantly greater improvements in sleep quality and insomnia severity than sham after six weeks. The study also reported positive findings for total sleep time and quality of life.
Studied protocol: 30 minutes daily for six weeks.

NEUVAGO SLEEP MODE
A simple 20-minute routine for calmer evenings.
Neuvago delivers gentle, adjustable stimulation through an earpiece at the outer ear. Its dedicated Sleep mode uses a slow, continuous stimulation pattern designed for evening wind-down and rest.
Every Neuvago mode runs for 20 minutes and ends quietly.
Prepare and position the earpiece
Lightly moisten the supplied earpiece with conductive gel or water, then place it in the correct position in the left ear as described in the User Manual.
Select Sleep mode
Choose the dedicated Sleep mode and begin the 20-minute session as part of your evening wind-down.
Adjust the intensity
Increase the intensity gradually until the stimulation feels strong and noticeable but remains comfortable and does not hurt. Higher intensity does not mean better effect.
