Cerebral hemorrhage is also closely related to the change of weather. When the weather becomes cold, the vascular bed of human skin contracts, resulting in a dramatic increase in the amount of blood circulating in the heart and brain, increasing the load on the heart and resistance to cerebral circulation, which can easily cause an increase in blood pressure. Therefore, winter is a high incidence period for cerebrovascular accidents. Elderly people suffering from hypertension, cardiovascular and cerebrovascular diseases and other chronic diseases should be especially vigilant in winter to prevent cerebrovascular accidents. First, life should be regular: the elderly can properly do some labor within their reach, but not too strenuous. Second, control hypertension: to ideally control blood pressure must pay attention to many aspects: (1) blood pressure control in the ideal level: a large number of people in China’s intervention experiments show that: 140/80mmHg may be the ideal blood pressure value to prevent cerebrovascular disease, but some people’s blood pressure lowered to that level instead of the symptoms of cerebral ischemia, the reason may be due to the speed of lowering the pressure too fast, but also may be for these people The ideal blood pressure for these individuals is slightly higher than these values. This is due to individual differences, and a more feasible approach is to gradually lower the blood pressure to the above level or slightly higher over a period of time without the uncomfortable symptoms of cerebral ischemia. (2) Blood pressure should be controlled smoothly: make the “peaks” and “troughs” of blood pressure close to each other within 24 hours. This can avoid the damage of blood pressure fluctuation to the blood vessel wall, and can prevent the low blood pressure may lead to insufficient cerebral perfusion, do not lower the blood pressure too fast. (3) maintain a comfortable mood: the occurrence of primary hypertension and the environment and mental state have a clear relationship. Environmental factors include diet, social environment, life changes, and mental conflicts. Highly stressful events can cause sympathetic-mediated vasoconstriction and other autonomic responses, which have a large and long-lasting effect on blood pressure. brod observed: hypertensive patients have a longer-lasting vasoconstriction response than normal people during stress, and susceptible individuals show an acute and long-lasting increase in blood pressure in response to general and specific stress. Psychophysiological studies suggest that mental stress, autonomic activity and conditioning can cause hypertension. Therefore, supportive psychotherapy for hypertensive patients is essential. (4) At the same time, non-pharmacological therapy: such as limiting salt intake, reducing weight, lowering blood lipids, moderate exercise, biofeedback therapy, etc., can consolidate and promote the antihypertensive effect of drugs. Third, maintain a good state of mind: maintain an optimistic mood and avoid getting too excited. Be calm, reduce worries, do not be overly sad and happy, be indifferent to fame and fortune, and be happy with what you have. Fourth, pay attention to diet: diet should pay attention to low salt, low fat, low sugar, eat less animal brain, offal, eat more vegetables, fruits, soy products, with the right amount of lean meat, fish, eggs. Five, the prevention of constipation: constipation, defecation force, not only the abdominal pressure rises, blood pressure and intracranial pressure also rises at the same time, it is easy to make the fragile small blood vessels rupture and cause cerebral hemorrhage. To prevent constipation, eat more fiber-rich foods: such as green vegetables, celery, leeks and fruits, appropriate exercise and morning before waking up abdominal self-care massage, or with appropriate drugs such as marijuana pill, honey orally, open cork, glycerin topical, can effectively prevent constipation. Sixth, prevent strain: physical and mental labor should not be overworked, overload work can trigger cerebral hemorrhage. Seven, pay attention to weather changes: cold weather is a good season for stroke, vasoconstriction, blood pressure is prone to rise. Pay attention to keep warm so that the body adapts to climate change. Also according to their health status, some suitable physical exercise: such as walking, doing radio gymnastics, etc., to promote blood circulation. Eight, often move the left hand: in daily life, try to use the left upper limb and left lower limb, especially the left hand, can reduce the burden on the left hemisphere of the brain, but also exercise the right hemisphere of the brain, in order to strengthen the coordination function of the right hemisphere of the brain. Medical research shows that: cerebral hemorrhage is most likely to occur in the right hemisphere where the blood vessels are more fragile, so the best way to prevent the occurrence of cerebral hemorrhage is to use the left hand to turn two fitness balls in the morning and evening to help enhance the coordination function of the right hemisphere. Nine, pay close attention to changes in their own body: stroke will have some aura symptoms, such as unprovoked severe headache, dizziness, syncope, some sudden body numbness, weakness or transient blindness, language communication difficulties, etc., should be timely medical care, examination and treatment.
