People who exercise for a long time are also prone to brain infarction because there are many reasons for the formation of brain infarction. Patients who regularly participate in physical exercise can reduce the incidence of brain infarction, but it does not mean that if they exercise regularly, patients will not suffer from brain infarction. There are many risk factors that lead to brain infarction. Uncontrollable factors, such as genetic factors, environmental factors, and aging are the risk factors that lead to atherosclerosis of the brain and are the risk factors for the formation of brain infarction. Controllable factors, such as hypertension, diabetes, hyperlipidemia, hyperhomocysteinemia, the above diseases can also lead to cerebral atherosclerosis and cause brain infarction in patients, but the above risk factors can be controlled. Patients’ poor lifestyles, such as sedentary lifestyle, smoking and alcohol consumption may aggravate patients’ atherosclerosis, so patients should also pay attention to circumvent them.
