Abstract: Autumn and winter cold season is a “hurdle” for patients with high blood pressure, every autumn and winter when the temperature is relatively low, some patients with high blood pressure began to feel annoyed, because the previous well-controlled blood pressure, as soon as the cold weather began to “mood”. The “elevated” phenomenon occurs. Why does blood pressure like to be “moody” in cold weather? This is because, when the weather becomes cold, the sympathetic nerve excitement, adrenal cortical hormone secretion increases, which makes the blood vessels constrict, peripheral resistance increases, which in turn leads to an increase in human blood pressure, and the ability of the elderly to adapt to the cold and the ability to regulate blood pressure is slightly less, so the blood pressure fluctuations will be more obvious, which makes the original quite effective antihypertensive drugs in the cold weather become unable to hold. This makes the originally effective antihypertensive drugs become untenable in cold weather. If this does not adjust the medication in time, blood pressure continues to rise, patients may experience varying degrees of dizziness, chest tightness and other uncomfortable symptoms, and blood pressure can reach dangerous values and even cerebral hemorrhage, ischemic stroke and myocardial infarction, seriously threatening health and even life. How to get through the cold season with high blood pressure The autumn season is a transitional stage in which the yang energy gradually disappears and the yin energy gradually grows, and the climate changes from hot to cold. The “Su Wen – Four Qi Tuning Shen Da Lun” says “In March, this is the month of autumn, the weather is calm, the weather is urgent, the earth is clear. Sleep early and get up early, with the chicken. Make the will peaceful, in order to slow down the autumn punishment, astringent Shen Qi, so that the autumn gas flat, no outside its will, so that the lung gas clear. This autumn qi should be, the way to nourish the harvest.” It is pointed out that the autumn qi is strong, everything in nature is clear, the metabolism of the human body is in decline, and the spiritual qi is inwardly stored, so it is advisable to follow the autumn qi and maintain the astringent function of the human body. Adjusting work and rest Since ancient times, there is the saying “day to nourish Yang, night to nourish Yin”, good sleep can ensure that the internal organs get sufficient recuperation. After autumn, the work and rest should be gradually adjusted to the state of “early to bed and early to rise”, early to get the nourishment of the natural morning dew, which is conducive to the body to adapt to the autumn “dryness”, early to bed can nourish the body’s Yin essence, in order to achieve the effect of nourishing Yin and moistening dryness. Pay attention to warmth Pay close attention to weather changes, cold stimulates vasoconstriction, easy to cause blood pressure to rise. Increase and decrease clothing at the right time, and minimize unnecessary going out in cold and windy weather, but if you need to go out, you should also do a good job of keeping warm. Reasonable exercise Reasonable exercise is good for blood pressure control and reduce complications, therefore, patients with hypertension can choose suitable exercises according to their own situation, such as walking, tai chi, etc. In addition, patients with hypertension who have the habit of morning exercise can choose to exercise outdoors during sunny and warm hours. Pay attention to diet In the colder seasons of autumn and winter, people often say that they need to nourish fat to protect themselves from the cold. As a patient with hypertension, appropriate tonic is certainly needed, but the diet should also pay attention to maintaining a reasonable dietary structure, low fat, low salt, low cholesterol and high potassium, high calcium, high fiber diet, do not eat too greasy food, and eat more fresh vegetables and fruits. This negative emotion will affect the endocrine regulation and make blood pressure fluctuate. Therefore, patients with hypertension in autumn and winter should adjust their mindset, maintain a happy and calm mood, and reduce or avoid negative emotions. Monitoring blood pressure Blood pressure is a dynamic value that can fluctuate due to many factors. Therefore, patients with hypertension should frequently test their blood pressure, keep records, and observe the changes in their blood pressure. Some people hear other hypertensive patients say that the cold weather antihypertensive drugs should be fine-tuned, so they do not care whether their blood pressure has increased, they have to increase their own medication, in fact, this is also unscientific. Many patients lack professional medical knowledge and are unfamiliar with the medicinal properties, so if they adjust their medication at will, they will not only fail to achieve the desired antihypertensive effect, but may damage their vital organs due to the excessive effect of the medication.
