Enhancing Muse’s AI sleep platform: Deep Sleep Boost
TL;DR
-
Muse is launching the new Deep Sleep Boost (DSB) feature which is a form of Deep Sleep Stimulation (DSS) (coming January 2026)
-
DSB helps you sustain longer deep sleep by delivering EEG-timed sound cues (like pink noise) during deep sleep stages.
-
DSB is available for all Muse S Athena users at no added cost
-
Muse will be launching more features for the AI Sleep Platform – creating a full end-to-end sleep cycle solution for users
Following the launch of our AI Coach: Enso, Muse is further extending the integration of AI into the night. Introducing the Deep Sleep Boost (DSB) feature, the newest addition to our AI sleep platform, turning Muse S Athena into an active sleep therapy tool, guiding your brain toward deeper, more restorative slow-wave sleep (N3) instead of simply reporting how well you slept.
In other words, Muse is bringing the type of closed-loop acoustic stimulation previously seen in sleep labs, right to your home.
What is Deep Sleep Stimulation?
Deep Sleep Stimulation uses EEG-guided closed-loop neurostimulation to support the most restorative phase of sleep: slow-wave sleep, or the N3 stage. Unlike passive sound machines, DSS precisely “listens” to your brain activity in real time and delivers whisper-quiet, EEG-timed pink noise cues synchronized to your natural slow-wave rhythms.
In short, traditional trackers are like thermostats that tell you how cold or warm the room was overnight. They show you your sleep stages, but they do not intervene. On the other hand, DSS is more like a smart climate system for your brain. It monitors your sleep stages and actively adapts to your real-time sleep.
How does Deep Sleep Stimulation work?
Unlike simple sound machines that play noise all night, Deep Sleep Stimulation responds works as a closed-loop system that “listens before it speaks.”
-
Real-time detection: Muse’s clinical-grade EEG sensors continuously monitor your brain as you sleep and detect when you enter slow-wave sleep.
-
EEG-timed audio cues: When slow-wave activity is detected, DSS delivers subtle, phase-locked pink noise pulses that reinforce and amplify the brain’s natural slow oscillations.
-
Reinforcement and stabilization: These cues help guide your brain towards deeper, more stable slow-wave patterns, extending this key stage of recovery with minimal disturbance.
The benefits
Unlock the full potential of your rest:
-
Deeper, more restorative sleep: Research shows precisely timed pink-noise cues can boost slow-wave sleep power, promoting faster brain recovery and longer deep sleep phases.
-
Enhanced cognitive function: Slow-wave sleep is critical for memory consolidation and clearing brain toxins. DSS supports improved next-day clarity, alertness, and long-term brain health.
-
Safe and personalized: With a Sleep-Safe Design that includes an arousal watchdog, DSS pauses audio cues if signs of disturbance are detected, preserving sleep continuity. Users can customize intensity and timing, with premium users able to layer DSS with other sound tools.
How does Deep Sleep Stimulation work within the enhanced AI Sleep Platform
Deep Sleep Stimulation works alongside Muse’s existing Digital Sleeping Pills™ and the upcoming Smart Alarm, which wakes you during lighter sleep phases, to create a full end-to-end sleep cycle solution.
Digital Sleeping Pills™ (DSPs): helps you fall asleep naturally
-
Delta wave neurofeedback to keep you asleep
-
Real-time EEG-guided sleep journeys
-
55% users fall asleep faster
-
Improves sleep quality by 20%
Smart Alarm (Coming soon): helps you wake better and start the day sharper
-
EEG-Informed optimum wake window.
-
Gentle Wake Sequence
-
Reduced Grogginess
Together, these features form a full end-to-end sleep cycle solution:
Settle faster → Sleep deeper → Wake clearer
Why does deep sleep matter?
Deep slow-wave sleep is where the brain does some of its most important maintenance.
-
Memory consolidation: Your brain replays and stabilizes important memories.
-
Metabolic & immune support: Deep sleep is tied to immune function and metabolic regulation.
-
Brain clean-up: Slow waves are linked to the “cleaning” of metabolic waste in the brain, which is increasingly studied in the context of long-term brain health.
Many adults get enough hours in bed but still feel unrefreshed because they do not get enough high-quality deep sleep. By specifically targeting this stage, Deep Sleep Stimulation aims to upgrade the “quality per minute” of your sleep.
Try Deep Sleep Boost
Instead of only asking, “How did I sleep?” you can start asking, “How deeply can I train my brain to rest?”. Here’s how you can try it on your own.
