Why do I feel chest tightness and weakness when it’s hot?

In many areas of our country, the weather is relatively hot. Even in winter, you may only need to wear light clothes. When the weather is particularly hot, if you stay outdoors for a long time under direct sunlight and are surrounded by stuffy air, you will definitely get heatstroke, and in severe cases you may even die. What's more, many friends said that they always feel chest tightness and fatigue when the weather is hot. What is the reason?

1. Respiratory obstruction

If a tumor grows in the trachea or bronchi, the airway is narrowed, or the trachea is under external pressure (such as an enlarged thyroid gland), it will cause airway obstruction, difficulty breathing, and symptoms of chest tightness and shortness of breath.

2. Lung disease

The occurrence of lung diseases such as emphysema, bronchitis, asthma, atelectasis, pulmonary infarction, and pneumothorax can lead to enlarged alveoli, decreased elasticity, and impaired lung function, causing symptoms such as difficulty breathing and chest tightness.

3. Insufficient blood supply to the myocardium

Coronary artery sclerosis causes coronary artery stenosis. After the artery stenosis, the blood flow and the oxygen content in the blood decrease, and the heart is prone to ischemia and hypoxia, resulting in compensatory reactions such as chest tightness and shortness of breath.
