Are Sleep Tracker Rings Accurate? What the Science Says

How Smart Rings Measure Sleep

Sleep tracker rings use photoplethysmography (PPG) sensors to monitor blood flow, heart rate variability, and movement patterns. Advanced algorithms analyze this data to determine sleep stages and quality metrics.

  • PPG sensors track heart rate and blood oxygen levels
  • Accelerometers detect movement and sleep position
  • Temperature sensors monitor body temperature fluctuations
