0189 Particulate Matter 2.5: Examining How Its Exposure Affects Perceived Sleep Quality and Electroencephalography Based Sleep Metrics

Abstract Introduction Individuals are exposed to various air pollutants every day, both when they inside and outside. Poor quality can negatively impact an individual’s sleep quality, especially the individual has been Particulate Matter 2.5 (PM2.5) which adversely affect human health due its ability penetrate into a body easily. Methods We examined how PM2.5 exposure impacts perceived metrics. 11 individuals (7 Female, 4 Male) with average age 34.18±10.24 years participated where each participant lived in simulated one-bedroom apartment unit located Rochester, MN for 20 nights total over weeks. Participants wore EEG-based headband (Dreem) measure metrics completed surveys assess fatigue level weekday after woke up. Air including was monitored units from sensors participants outside using portable research grade monitor paired GPS. Total calculated day by multiplying concentration 6 liter/min of inhalation rate duration (min). excluded less than 5 hours duration. One who reported poor 70% time also excluded. Results had 58.2μg±63.8 during until went bed 0.8μg±2.6 sleep. Because there minimal night exposure, only correlated measures. There no significant effect on efficiency, onset latency, wake onset, as measured Dreem headband. modest but rated poorer (r(141)=.17, p=.042) higher levels (r(141)=.26, p=.002) next morning. Conclusion These findings suggest acute were not high enough did one’s Future studies should examine longer period whether is chronic Support (if any)
