Sitting in traffic can certainly be infuriating enough to raise your blood pressure. But new research shows that traffic can raise your blood pressure and put your heart at risk in a more direct way - by exposing you to the pollution in exhaust fumes...
...near a local highway. People who breathed in polluted air registered higher blood-pressure readings a short time after exposure, compared with those who breathed filtered air, and their blood vessels showed impairment as long as 24 hours later. Such prolonged hypertension is a known risk factor for both heart disease and stroke. (Read "The Year in Medicine 2008: From...
...findings, published in the journal Hypertension, offers a potentially new understanding of how pollutants can affect the heart. While previous studies have linked bad air - specifically, air laden with fine particulates smaller than 2.5 microns in diameter - with higher rates of heart disease and stroke, it wasn't clear exactly how the particulates did their damage. Nor was it clear which of the many components of urban air were the most hazardous - the fine particulates from burning fossil fuels that come from exhaust pipes, or the ozone gases that permeate most densely packed city streets...
Brook's data suggest that particulates are more active players in heart problems than ozone, and that two different processes may be occurring as we inhale unclean air. First, the fine matter triggers changes in the central nervous system, causing a switch from the more controlled regulation of body processes to a more instinctive, automatic fight-or-flight response. This revs up the heartbeat and causes blood pressure to spike as the body may be responding to the presence of foreign, potentially dangerous particles in the air.
