[Scientific Basis and Important Disclaimer]

We are committed to providing you with valuable references for a healthy lifestyle, based on a rigorous scientific approach. The data collected by the Lingxi YUEzhi ring and its App is analyzed using a series of algorithms based on public scientific research.

I. Scientific Principles of Core Functions

1. Sleep Analysis
Our sleep analysis feature is designed to help you understand your sleep patterns, and its methodology is built upon recognized scientific standards.

• Theoretical Basis: Our definitions of sleep stages such as “Deep Sleep,” “Light Sleep,” and “REM (Rapid Eye Movement)” follow the official guidelines of the American Academy of Sleep Medicine (AASM).
  (Reference: Sleep Classification According to AASM and Rechtschaffen & Kales: Effects on Sleep Scoring Parameters. PMC2635577)

• Technical Approach: The device estimates sleep stages using PPG (photoplethysmography) and motion sensors. The feasibility of this technical approach has been validated within the scientific community.
  (Reference: Automatic sleep-stage scoring based on photoplethysmographic signals. PMID: 32392540)

• Sleep Score: This is a comprehensive quantitative metric. Its model provides a holistic assessment of your total sleep duration, the balance of different sleep stages, and sleep continuity, offering you a consolidated snapshot of your nightly sleep quality.

2. Skin Temperature Trends
The device measures changes in your skin temperature during sleep via a built-in temperature sensor. This data can be used to observe your personal long-term body temperature rhythms and trends.
