Hot days, many people are willing to wear shoes barefoot. However, Lu Tao, director of dermatology at the Affiliated Hospital of Tianjin Armed Police Medical College, pointed out that there are five kinds of health risks in this method of wearing shoes.
The first is to increase the chance of trauma and infection. Barefooted shoes expose a large amount of skin on the foot, often being bumped or bitten by mosquitoes. Walking on too much will also make the foot wear blisters; bacteria in the air will adhere to the skin, and if the skin has a wound, it will cause infection.
Second, the skin is directly "burned" by the sun. Ultraviolet rays in the sun will stimulate the skin to produce a large number of oxidized free radicals, destroy the skin cell tissue, accelerate melanin production, make skin pigmentation, roughness, loss of elasticity, and reduce skin resistance. According to statistics, a large area of ​​the skin on the feet of the barefoot sandals is directly exposed to sunlight, increasing the risk of skin cancer.
The third is to cause skin keratinization and dermatitis. The feet and the shoes are often in direct contact with each Other, making it easier for the heel, toes and other parts of the skin that are often in contact with the shoes to grow thicker and thicker, which increases the chance of having a pimple, ie, “scorpions†and “cornsâ€. In addition, some people walk with barefoot shoes for a long time, and parts of the instep, toes, etc. that are in friction with the shoes are prone to skin redness, pimples, blisters and other symptoms. This is because the skin is caused by allergies to materials such as leather and rubber. A contact dermatitis.
The fourth is prone to fungal infections. People's feet are prone to sweating in hot weather. Wearing shoes without socks, especially wearing breathable shoes such as plastic sandals and travel shoes, will allow the skin of the feet to be directly immersed in the sweat. The fungus is in a hot and humid environment. Prone to growth, foot fungal infections can occur.
The fifth is cold caused foot disorders. The fat layer of the foot is thin, the heat preservation is poor, and the blood supply is poor. Therefore, the skin of the sole of the foot has a low temperature and is easily exposed to cold. Once the feet get cold, the capillaries of the upper respiratory tract can be reflexively contracted, resulting in decreased resistance to the respiratory tract. The bacteria in the air will take advantage of it and cause various diseases such as heat cold. When it rains, bare feet get cold, it can also cause stomachaches, lower back and leg pain, and women can develop dysmenorrhea.
Lu Tao suggested to people that summer should pay attention to the cleaning and maintenance of the foot. Try not to wear shoes with bare feet. The socks can form a “sand†between the skin and the shoes that absorbs and breathes. When the weather is hotter, you can choose thinner. Cotton socks can also be filled with cotton insoles in the shoes. This absorbs sweat and protects the skin while also making the feet resistant to rubbing. Those who have had contact dermatitis should stay away from allergens and have exuded, eroded, and rashed feet. They need medical treatment in time.
