Improving Indoor Air Quality Could Save YOUR Life
"Cost-effective ways exist to improve your indoor air quality that will reduce your COVID and flu risk, lower your cancer and lung disease risk, and eliminate headaches and sleepiness caused by poor ventilation. Maybe you’ve been sitting in church or listening to a lecture that, though provocative, sends you into a dozing dreamland, despite getting plenty of sleep the night before. Or maybe you’ve fought to stay awake during a long car ride. These experiences often have as their root cause a common factor – poor indoor air quality caused by a buildup of carbon dioxide because of poor ventilation. In addition to sleepiness, poor indoor air quality has been shown to reduce productivity, negatively affect test scores, and spread disease. Simple ways to improve your indoor air quality, like replacing furnace filters and running air purifiers, can have a huge impact on your health and quality of life."
I chat about the latest science on how harmful poor indoor air quality is, and what we can do to monitor and improve it.
