The science

A science-led approach grounded in research, trials, and clinical collaborations.

SleepCogni is built on over 10 years of research and development, a peer-reviewed clinical trial and a partnership with the NHS.

Active-Feedback technology

Effective results through personalisation

How it works

SleepCogni delivers gentle vibration cues through the Trigger. Each cue is answered with a press of the button.

This active engagement provides a calming distraction that helps the mind switch off by shifting attention away from worry and rumination that often interfere with sleep.

Personalisation

By incorporating behavioural and physiological signals collected through the Trigger, SleepCogni adapts each vibration cue in real time using patented Active-Feedback™ technology.

This creates a responsive feedback loop that helps guide the mind toward relaxation and the natural transition into sleep.

The science

Active-Feedback™ technology is developed from principles in cognitive neuroscience and behavioural sleep research.

It supports the natural process of settling into sleep by helping reduce cognitive arousal, without medication or screens.

Clinical trial results

SleepCogni conducted a randomised, placebo-controlled clinical trial, in collaboration with Sheffield Hallam University. The study involved 80 adults with chronic insomnia.

The peer-reviewed study, published in Frontiers in Sleep, demonstrated rapid and statistically significant improvements in Insomnia Severity Index (ISI) scores and sleep efficiency after seven nights of using SleepCogni’s patented Active-Feedback™ technology.

Participants reported difficulties such as falling asleep, waking during the night, or waking earlier than desired.

  • 4.2point reduction in insomnia symptoms (ISI)
  • 37%saw a clinically meaningful improvement in one week
  • +56minute increase in total sleep time
  • +11point improvement in sleep efficiency
  • 78%said SleepCogni was more effective than other methods
