Sleep better.
Wake up earlier.

Somnison is a wearable sleep compression system. It detects when you're in deep sleep, then delivers gentle, timed ultrasound to help your brain clear waste faster—so you can get the full benefits of 8 hours in 6.

Mechanism

Three things happen while you sleep

01

Detect

Four dry EEG electrodes read your brainwaves in real time. When you enter slow-wave sleep, the system knows within 30 seconds.

02

Enhance

Low-intensity ultrasound fires in 1.5-second bursts, timed to your natural CSF rhythm. It helps push fluid through the brain's glymphatic channels when they're most open.

03

Wake

A simulated sunrise gradually brightens inside the mask. You wake up naturally, without alarms, feeling like you slept a full night—even if it was two hours less.

Peer-Reviewed

Built on published research

Every claim traces back to independent studies. No microbubble studies. No animal-only extrapolation.
