What diseases should we be careful to guard against in heavy snow and solar terms?

The sudden drop in temperature during the solar term of heavy snow has a very significant impact on the human body: blood pressure, trachea, stomach and other aspects have changed because of the cold weather. At this time, it is necessary to prevent stroke, heart disease and digestive tract ulcer.

First, prevent stroke.

For people with poor vascular elasticity, the sudden change of temperature will bring about blood pressure fluctuation and trigger a stroke. Cold will excite people's sympathetic nerves, increase catecholamine in blood, and lead to systemic vasoconstriction. At the same time, when the temperature is low, the perspiration decreases and the blood volume increases relatively, which can increase blood pressure and promote cerebral hemorrhage. Therefore, first of all, we should pay attention to the treatment of primary diseases such as hypertension, coronary heart disease, diabetes and arteriosclerosis, and secondly, we should pay attention to finding the precursors of stroke, such as sudden dizziness, severe headache, blurred vision and numbness of limbs.

Second, prevent heart disease.

Include angina pectoris and myocardial infarction. Winter solstice and late winter and early spring are the two peak periods of acute myocardial infarction. The reason is not only that low temperature stimulates human sympathetic nerve and causes vasoconstriction, but also that cold can increase fibrinogen content in blood and blood viscosity, which is easy to cause thrombosis and block coronary blood vessels. In addition, the diseased coronary artery is particularly sensitive to cold stimulation, which contracts and even occludes blood vessels, leading to myocardial ischemia and hypoxia, angina pectoris and even myocardial infarction. Therefore, the elderly should pay attention to cold and warmth, add clothes and bedding at any time according to the weather changes, and conduct regular physical examination of the cardiovascular system to prevent the invasion of cold. Under the guidance of a doctor, drugs for thrombolysis, lipid lowering, vasodilation and myocardial ischemia and hypoxia should be selected.

Third, prevent digestive tract ulcers.

At this time, due to the increased excitability of the human nervous system stimulated by cold, the autonomic nerves that dominate the internal organs are in a state of tension. Under the reflex action of parasympathetic nerve, gastrointestinal lymph nodes are dysfunctional, and gastric acid secretion increases, which in turn stimulates gastric mucosa or ulcer surface, causing spasmodic contraction of the stomach, causing ischemia and hypoxia of the stomach itself, thus causing recurrence of gastric diseases. Therefore, we should pay attention to the warmth of the stomach and diet conditioning. The daily diet should be light and easy to digest, so as to eat less and eat more regularly, avoid raw food, and quit smoking and drinking.
