Traffic

 Vehicular traffic, especially traffic jams and long commutes can affect commuters in many ways. Loud honking, road rage and overspeeding can affect the person themselves and other commuters as well. ... Possible effects can include people opting for a job change due to the stress and fatigue caused by the daily commute.At a cognitive level, the sense of a lack of control, a feeling of helplessness and poor tolerance for frustration lowers one’s response inhibitive ability and one does whatever comes to their mind at that moment.

At a physical level, one may experience high blood pressure, a feeling of being on edge, a heightened activity in the Autonomic Nervous System (ANS, the part of the brain that’s responsible for controlling bodily functions which are not consciously directed, like breathing, heartbeat and digestion), and changes in body temperature. In the long run, the immune system’s ability to withstand pressure reduces.
