Patients with hypertension are most at risk in summer. Do you know why?
Summer is the most dangerous, because the weather temperature in summer is generally high, and patients with hypertension usually have poor adaptability to environmental temperature. If the temperature is higher, it may easily lead to stroke, increase blood viscosity, and may also form thrombosis, so the wind risk in summer is more serious than in winter.
Hypertension is different from ordinary people, and blood pressure may be greatly affected by the environment. In some hot seasons, because the weather is particularly hot, there may be a sudden increase in blood pressure, which may easily lead to the risk of cerebral hemorrhage or cerebral infarction. Usually the temperature is high, sweating is more, leading to blood concentration, blood vessels are easy to block, causing cerebral infarction.
What is hypertension? What is hypertension? This is the definition of hypertension. Hypertension first refers to the blood of systemic circulation, that is, the blood pressure of arms and legs that we can measure in the periphery, not the blood pressure of pulmonary circulation and pulmonary artery, and the blood of main systemic circulation. By measuring the blood pressure of upper and lower limbs, systemic blood pressure rises, and the standard for rising is generally three times. If the blood pressure is higher than normal on different days, it is determined as hypertension. Then you may need this sphygmomanometer for three times or 20 times.
So what is this high blood pressure value? The previous standard was 140/90mmHg or above, that is, systolic blood pressure 140 or above and diastolic blood pressure above 90. Therefore, the standards in Europe and America, especially the United States, may be stricter in recent years, and hypertension can be considered above 130/80mmHg. This is a numerical value. Then blood pressure rises, accompanied by functional or organic damage to many organs such as heart, brain and kidney, including eyes. Such a syndrome is hypertension, which was originally considered as a disease, but now it will be considered as a clinical syndrome. The so-called syndrome is a variety of manifestations, the cause is unknown. It is not a single disease, but a combination of various clinical manifestations. This is a definition of hypertension at present.
