TORONTO — Muse today announced Deep Sleep Boost (DSB), a new sleep feature designed to help users sustain deeper, more stable slow-wave sleep. Powered by Muse S Athena, Deep Sleep Boost delivers targeted slow-wave sleep support using AI-driven neural signal models trained on large-scale EEG data. These models enable precise detection of slow-wave sleep and real-time timing of acoustic stimulation, addressing the brain’s most restorative sleep stage—closely linked to physical recovery, memory consolidation, and long-term brain health.

Many adults spend enough time in bed but still wake up unrefreshed. The issue is often not sleep duration, but insufficient depth. Deep Sleep Boost is designed to strengthen and stabilize deep sleep using EEG-guided, phase-timed sound cues, helping users wake feeling more restored and clear-headed.

“Helping people fall asleep is important, but sleep quality is what ultimately drives recovery,” said Chris Aimone, Chief Innovation Officer and Co-Founder of Muse. “Over the past several years, we’ve made sustained advances in EEG-based sleep modeling, combining improved signal processing, machine learning, and large-scale training data to better understand not just when deep sleep occurs, but how it’s structured. Deep Sleep Boost builds on that foundation, using adaptive, real-time brain models to precisely time sound cues and support deeper, more continuous slow-wave sleep rather than simply adding more minutes.”

that precisely timed acoustic stimulation during slow-wave sleep can meaningfully strengthen deep sleep. In one randomized trial, phase-locked sound cues increased slow-wave activity by nearly 50% and improved overnight memory retention by about 20%.

In a pilot study involving people with Alzheimer’s disease, nightly acoustic stimulation was associated with an approximately 60% increase in time spent in deep, slow-wave sleep.

Deep Sleep Boost translates this validated sleep science into a feature designed for consistent, real-world use at home. In beta testing, Deep Sleep Boost delivered measurable improvements in the structure of deep sleep itself, an aspect of sleep quality that matters more than simply increasing the total minutes spent in deep sleep:

How Deep Sleep Boost works

Article content

Muse S Athena, the world’s first consumer wearable to combine EEG and fNIRS, continuously monitors brain activity overnight. When slow-wave sleep is detected, Deep Sleep Boost delivers whisper-quiet, EEG & AI timed pink-noise synchronized to the brain’s slow oscillations to reinforce and stabilize deep sleep without waking the user.

Muse’s ability to deliver effective sleep interventions is built on years of EEG-guided sleep support already in use by consumers. Muse directly measures real-time brain activity during sleep, offering advanced sleep tracking powered by validated EEG-based AI models trained on longitudinal, real-world brain data.
