Is Conference Room Air Making You Dumber?

schwit1 shares a report: At least eight studies in the last seven years have looked at what happens specifically in a room accumulating carbon dioxide, a main ingredient in our exhalations. While the results are inconsistent, they are also intriguing. They suggest that while the kinds of air pollution known to cause cancer and asthma remain much more pressing as public health concerns, there may also be pollutants whose most detrimental effects are on the mind, rather than the body. So can you trust the decisions made in small rooms? How much does the quality of air indoors affect your cognitive abilities? And as our knowledge of indoor air's effects grows, do we need to revise how we design and use our buildings? Buildings in the United States have grown better sealed in the last 50 years, helping reduce energy used in heating and cooling. That's also made it easier for gasses and other substances released by humans and our belongings to build up inside. Although indoor air quality is not as well monitored as the air outdoors, scientists and ventilation professionals have extensively monitored carbon dioxide indoors. Higher CO2 levels -- say, above 1,200 parts per million (ppm) -- often indicate a low ventilation rate. Worrisome substances emitted by new furniture, office supplies and carpets could be accumulating in the air.
