1. The main evidence that high sodium salt diets are associated with hypertension comes from population-to-population comparative studies. Restricting sodium intake (salt and sodium-containing foods) in hypertensive patients decreases blood pressure, and taking diuretics, excreting sodium and water, and blood pressure also decreases. In some people with low sodium intake, no cases of hypertension are known at all, while the per capita sodium intake in Japan is about 2-4 times that of Americans, and almost one-third of the population suffers from hypertension. According to our survey, the average salt intake of Heilongjiang residents is 17-17g/d, which is significantly higher than the physiological needs and the national average, and the incidence of hypertension is higher than the national average. 2. Tension stimulation, tension stimulation is a series of activities caused by internal and external tension stimulating factors with obvious subjective urgency, corresponding nervous behavior and accompanying physiological and psychological changes. Tension stimulation has a significant effect on improving the excitability of the brain stem reticular ascending activation system, causing a series of blood catecholamine hormones to rise, blood pressure to rise, heart rate to speed, increase blood supply to the head and muscles, and reduce blood supply to the viscera. If this period is too intense and persistent or repeated, it can lead to functional and organic damage to the cardiovascular system.
3. Overweight and obesity, overweight and obesity caused by weight gain is a primary independent risk factor for hypertension, coronary heart disease and ischemic stroke. 4. Alcohol consumption, nearly 30 studies in Europe, America and other countries have found that excessive alcohol consumption (daily alcohol intake greater than or equal to 35g) can increase the prevalence of hypertension, control alcohol intake, blood pressure levels decreased significantly. 5. Smoking, smoking can make blood pressure rise sharply in the short term. Studies show that patients with hypertension can greatly reduce the risk of cardiovascular disease after quitting smoking. 6. Lack of exercise, regular physical activity is not limited to reducing the risk of the heart. Regular exercise can relieve mental tension, enhance physical fitness and improve heart function. 7. Genetic factors. In recent years, many studies have shown that hypertension is a variety of genetic diseases. The occurrence of this disease is affected by genetic factors and is related to environmental factors.
