The Seven Simple Rules of Life, or 7 heart-healthy lifestyles, include: 1. Regular exercise: aerobic exercise for 30 to 40 minutes 3 to 5 times a week is good for your health. Brisk walking and jogging are recommended ways to exercise. The right amount of exercise means a certain amount of intensity and a little sweat. 2, ideal blood lipids: in general, for people without cardiovascular disease risk factors, the total cholesterol level should be controlled below 200 mg/dl and the low-density lipoprotein cholesterol (LDL-C) level should be controlled below 130 mg/dl. However, the “ideal” cholesterol levels vary according to the risk factors, and intervention is required under the guidance of a physician. 3.Healthy diet: balanced and reasonable diet, mainly low cholesterol, low fat, low sugar, low salt, more vegetables and fruits, etc. 4, ideal blood pressure: the ideal blood pressure level for normal people is 120/80 mmHg, and the blood pressure of hypertensive patients should be long-term and smoothly controlled at 140/90 mmHg or less. 5, appropriate weight: body mass index (BMI) control below 25 will greatly reduce the risk of cardiovascular disease and metabolic syndrome. The calculation is weight (kg)/height (m)2. 6, ideal blood sugar: fasting blood sugar level should be less than 6.1 mmol/L (110 mg/dl) and glycosylated hemoglobin (HbA1c) level controlled at 6.2% or less. 7, do not smoke: smoking is the first preventable factor in the cause of premature death, and quitting smoking is the key to preventing cardiovascular disease. Sounds old-fashioned? But it also really works. The study found that each of these seven cardiovascular health assessments was associated with a reduced risk of heart failure, myocardial infarction and stroke later in life.
