A scientific study has revealed that exposure to polluted air may increase the risk of developing obstructive sleep apnea, a condition in which breathing periodically stops during the night.
Researchers reached this conclusion after analyzing health and sleep data from over 4,000 adults and comparing it with data on pollution levels in their homes. The analysis showed that higher concentrations of fine particulate matter in the air are associated with an increased likelihood of developing obstructive sleep apnea. Specifically, higher levels of PM2.5 over a month were associated with an approximately 14% increased risk. Larger particles (PM10) also showed a consistent association with sleep disturbances, particularly with prolonged exposure.
Furthermore, high levels of carbon monoxide were associated with an increased risk of developing sleep apnea after exposure for several months. In contrast, other pollutants, such as nitrogen dioxide and ozone, did not show any statistically significant association after taking other factors into account.
Researchers indicate that even moderate levels of air pollution can affect sleep quality and health. The findings highlight the importance of controlling pollution levels, especially given that sleep apnea is linked to an increased risk of cardiovascular disease and cognitive impairment.
