How to Keep Feet Healthy

When it is hot, many people are willing to wear shoes without stocking. But, Lu Tao in a hospital of Tianjin, he tells us that it is harmful for people's health if they wear shoes like that.
First, people are apt to get hurt. Because people do not wear stockings, we can see their feet's skins. Therefore some insects will hurt their feet. They do not put on stockings, and it can bring harm to their feet. So the bacteria in the air will adhere to the skin of feet. If there is a wound on the feet, it will infect the bacteria.
Second, the skin will be "roasted" by the sun. Ultraviolet rays in the sun can hurt the skin and produce a lot of radicals. Then the sells can be hurt by the sun. Therefore people's feet's skins will become resilient and rough. The resistance of the skins reduces. The skins of feet will be hurt by the strong sunshine. So it is risky for people to get cancer.
Third, it brings dermatitis to people's feet. If we do not wear socks, the feet and shoes often rub. A long time later, there will be calluses or corns on people's feet. Sometimes, people get other diseases because they do not wear stockings. That's because that they often do not wear socks. Sometimes their feet are oversensitive to the shoes made of leather or rubber. We can regard this kind of allergy as an illness.
Forth, the feet are easy to be infected by funguses. If it is hot, our feet often perspire. So we do not need stockings when we wear shoes. In summer, we often wear those plastic sandals or sneakers. These shoes have bad air circulation. Therefore our feet often bath in the sweat of feet. The funguses are easy to develop in the damp and hot places. So feet can be influenced by the bacteria.
Fifth, feet are not warm even in summer and feet can be hurt by coldness. Feet are special organs in our bodies. The temperature of our soles is very low and the feet are easy to be cold. At the same time, people are easily influenced by the bacteria in the air. Next, people will infect some other diseases. When it rains, the stomachs and loins can be painful. If you are a girl, you may get menstrual colic.
So, Lu Tao gives us many advices. In summer, we should pay more attention to our feet. People must keep their feet clean and tidy in summer. Thus we can not ignore the functions of socks. The socks are between feet and shoes. They construct a zone which is good for our feet. When it is hot, we should choose those cotton socks which are thin. You also can put a cotton sole into the shoes. On one hand, the stocking can protect people's feet. On the other hand, the stockings are able to endure the frictions. If their diseases are terrible, they must go to see a doctor. So even in summer, we should wear stockings to protect our feet. As long as we pay attention to this point, we can keep our feet healthy.
