Running running to lung pain but hold on for a while may be due to the breathing rhythm and the pace of the movement to cooperate with each other and adapt to each other after the lungs have enough oxygen after the pain relief. If the breathing is uneven during running, and more energy needs to be consumed after running for a period of time, there may be insufficient oxygen in the lungs, accelerating the breathing rate as well as the frequency of oxygen exchange, and the air friction in the respiratory tract increases, which may damage the mucous membrane of the trachea as well as the lung organs of the human body, and thus the symptom of lung pain occurs. When the human body gradually adjusts the breathing frequency of running, strengthens the coordination and cooperation between breathing and pace, and breathes and exhales evenly, it can ensure that the oxygen is fully exchanged in the lungs, and at the same time, it can also weaken the friction between the gas and the respiratory tract, so that the symptom of lung pain will be relieved and gradually disappear. If the symptoms of lung pain occur when running, it is recommended to run appropriately according to their own conditions and pay attention to rest, if the symptoms of lung pain occur for a long time, it is recommended to go to the hospital in time to carry out relevant examinations, so as to avoid delaying the condition.
