Anxious drivers were more exhausted after their drives, according to new research UH Professor of Computational Physiology Ioannis Pavlidis designed research to capture how driving can stress out some drivers, while others remain cool Admit it: Daily commutes – those stops, the starts, all that stress – gets on your last nerve. Or is that just me? It might be, according to a new study from the University of Houston’s Computational Physiology Lab. UH Professor Ioannis Pavlidis and his team of researchers took a look at why some drivers can stay cool behind the wheel while others keep getting more irked.
