For patients with hypertension winter is an important juncture where a little carelessness can endanger health or even life. Medication to lower blood pressure is the basic treatment, while nearly 70% of patients have not undergone regular treatment. How to choose and take medication is also a big problem for patients. According to the proposal of everyone brief science. A, winter blood pressure will be high, timely adjustment is the right way People’s blood pressure 24 hours a day is changing, of course, with the seasonal changes, many patients in the summer blood pressure is easy to control, or even low, but once the winter blood pressure will be significantly higher, even after increasing the drug is still difficult to control. The reason why blood pressure rises in winter is the body’s response to changes in the surrounding environment. The cold in winter causes blood vessels to constrict, which, combined with less exercise and less sodium perspiration, can cause blood pressure to rise significantly. Excessive elevation of blood pressure will make the incidence of myocardial infarction, heart failure, cerebral thrombosis, cerebral hemorrhage will greatly increase. The serious consequences of these diseases are increased mortality and disability rates. Second, blood pressure must always monitor, adjust the program in a timely manner When winter arrives, in order to prevent serious complications of hypertension such as cerebral hemorrhage, special attention should be paid to the monitoring of blood pressure. For patients whose blood pressure is still unstable should monitor blood pressure changes every day, especially pay attention to observe the blood pressure in the morning before taking medication and at night before going to bed, if the blood pressure is unstable should promptly consult a doctor and adjust drug therapy. Many patients can easily control their blood pressure by taking a little medicine in summer, and their blood pressure can even be on the low side. Therefore, when the seasons change, we should pay more attention to monitor the changes in blood pressure, adjust the medication at the right time, and patients who used to take a drug may have to increase the dose or take two drugs. In short, blood pressure changes should be detected in time, high blood pressure timely adjustment of drugs, as far as possible to reduce the cardiovascular and cerebrovascular hazards. You can also go to the hospital to do a 24-hour ambulatory blood pressure monitoring, for patients with large fluctuations in blood pressure can help more reasonable adjustment of drugs. Third, patients should beware of the morning exercise, avoid the morning peak to keep safe Human blood pressure is 24-hour fluctuations, which is a normal physiological phenomenon. People’s blood pressure is lower at night when they sleep, and is lowest at about 2-3 am. Blood pressure rises rapidly in the early morning before waking up and reaches or approaches its peak in the first few hours of activity after waking up in the morning (about 6-9 am). The blood pressure at this time is even higher than at night by more than 40-50 mmHg, a phenomenon medically known as the “morning peak” of blood pressure. This is a dangerous time for patients with hypertension and cardiovascular diseases because the patient’s sympathetic nerves are in a period of excitement, the heart rate increases and blood pressure rises; in addition, the patient has not drunk water overnight and exhales a lot of water through breathing, which increases blood viscosity. For patients with atheromatous plaque, the plaque will easily rupture at this time, leading to myocardial infarction, cerebral infarction and cerebral hemorrhage. Therefore, we do not advocate morning exercise for patients with hypertension whose blood pressure is not under control, and we can exercise in the morning after the blood pressure is relatively stable. Fourth, a reasonable diet is the key, away from the three high more green vegetables hypertensive patients in winter daily life, should also pay attention to the following points: (1) a reasonable diet, away from the three high food. A large number of three high (high salt, high sugar, high fat) food intake, aggravating atherosclerosis. Therefore, we should limit the intake of three-high foods and eat more grains and cereals. (2) Drink more water appropriately, drink more porridge or soup at home (be careful not to be too salty), and eat more fruits and vegetables. (3) Maintain a reasonable temperature difference between indoors and outdoors. Patients with hypertension have poor adaptability to temperature and regulation of blood pressure, and blood pressure is prone to fluctuations. Therefore, it is advisable to keep the indoor temperature around 20-25℃, ventilate frequently, and try to reduce going out when it is suddenly cold and windy. (4) If the patient’s face or extremities suddenly feel numb, weakness, difficulty in speaking, or suddenly have vertigo, headache, and from intermittent to persistent, or accompanied by nausea and vomiting, these are the early signs of cerebral hemorrhage or cerebral thrombosis, at this time, the patient should be kept quiet, lying down, and call 10 emergency as soon as possible. (5) Try not to move the patient during the acute period just after the onset of the disease, otherwise the condition may be aggravated. Be sure to keep the phone open and send someone to guide the arrival of ambulance personnel at a clearly marked location.
