- Indoor air pollution is understudied despite its high mortality and economic impact globally.
- A 2-week cohort study monitored indoor air quality and symptoms in asthma and COPD patients.
- 43.3% of participants experienced PM2.5 and PM1 peaks above the upper control limit, mainly between 6 pm and 9 pm, likely due to cooking.
- Smokers had higher average pollutant levels than non-smokers.
- Participants experienced 4-6 pollutant peak periods exceeding WHO 2021 air quality guidelines on average.
- No statistically significant association was found between PM2.5 and asthma symptoms, though a weak visual relationship was observed.
- Human activities significantly influence indoor air quality, suggesting behavioral interventions could help optimize it.
