A traffic jam can cause stress. One of the stress triggers while driving during a traffic jam is impatience — having to wait for the traffic to move and dealing with the mistakes of other motorists on the road.
Aside from frustasi, a traffic congestion exposes to pollutants that can affect people’s lungs. Aside from chronic lung diseases, a research finds that air pollution can use blood pressure to rise and iflame the arteries, increasing heart attack and stroke risk.
