Summary

This study aims to use the Apple Watch health metrics to assess short-term physiological responses in a randomized, double-blind, crossover real-world indoor purification intervention.

Conditions

  • Air Pollution Exposure
  • Heart Rate
  • Resting Heart Rate
  • HRV
  • SpO2
  • Respiratory Rate
  • Sleep

Interventions

BEHAVIORAL

Real Filtration

IQAir Atem X purifier with real filter (HyperHEPA) which is designed to remove PM2.5

BEHAVIORAL

Sham Filtration

IQAir Atem X purifier with sham filter which does not filter any PM2.5. When installed inside the purifiers, the sham filter produced the same appearance and sound as the real one, making the two interventions indistinguishable to participants.
