Carbon monoxide -- the silent calmer?
Date:11/8/2011

xtent their experiences were stressful, and their input was corroborated with data taken from sensors that measured heart rate and pollutant levels. Noise pollution emerged as the most significant cause of stress.

The most surprising find of the study, says Prof. Schnell, was in looking at levels of CO that the participants inhaled during their time in the city. Not only were the levels much lower than the researchers predicted -- approximately 1-15 parts per million every half hour -- but the presence of the gas appeared to have a narcotic effect on the participants, counteracting the stress caused by noise and crowd density.

Turn down the volume

The results showed that living in a major city might not have as negative a health impact as the researchers were expecting. Though participants exhibited rising stress levels throughout the day, CO had a mitigating influence, and extended exposure to the chemical had no lasting effects.

The study's next step is to investigate how environmental loads impact the more vulnerable segments of the population, such as infants, the elderly, and those with medical conditions such as asthma. "We would be able to tell more accurately under what conditions vulnerable people shouldn't go out, and more importantly, identify areas that are still safe, helping to increase freedom of movement," notes Prof. Schnell.

But for now, urban dwellers can all contribute to making their environment a less stressful one by turning down the noise, he suggests. The findings indicate that most of the noise in an urban landscape is generated by human activity, and if individuals made an effort to reduce the noise they were making, they could help to reduce the environmental load placed on their neighbors.
