Poor indoor air quality slows down metabolic rate of office workers

A re-analysis of a study was made : it concerned 10 groups of 6 female subjects performing office tasks at their own pace during several hours exposures to 6 different air quality conditions. That re-analysis showed that CO2 produced by subjects at each air quality level was affected by air-quality. A change in breathing pattern or a slow down of work rate in polluted air would reduce both metabolic rate and thus the CO2 production rate.
