Is a foggy winter night suitable for walking in the park?

First, the amount of pollutants inhaled by exercise in smog increases, which harms vascular endothelium. Droplets contain a lot of harmful and toxic substances, such as various acids, alkalis, amines, phenols, benzene, dust, pathogenic microorganisms and foreign proteins. When pollutants enter human blood with breathing, they will cause slow and sustained damage to vascular endothelium, promote the occurrence of atherosclerotic plaques, affect the blood supply to the heart and brain, cause chest tightness, shortness of breath, palpitation, dizziness and other symptoms, and even lead to the recurrence or deterioration of the original cardiovascular and cerebrovascular diseases.

Second, the humid and cold smog gas can stimulate vasospasm. When the wet and cold fog is suddenly inhaled into the warm human body, the blood vessels in the body can't adapt to the sudden low-temperature stimulation, and it is easy to have vasospasm. Vasospasm will narrow the vascular lumen and hinder the passage of blood. On the other hand, it can also cause plaque rupture in patients with plaque in blood vessels, forming thrombus to block blood vessels and completely cut off blood supply to the heart and brain.

Third, low pressure in foggy days causes cardiovascular and cerebrovascular diseases. On the one hand, the low-pressure climate in smoggy days will also promote the formation of atherosclerotic plaques, thus inducing and aggravating cardiovascular and cerebrovascular diseases. On the other hand, it will also affect people's psychology, make people feel depressed and depressed, cause symptoms such as high blood pressure, rapid heartbeat and shortness of breath, and cause damage to heart and brain health.

So doing housework at home is also exercise. I wish you the best of health!
