A new study conducted by the Harvard School of Public Health and Brigham & Women’s Hospital has discovered a link between air pollution and breathing-related disruptions during sleep. Analyzing data from 3000 people, the researchers found that incidents of sleep apnea and low levels of oxygen during sleep rose as the temperature increased during all seasons of the year. More incidents of sleep-disordered breathing were also found during the summer months when air pollution was high. The findings suggest that reduced exposure to air pollution may decrease the incidents and severity of sleep disruptions.
