harm

1, increasing the chances of trauma and infection.

Wearing shoes barefoot exposes a lot of foot skin, which increases the chances of trauma and mosquito bites. Some people also get bleeding blisters on their feet because of barefoot shoes. Dust and germs in the air directly attach to the skin, which will not only make the feet dirty, but also cause infection if you encounter wounds such as worn blood bubbles.

Step 2 catch a cold

The fat layer of the foot is thin, the heat preservation is poor, and it is farthest from the heart and the blood supply is poor, so the temperature of the sole skin is the lowest and it is easy to catch cold. Once the foot catches cold, it can reflexively cause the capillary contraction of the upper respiratory tract mucosa, so that the resistance is obviously reduced, and the bacteria in the air will take advantage of it and cause many diseases such as colds. Especially when it rains, barefoot is more likely to catch cold, which will cause stomach pain, low back pain and dysmenorrhea in women.

3, cause keratinization and dermatitis

Without the protection of socks, the result of frequent "close contact" between feet and shoes is that it is easy to make the cuticle of the heel and other parts that often contact shoes longer and thicker, which greatly increases the probability of calluses (cocoons) and corns. In addition, some people walk barefoot for a long time, and the friction parts of shoes such as instep and toes are prone to skin redness, papules, blisters and other symptoms. This is a kind of contact dermatitis, which is caused by skin allergy to leather, rubber and other footwear.

4. Increase the risk of skin cancer

Long-term and large-area direct exposure to sunlight will stimulate the skin to produce a large number of oxidative free radicals, destroy skin cells, accelerate the oxidation reaction of melanin production, make the skin dull, rough and inelastic, and also reduce the skin's resistance. Some data show that sandals, sandals and other shoes are easy to increase the risk of skin cancer, because they directly expose their feet to the sun in a large area, and people usually don't put sunscreen on their feet or do regular inspections.

5, prone to fungal infection

People's feet are prone to sweat in hot weather, so wearing shoes directly without socks, especially wearing leather sandals, plastic sandals or even travel shoes with poor air permeability, will make the skin of feet directly soak in sweat, and the parts where feet touch shoes will turn white after a long time. At the same time, because fungi are easy to grow in hot and humid environment, it will also cause fungal infection of feet.
