In winter, the human body enters the stage of recuperation, metabolism is relatively slow, hypertension patients enter a dangerous season. In addition, there is a folk saying “winter tonic”, in order to protect the cold, people will choose a lot of high-calorie high-fat things tonic, some of which are not easily digested and absorbed, but will affect blood sugar, blood lipids, uric acid, etc., aggravating the danger of hypertension. The idea that human blood pressure varies with temperature has been discussed for a long time. As early as 1921, Hopman et al. found that blood pressure increased during the cold season, and then Modesti et al. in Italy investigated 6404 consecutive cases of hypertensive patients attending outpatient clinics from October 1999 to December 2003 and found that the mean blood pressure was (141±12)/(95±8) mm Hg during the cold season and (136±19)/(80±7) mm Hg during the hot season. 19)/(80±7) mm Hg in the hot season, suggesting that blood pressure was significantly higher in the cold season than in the hot season. Subsequently, a series of research papers were published by domestic and international medical practitioners, most of which concluded that a drop in temperature during the cold season would lead to a certain degree of increase in blood pressure. The possible reasons for the rise in blood pressure in hypertensive patients due to the fall in winter temperature are: 1. The onset of winter causes the body to adapt to the cold weather and the sympathetic nervous system to become hyperactive and the renin-angiotensin-aldosterone system (RAAS) to activate, thus causing the small arteries in the body to contract, enhancing peripheral resistance and raising blood pressure; 2. 2, cold can increase the fibrinogen content of blood, blood viscosity and thus increase the risk of cardiovascular disease; 3, low temperature can make the body surface vascular elasticity is reduced, peripheral resistance increases, so that blood pressure increases. Therefore, we should be alert to the 4 alarm signals of cardiovascular patients in winter: 4 alarm signals in winter 1, whistling difficulties in winter, heart disease, whistling tract disease, may cause whistling difficulties, shortness of breath, shortness of breath, breath-holding, etc.. In particular, the phenomenon of suffocating awake, only sit up to whistle, may be heart failure, the need to seek early medical attention to check cardiopulmonary function. 2, palpitations Feeling irregular heartbeat, such as palpitations, rapid heartbeat, heartbeat missed a beat, etc., may have arrhythmia and other conditions, if the attack is frequent, you need to seek medical attention immediately. 3. Sudden pain Such as chest pain, shoulder pain, stomach pain, etc., may be ignored or confused as frozen shoulder or stomach disease. In fact, this may also be a precursor of heart attack. Doctors suggest that cardiovascular patients occur below the chin, above the navel sudden pain to be alert to heart problems. 4, dizziness, syncope Once the phenomenon of blurred consciousness occurs, it means that the brain blood supply, brain oxygen supply abnormalities, even if it is a transient attack, but if you do not take timely measures, the risk of stroke greatly increased. At the same time, we should reasonably adjust their own clothing, food and clothing: reasonable adjustment of food and drink, clothing and transport 1, first of all, moderate “eat” life diet should be regular, winter tonic must be based on personal constitution, the elderly should maintain a low-salt, low-fat diet, drink more water. According to the traditional habit of winter tonic, some frail elderly people suffering from hypertension often buy some tonic drugs to take. Chinese medicine believes that hypertensive patients must be targeted when taking tonic drugs. Patients with liver and kidney yin deficiency are advised to use yin tonics such as American ginseng, turtle plate, turtle shell, Cordyceps sinensis, Chinese wolfberry, and cow knee, or take turtle and turtle pills, which are beneficial for lowering blood pressure, relieving dizziness, dizziness, tinnitus and other symptoms, and enhancing physical fitness and promoting recovery. If hypertensive patients take ginseng, deer antler and other qi tonics with ascending and damp heat properties, it will not only be beneficial to lower blood pressure, but will aggravate the condition. Some patients with hypertension, even if they have a deficiency of qi, must also be based on the nourishment of yin, the use of calm medicinal tonic qi formulas for slow tonic, do not take strong tonic qi and yang products alone. In addition, if often feel chest tightness, dull, greasy moss does not dissolve hypertension patients, caution with tonic, preferably under the guidance of a doctor, first take the spleen and dampness and expectorant Chinese medicine to regulate, to wait for the above symptoms to ease or basically disappear, and then optional tonic. 2, followed by discretionary drinking In winter, many elderly people like to drink a glass of white wine to warm their bodies, in order to drive away the cold, do so with special caution. Drinking alcohol tends to make sympathetic excitement, enhanced metabolism, increased heart rate, causing an increase in blood pressure, which can easily lead to cerebrovascular rupture and stroke. Hypertensive patients should avoid drinking alcohol, especially should not drink more strong alcohol. Discourage hypertensive patients to drink alcohol, drinkers must limit the amount of alcohol consumed daily on the basis of good blood pressure control. Many people like to play mahjong, sedentary, coupled with the relative reduction in winter drinking water, blood viscosity increases, easy to form thrombosis. Therefore, to play less mahjong, drink more water and walk more. 3, again, pay attention to “wear” bedroom room temperature should generally be controlled at about 20 ℃ is appropriate, patients with cardiovascular and cerebrovascular disease in the outdoor temperature is too low to minimize going out, when going out should focus on the head and limbs to keep warm. The most afraid of a cold and a hot stimulus, so do a good job of keeping warm and avoid going from a cold place to a hot place at once. The mood should not be hot and cold, to avoid mood swings. 4, there is also a measure of “line” cardiovascular patients should be reasonable arrangements for exercise time and control the amount of exercise. In winter, wait for the sun to rise before going to exercise. It should be especially reminded that patients should not exercise in the morning. When you wake up in the morning, remember the three half minutes: don’t wake up immediately, lie in bed for half a minute; sit up for half a minute; sit on the edge of the bed with your legs down for another half minute.
