Why do you feel chest tightness and shortness of breath in hot weather?

Feeling chest tightness, shortness of breath and dyspnea in hot weather may be caused by heatstroke, lack of oxygen, cardiac insufficiency and obvious relaxation of cerebral vessels. Details are as follows:

1, heatstroke

Heatstroke is caused by the loss of water and electrolyte in high temperature environment, the problem of cooling system and the accumulation of heat in the body. Among them, threatened heatstroke will have nervous system manifestations, which can be manifested as dizziness, headache and other symptoms. It is suggested to leave the hot environment in time, reach the shade and drink plenty of water.

2. Hypoxia

In hot weather, the body temperature rises, leading to shortness of breath. Shortness of breath easily leads to incomplete alveolar gas exchange, so that when the oxygen saturation is insufficient, the oxygen partial pressure is low and the carbon dioxide partial pressure is high, and the proportion of ventilation blood flow is unbalanced. The human body feels chest tightness and shortness of breath.

3. Incomplete mental faculties

Diseases such as coronary heart disease and cardiomyopathy can lead to cardiac insufficiency, shortness of breath, palpitation, palpitation, edema of both lower limbs and other symptoms.

4. The cerebral vascular dilatation is obvious.

When the weather is hot, the cerebral vessels dilate obviously, and the blood flow in the head slows down, resulting in insufficient blood supply and dizziness. Some drugs that can improve microcirculation and dilate blood vessels can be taken orally, such as Xueshuantong capsule, Xueshuantong capsule and Xueshuantong capsule. If it is accompanied by elevated blood lipids, hypolipidemic treatment is needed.

Symptoms of chest tightness and shortness of breath in hot weather may be related to physical weakness, heart disease and bradycardia. It may be due to the change of temperature and air pressure, which leads to vasospasm and cardiac contraction, resulting in insufficient blood supply to the heart. Attention should be paid to keeping the indoor air fresh, with proper temperature and humidity and good ventilation. You can take compound Danshen dripping pills, Xinbao capsules and other drugs. Eat more seasonal fruits and fresh vegetables, and before treatment, you can also do ECG, color Doppler ultrasound, myocardial enzyme spectrum and other tests to determine the cause.
