Exercise-induced bronchoconstriction (EIB) occurs when the airways narrow as a result of exercise. This condition has been referred to as exercise-induced asthma (EIA); however, this term is no longer preferred. [1] While exercise does not cause asthma, it is frequently an asthma trigger. [1]
Asthma triggers are factors or stimuli that provoke the exacerbation of asthma symptoms or increase the degree of airflow disruption, which can lead to an asthma attack. [1] An asthma attack is characterized by an obstruction of the airway , hypersecretion of mucus and bronchoconstriction due to the contraction of smooth muscles around the ...
Exercise can trigger bronchoconstriction both in people with or without asthma. [116] It occurs in most people with asthma and up to 20% of people without asthma. [116] Exercise-induced bronchoconstriction is common in professional athletes. The highest rates are among cyclists (up to 45%), swimmers, and cross-country skiers. [117]
Respiratory adaptation begins almost immediately after the initiation of the physical stress associated with exercise. This triggers signals from the motor cortex that stimulate the respiratory center of the brain stem, in conjunction with feedback from the proprioreceptors in the muscles and joints of the active limbs.

There is growing evidence that psychological stress is a trigger. It can modulate the immune system, causing an increased inflammatory response to allergens and pollutants. [23] Cold weather can make it harder for patients to breathe. [24] Whether high altitude helps or worsens asthma is debatable and may vary from person to person. [25]
Other triggers include mechanical ventilation, sepsis, pneumonia, Gilchrist's disease, drowning, circulatory shock, aspiration, trauma—especially pulmonary contusion—major surgery, massive blood transfusions, [46] smoke inhalation, drug reaction or overdose, fat emboli and reperfusion pulmonary edema after lung transplantation or pulmonary ...
[1] [2] Risk factors include psychological stress. [2] The pain is not due to the heart. Diagnosis is based on the symptoms. Other conditions that may produce similar symptoms include angina, pericarditis, pleurisy, and chest trauma. [1] Treatment is usually via reassurance, as the pain generally resolves without any specific treatment.
Occupational asthma is new onset asthma or the recurrence of previously quiescent asthma directly caused by exposure to an agent at workplace. It is an occupational lung disease and a type of work-related asthma. Agents that can induce occupational asthma can be grouped into sensitizers and irritants. [1]
