For example, I am not a very fat person, but I am in good health, with six abdominal muscles, strong chest muscles and two big biceps brachii. Anyway, I'm in good health and in great shape. Just not very fat. When both hands exert force, the "blue veins" bulge will appear, especially near the wrist, and the blood vessels and muscles are obviously separated. However, if this is unhealthy according to the topic, then my exercise for so many years will be in vain, so my personal experience of exercising for so many years tells me that this is a very healthy performance. If you judge people's health according to the description of "blue veins", how do you want Chinese and western medicine to live?

Give me an example.

A friend of mine is a relatively fat person. He usually exercises, but no matter how he exercises, he just can't lose weight. He does everything every day, such as running, lying on his back, stretching and dancing. , covered in sweat. Of course, there are also some effects, such as muscles. Although it is not obvious, it is enough to show that this person is healthy. When he was doing stretching exercise, he specially observed the blue veins on his hands, and there was no bulge. Although there are traces of muscle, there is no bulge.

Therefore, the blue veins on the hands are related to the fatness of a person's body and have nothing to do with health. According to common sense, if a person's hands exert force, it will inevitably lead to vasodilation, which will inevitably lead to excessive blood flow to his hands, leading to an increase in blood vessels and protruding the skin surface, which looks like a "blue vein" bulge.

Well, I hope the subject understands.
