What is the connection between cold weather and high heart pressure? Do you know that?/You know what? Do you know that?/You know what?

In cold weather, in order to provide enough energy for the body, the heart rate will be accelerated, and the oxygen consumption and workload of the heart will also increase. At low temperature, the blood is thick and the circulation speed is slow, which further increases the burden on the heart. Once stimulated by cold, coronary artery tends to contract and spasm, and blood pressure rises. Patients with original cardiovascular diseases may have acute myocardial ischemia, induce angina pectoris and even myocardial infarction.

When breathing is short and cold, especially in the north, walking against the wind sometimes leads to dyspnea, cough and nausea. This is because cold and dry air will dry the nose, stimulate the throat, contract the small trachea and produce respiratory stress reaction. Therefore, when going out in winter, we should protect our oropharynx and try to breathe through our nose to avoid dry mouth and the invasion of cold air. Usually pay attention to hydration, not less than seven or eight cups a day, honey water has the effect of moistening dryness; Eat more lungs-moistening foods such as pears, tremella and lilies; You can use a humidifier at home to keep the humidity constant.

When the joints are stiff and cold, many people will feel muscle pain, joint stiffness and arthritis pain. That's because too low temperature will lead to muscle contraction, reduced blood supply and synovial fluid secretion, and poor compliance of tissues around joints (including muscles and ligaments). Therefore, when the temperature drops suddenly, you must add clothes to keep warm in time and avoid staying outdoors for a long time. Climbing mountains and stairs will increase joint load, so try not to do it in winter. Be sure to warm up before exercise to avoid stiff limbs and injuries after strenuous exercise.

Pay attention to cold prevention measures. The reason why cardiovascular events occur in winter is mainly because the temperature difference between indoor and outdoor is too large, especially in places with heating in the north, and the indoor and outdoor temperatures may differ by 20 or 30 degrees. So be sure to keep warm, because most heart diseases occur below 10 degrees. When we go out, we must wear thick cold-proof clothes to keep warm.

Don't exercise just because it's too cold. You should know that if the weather is cold and you are in poor health, it is easy to catch a cold. A cold leads to respiratory tract infection and is very easy to induce viral myocarditis. If it is serious, it will lead to myocardial infarction or sudden death. So be sure to prevent colds and try not to go to crowded places to avoid being infected by others. We should also do more exercise to ensure adequate nutrition and sleep. If you catch a cold unfortunately, don't delay, you must actively treat it.
