According to the work of Inserm and the Sorbonne University, it only takes a few minutes of exposure to air pollution to observe an increase in blood pressure. The phenomenon was found in all 221 study participants, all of whom were healthy.
Their blood pressure increased with each daily trip through the streets of Paris. One of the pollutants responsible for voltage peaks is at the exit of car exhaust pipes. This explains why the participants, during their travels, were exposed to this pollutant.
