Why do feet stink in autumn?

There are several reasons for smelly feet * * *:

1. Humid environment: The soles of the feet are sweaty. The sole of the foot has more than 600 sweat glands per square centimeter, 2 ~ 4 times more than other parts of the body. There are about 250,000 sweat glands in total, which can secrete nearly 500 ml of sweat every day. Besides water and salt, sweat also contains lactic acid and urea. When the water content is high, it is very beneficial to the reproduction of bacteria and mold.

2. Hot and closed space: When the shoes are tightly worn and the ventilation is not good, the PH value of the skin surface will change from the original PH4.4 to around PH7, and carbon dioxide gas will be released, which is the most suitable environment for some bacteria to grow on the soles of the feet.

3. Bacterial reproduction: due to the superposition of one or two factors, the foot skin bacteria breed. These bacteria can decompose skin keratin, urea and lactic acid in foot sweat, and form various smelly methionine, such as (1) Brevibacterium, which can decompose keratin and form methyl mercaptan. The smell of this metabolite is very similar to that of cheese fermentation. (2) The fat components in sebum are decomposed by Staphylococcus aureus, which will form short-chain fatty acids. (3) Urea in sweat is decomposed into ammonia by bacteria. These smells are mixed together and tightly locked in airtight socks, which will form unpleasant foot odor.

4. Breeding of mold: A hot and humid environment will breed mold and form foot odor, commonly known as Hong Kong foot. The symptoms of beriberi are very diverse. Not all beriberi smells. The most common type of athlete's foot that produces foot odor is athlete's foot with wet skin and rotten skin between toe tendons, which is the most serious.

5. Too thick old cutin: Too thick old cutin, under the infiltration of sweat, will become the nutrient source needed by bacteria and mold, promote the reproduction of bacteria and mold, and worsen the formation of foot odor.

Second, what external factors contribute to foot odor?

1, excessive sweating on feet. It is more common in teenagers, which may be due to unstable autonomic nervous function, such as excessive excitement of sympathetic nerves caused by emotional tension, or excessive sweating of feet.

2, some diseases of the foot, such as tinea pedis between the toes and other skin diseases.

3, often wear rubber overshoes, nylon stockings and other shoes and socks with poor air permeability.

4. Or some people don't pay attention to the cleanliness of their feet. The temperature of foot skin and the humidity and dander formed by sweat constitute the suitable conditions for the growth, reproduction and corruption of microorganisms (especially anaerobic bacteria) on foot skin. In addition, uric acid, lactic acid and other organic substances in sweat decompose, resulting in stench. If you don't pay attention to the cleanliness of your feet, it will contribute to foot odor.

5, sweaty feet, and sweat evaporation is not smooth, resulting in whitening and soaking of the epidermis, especially between the toes. Severe sweating can cause blisters, erosion or hyperkeratosis, and it is also easy to cause fungal infection and foot odor.

6. After the damaged skin is damaged, it will affect the skin's defense function, making it easier for pathogenic fungi to invade and settle down, causing foot odor.

7. Obese people are more likely to sweat, and their toes are wet and soaked, which induces foot odor.

It is best not to wear the same pair of shoes for two consecutive days. They need time to dry completely. Put the shoes in a ventilated place to dry thoroughly. For example, if you put your shoes outdoors, first take off the insoles and dry them in the sun. 6. If the smell of shoes can't be removed even with deodorant products, then throw them away. 7.
