Strokes are rapid and serious, with many sequelae. In fact, stroke can be effectively prevented by controlling it from the source in five simple steps. Eat a reasonable diet Limit salt intake (<8g/day), cholesterol intake should be <300mg per day; eat more vegetables, fruits, cereals, milk, fish, beans, poultry and lean meat, etc. to balance energy intake and needs. Studies have shown that people who eat more fruits and vegetables every day can reduce the risk of stroke by about 31%. Avoid obesity Studies have found that being overweight increases the risk of stroke by 3-5 times. Conversely, for every kilogram of body weight lost, the risk of stroke is reduced by 30 percent. The body mass index (BMI) target is 18.5 - 24.0 kg/m2. BMI is calculated as weight (kg)/height (m2), and if the resulting value exceeds 26, weight loss is needed. Moderate exercise Exercise can enhance heart function, improve blood vessel elasticity, promote blood circulation throughout the body, and increase blood flow to the brain. It is appropriate to maintain 30-60 minutes of exercise every day, which can effectively lower blood pressure, consume calories and maintain body weight. A moderate increase in physical activity and not over-exercising can reduce the risk of stroke onset. Tai chi and brisk walking are both suitable exercise methods for middle-aged and elderly people. The ideal brisk walking speed is 1km/10min. Say no to smoking and alcohol! Smoking (including second-hand smoke) and alcohol abuse are two important risk factors for stroke. Smoking causes irreversible damage to the blood vessel wall and leads to or aggravates atherosclerosis; although moderate drinking is good for improving systemic circulation and produces neuroprotective effects after a vascular accident, perennial alcohol abuse can lead to a rise in blood pressure after drinking or delayed. Stroke screening checkups People over 40 years old who are at high risk of stroke are expected to receive a stroke screening checkup every 1-2 years and receive scientific stroke prevention advice. If you experience sudden numbness or weakness in one arm, leg or face, sudden loss of speech, sudden visual impairment (blackness or distortion) or double vision, sudden difficulty walking, dizziness, unstable walking or choking on water, sudden onset of severe headache of unknown origin, you should be alert to the precursor of stroke and go to a hospital with stroke treatment facilities for stroke screening and treatment as soon as possible. It is important to go to a hospital with stroke care facilities for stroke screening and treatment as soon as possible to avoid adverse consequences.
