Hypertension is an important risk factor for the development of cardiovascular diseases. It has now become a killer that affects people’s health. Since hypertensive patients mostly do not take hospitalization, they usually still insist on their normal life and work. Therefore, the self-care and rehabilitation of such patients is very important, to learn to take care of and control themselves. 1, reduce mental stress to maintain mental balance The prevalence of long-term stress, such as drivers, pilots, doctors, accountants, etc., is significantly higher, long-term mental tension, anxiety, depression, subcortical nerve dysfunction, increased sympathetic excitability, small blood vessel constriction, increased cardiac output, resulting in increased blood pressure. The effect of emotional changes on blood pressure is obvious, especially in hypertensive patients, where sudden changes in emotions leading to cardiovascular events are common. Therefore, hypertensive patients must first maintain their own psychological balance, correctly understand the causes of the disease, drug treatment, their own health care situation, reduce mental stress, eliminate fear, pessimism and impatience and other adverse emotions. Secondly, in work and life, to establish a harmonious family and good interpersonal relationships, deal with things magnanimously, correctly treat fame and fortune, so that they are in a calm, comfortable, relaxed, optimistic and good state of mind, to maintain normal and stable blood pressure. 2, quit smoking and limit alcohol Smoking can increase the risk of hypertensive complications such as stroke, myocardial infarction and sudden death, can reduce or offset the efficacy of antihypertensive treatment, aggravate lipid metabolism disorders, reduce insulin sensitivity, and increase the tendency of cardiac hypertrophy. Long-term alcohol consumption can lead to vasculopathy, which is harmful but not beneficial. Quit drinking or reduce the amount of alcohol consumption, can make a significant reduction in blood pressure, after drinking alcohol pressurization reaction and body thin people should quit drinking. 3, moderate exercise to reduce weight The occurrence of hypertension and obesity is indeed closely related. Some data show that reduce weight 10% systolic blood pressure can be reduced by 6.6mmHg. and help improve the accompanying risk factors, such as diabetes, hyperlipidemia, insulin resistance, and indirectly reduce salt sensitivity, very beneficial to the control of blood pressure. Weight loss in addition to diet moderation, a moderate increase in activity is very important. Patients with mild to moderate hypertension can be trained in aerobic metabolism, such as walking, jogging, cycling, swimming and dancing. Depending on the individual, elderly people and patients with grade 3 hypertension can appropriately play tai chi and practice qigong to achieve the purpose of quieting the mind and nourishing the heart, regulating the qi and the middle. But pay attention to the intensity, the maximum heart rate should not exceed 150 times / min, each time to 30 to 60 minutes is appropriate. 4, reasonable diet Diet is an important part of the non-pharmaceutical treatment of hypertension, but also an important part of self-care. Some people propose the principle of “four low, three supplements, one control”. Four low refers to low sodium, low fat, low cholesterol, low calories; three supplement refers to potassium, calcium, magnesium; control sugar food. Daily sodium chloride should be less than 6 grams. Rich in potassium are bananas, oranges, rape, shiitake mushrooms, dates, etc. Eat more coarse grains, fish, soy products, milk, moderate amount of lean meat. 5, active prevention and control of diabetes hypertension and diabetes often coexist, will significantly increase the morbidity and mortality of cardiovascular disease. Patients with hypertension mostly have insulin resistance, which reduces insulin sensitivity and contributes to increased blood pressure, atherosclerosis and disorders of blood sugar metabolism. In general, blood pressure is required to be controlled below 140/90mmHg, while in hypertension combined with diabetes it is required to be controlled below 130/80mmHg.
