Masimo Reveals Advanced Sleep Analysis for W1 Watch

Masimo has announced a new sleep analysis feature for its W1 Sport advanced health tracking wearable.

The Sleep Halo feature provides overnight sleep data tracking with over 70,000 daily measurements of continuous health data. It leverages the company’s continuous SET pulse oximetry and machine learning to offer insights into sleep quality, including overall timing, sleep stage duration, periods of rest and wakefulness, and episodes of desaturation.

The Sleep Halo score—an algorithmic calculation for overall sleep quality—is then displayed on a companion smartphone app. The sleep score and analysis will be available in all future Masimo wearables, including the company’s upcoming Freedom watch and band.

Masimo W1 Sport owners can soon update their watch’s firmware and Masimo Health app to add the sleep tracking function. The company advised that the W1 Sport watch and Sleep Halo are for general health and wellness purposes.

“We’re truly excited to launch Sleep Halo for Masimo W1 Sport. For 35 years, Masimo has been dedicated to using breakthrough engineering to help improve lives,” said Masimo founder and CEO Joe Kiani. “Masimo W1 is unique among wearables in being able to continuously measure the wearer’s SpO₂ and PR – and that gives us an opportunity to provide a truly informed, robust analysis of how one sleeps. As always, we are committed to providing scientifically backed measurements, which are based on our unmatched, accurate technology, not ‘tarot card logic’ novelties. We benchmarked Sleep Halo with EEG to confirm its stages of sleep are comparable to sleep analysis. We hope that with this new scientifically based Sleep Halo, our customers can improve their sleep hygiene, which has been shown to improve life.”
