Normal blood pressure (systolic blood pressure is 100- 120mmHg, diastolic blood pressure is 60-80mmHg, and blood pressure is high when it exceeds 140/90), which only covers most healthy adults in China, and the blood pressure values of a few people (diastolic blood pressure or systolic blood pressure or even both) are not in this normal range. However, if it is clear that they have no cardiovascular system-related diseases and corresponding discomfort symptoms, they are also healthy people, which means that your body has adapted to this blood pressure level and is suitable for you, so there is no need to worry or improve. For example, there is a range of the height of normal adults (check the specific figures by yourself), but Yao Ming's height is definitely beyond the standard, but he is not suitable for diseases such as gigantism. People are genetically superior. Can you call this a disease? (Excerpted from my answer to another question)
However, if your blood pressure is not at the same level as before, or you have some symptoms of fatigue, poor spirit and qi deficiency, it is abnormal.
