Chest tightness and shortness of breath in summer may be a physiological reaction, but also may be related to respiratory diseases and heart diseases.
1. Physiological reaction: in summer, the temperature is high, if long time in the air circulation or stuffy place, may be due to a brief lack of oxygen and chest tightness, shortness of breath and other discomforts.
2. Disease factors:
(1) Respiratory diseases: such as bronchial asthma, when exposed to certain summer pollen, it may induce airway spasm, resulting in chest tightness and shortness of breath; also, for example, emphysema, the stuffy environment in the summer further reduces the ventilation function of the lungs, which leads to chest tightness and shortness of breath in patients.
(2) heart disease: such as coronary heart disease, coronary artery stenosis or occlusion, myocardial blood supply is insufficient, resulting in chest tightness, shortness of breath, and summer temperatures can make myocardial ischemia increased risk of seizures; but also for example, heart failure, the heart pumping function is impeded, resulting in pulmonary stagnation, which causes chest tightness, shortness of breath, and high temperatures in the sympathetic nerve excitation in the summer, heart failure symptoms can be exacerbated.
Summer chest tightness and shortness of breath, it is recommended to rest in the air circulation, moderate amount of water, if there is no significant relief, should promptly consult a doctor.
