Overview

Randomized trial examines sleep architecture in Black adults, revealing implications of meteorological factors.

Key Points

  • This study investigates how meteorological factors affect sleep architecture among Black adults in urban settings.
  • Analyzed data from 363 participants using the Sleep Image Ring for sleep assessment.
  • Linked participant location data with NASA POWER datasets for meteorological exposure analysis.
  • Assessed the impact of temperature, humidity, precipitation, and cloud cover on sleep quality.
  • Each 1-unit increase in total precipitation correlated with a 0.20 percentage point rise in REM sleep (β = 0.204, p = 0.009).
  • Greater cloud cover related to increased REM sleep percentage (β = 0.038, p = 0.029) and decreased stable NREM sleep (β = -0.112, p = 0.031).
  • Higher humidity associated with a significant increase in unstable NREM sleep (β = 0.344, p = 0.039).
