Few sensations are as frightening as not being able to get enough air. Shortness of breath â known medically as dyspnea â is often described as an intense tightening in the chest, air hunger or a feeling of suffocation. Very strenuous exercise, extreme temperatures, massive obesity and high altitude all can cause shortness of breath in a healthy person. Outside of these examples, shortness of breath is likely a sign of a medical problem.
