? For example, coronary heart disease, as we all know, is that the artery that supplies blood to the heart (medically called coronary artery) is blocked. When the blockage reaches about 70%, we will feel uncomfortable, and there will be symptoms such as palpitation, shortness of breath and chest tightness. We went to the hospital, had a check-up, and found that the arterial blood vessels had been blocked to about 70%. The doctor wrote in the diagnosis: coronary heart disease. So our blood vessels are blocked to 70% at once? The answer is clear, no, it will take more than ten years to block the coronary artery to 70%. That blood vessel may be blocked at a few years old. Do you feel the traffic jam when it reaches 40%? No, at most, when you are angry or do heavy work, you will easily feel chest tightness and fatigue. Can you say that if the blood vessels are blocked to 40%, you will be fine? No, because blood vessels are not blocked at all when they are born, so the state where blood vessels are not blocked at all and blocked to 70% is what we often call "sub-health".
The essence of sub-health tells us that our body is in a stage of being sick and insensitive for a long time. Therefore, we should pay attention to adjusting our lifestyle when we are sub-healthy, and vice versa.
