First of all, it should be clear that veins are not pathological tissues, but subcutaneous veins. Because the blood oxygen content in the vein is relatively low, it will appear blue in the light. Therefore, the blue veins are more obvious in people with whiter skin and thinner constitution. In addition, the veins stood out on the back of some people's hands are obvious:
First, manual workers, especially those who work hard. Because of long-term physical labor, these people's metabolism is faster than that of ordinary people, and their blood circulation is also very fast. Over time, the subcutaneous meridians will become thicker, the visual range will be expanded, and the veins will become more obvious.
Second, fitness has a long history. Like heavy manual workers, people with fitness hobbies exercise a lot and pursue muscles, so their blood vessels will expand because of the accelerated blood flow, and their veins will be obvious.
This kind of person's blue veins on the back of his hand are obviously not caused by disease, so don't panic. But if you don't belong to these people and the veins on the back of your hand suddenly burst, then you should consider your physical condition. Traditional Chinese medicine believes that the blue veins on the back of the hand are obviously raised, which is a manifestation of sub-health of the body. Because the veins stood out suddenly, it is likely that poor blood circulation leads to varicose veins, indicating that there are large blood vessels blocked in this body. If left unchecked, edema and venous injury will occur, and in severe cases, thrombosis will occur, which will affect people's normal life and work.
So in daily life, we must pay attention to the cultivation of healthy living habits. People who are mainly teachers, policemen and waiters should avoid sedentary or standing for a long time, which is not conducive to blood return and induces varicose veins of lower limbs. Insist on soaking feet with hot water every day and keep the habit of exercise.
