First look at the color of the soles of the feet. Five-color disease differentiation is one of the contents of traditional Chinese medicine. These five colors are green, red, yellow, white and black. Traditional Chinese medicine believes that the normal color of the sole of the foot is red, which means that the color of the foot should be "smooth" at best. If the above colors appear, you'd better go to the hospital for examination. Secondly, look at the color of toenails. Feet are far away, toenails are farthest, just like the top of Mount Everest.
If the toenails are smooth and shiny, it means that the human body has good blood circulation. People who live a long and healthy life will have healthy pink toenails. At the same time, the white crescent on the toenail accounts for about 1/5 of the toenail. If you press the crescent to turn white, you will find that it will slowly recover after releasing the crescent. This shows that the blood circulation is not good. This is called red pressure test, which can reflect the blood circulation of the foot. If you find your toenails pale and colorless, then you should consider malnutrition or anemia.
At this time, you should pay more attention to your diet and ensure that you get enough calories every day. At this time, we should pay attention to exercise more to prevent sedentary. Finally, look at the color of the toes. Healthy toes and abdomen should be smooth and full. Old people's feet are easy to catch cold, mainly due to insufficient kidney yang or improper heat preservation. Such people should eat more warm food, such as mutton, garlic, ginger and so on. , improve their cold resistance.
