The World’s First Personalized Sleep Solution

We’re proud to be leading the way with cutting-edge research for the next generation of sleep solutions. But we also know that means there’s some mystery around how Somnee works.

Here's a short guide highlighting everything you need to know.

A Quick Overview: How Somnee Works

Somnee leverages EEG+ and tACS to deliver first-in-class personalized neurostimulation scientifically backed to promote deeply restorative sleep.

  1. Our EEG maps your unique brainwaves as your brain begins unwinding for sleep.
  2. Our tACS delivers gentle electrical stimulation matched to your brain’s distinct sleep signals and activity.
  3. You enjoy longer, deeper, faster, and overall better sleep that energizes you through your days.

What’s EEG?
Electroencephalogram (EEG) technology reads patterns of electricity in your brain (AKA your brainwaves). EEG works like a microphone, receiving data without emitting anything.

What’s tACS?
Transcranial alternating current stimulation (tACS) is a type of transcranial electrical stimulation (tES). It emits low-level electrical waves in specific frequencies to enhance unique brain states, like sleep.

tES has been used for a range of health conditions and cognitive states, including:

  • Stroke rehabilitation
  • Depression & anxiety
  • OCD symptoms
  • Chronic pain relief
  • Memory
  • Parkinson’s
  • Focus
  • Sleep

Until Somnee, tACS techniques used a one-size-fits-all approach to neurostimulation…

Somnee's secret: Personalized tACS

A study published in Frontiers in Human Neuroscience found that, compared to fixed tACS, Somnee’s personalized tACS led to a 28% increase in sleep onset and an average of 18 extra minutes of sleep per night.

Insomniacs saw even more benefits, getting 33 extra minutes of extra sleep with personalized tACS.

Combined with findings from 1,800+ nights of sleep data and a 3-year study in our advanced sleep lab in Berkeley, Somnee’s patented approach has been found to:

  • Cut time to fall asleep by 50%
  • Reduce nightly wake-ups by 1/3
  • Increase total time asleep by ~30 min
