In the first real-world study, researchers noted that systolic blood pressure increased by 19mmHg in people driving on very congested roads compared with people driving on the same road in light traffic conditions (142mmHg vs 123mmHg).

They measured the blood pressure of drivers at a petrol station on a main road into Beirut, Lebanon, where traffic was at “walking speed with intermittent stopping” during weekdays but flowed freely at weekends.
