See the results of our successful sleep pilot program.

The science behind Somnee has been rigorously tested and validated by the “dream team” of neuroscientists and researchers at StimScience. Leading up to the development of Somnee, we conducted a 3+ year sleep study in our sleep lab in Berkeley, CA and a home pilot with over 1,500 nights of stim sessions. 

Both our sleep study and our pilot were blind, controlled research studies that were overseen by our Scientific Advisory Board. The study designs were approved by an Institutional Review Board. Below, we summarize the findings from those studies. 

Lab Sleep Study

We conducted our sleep study with 167 adult participants over three years. We screened out participants with non-insomnia sleep disorders (e.g. sleep apnea, restless leg syndrome) and those taking sleeping pills or anti-depressants. Sleep sessions were a mix of morning and afternoon nap sessions, and overnight sessions. Each participant had at least two sleep sessions, one of which was a sham session (like a placebo – a session where they slept without the stimulation we were evaluating). Sleep activity was recorded using laboratory-grade EEG and EKG systems, and was scored by a certified polysomnography technician, using the same approach as any medical sleep lab.

The sleep metrics we measured to determine effectiveness were:

Response Rate

(% of participants that saw an improvement with our stim session)

Pilot Study

We conducted our pilot study with adult volunteer participants in the San Francisco Bay Area. Participants used prototype Somnee headbands and consumer-grade sleep trackers to track sleep sessions in their homes. There were a total of 55 participants and 1,814 nights of sleep sessions. 

One of the metrics we measured in our at-home pilot was the number of participants that increased their sleep duration using our patented personalized stim session versus a non-personalized stim session. This chart summarizes the results.

On average, participants in our pilot study increased their sleep duration by 30 minutes with our personalized stim sessions from their Somnee prototypes. We’ll share more results from our pilot study soon, once our paper on the results has completed peer review.
