Foot odor is mainly caused by foot sweat, which contains urea. When bacteria grow, it will produce some unpleasant smells, which is ammonia. Foot sweat also contains propionic acid, which is the metabolite of amino acids decomposed by Propionibacterium. Clinically, the chemical structure of propionic acid is similar to that of acetic acid, which is a colorless liquid and smells like vinegar.
In addition, bacteria can digest dead skin on feet and convert amino acids into methyl sulfuric acid. Methylsulfuric acid is a colorless gas, but it has a special rancid smell. It is suggested to pay attention to the hygiene of shoes and socks, keep feet dry, try to choose shoes with good air permeability and go to the hospital dermatology department for treatment.
Method for relieve foot odor
Soaking feet and using warm water every day can really soften cutin, promote blood circulation of feet, and help reduce sweating and bacterial growth of feet. It is also a good choice to add some antibacterial drugs such as tea tree essential oil and menthol, which can enhance the effect of soaking feet. Breathable shoes and socks are also an effective way to reduce the growth of bacteria in the feet. Breathable shoes and socks can keep feet dry and avoid bacterial growth.
It is also important to change shoes and socks in time. Wearing socks for a day will absorb sweat and bacteria on your feet. If you don't change them in time, bacteria will breed. Therefore, it is recommended to change clean socks every day. Keeping feet dry is also an effective way to reduce bacterial growth. After taking a shower, you can gently dry your feet with a clean towel to avoid leaving moisture and allowing bacteria to grow.
