In winter, many people will have this problem: obviously in the summer there is no foot odor, but in winter found after taking off shoes feet emit odor. This is precisely because the shoes worn in winter form a relatively confined space, easy to encourage the growth of bacteria, these bacteria decompose organic matter in sweat, the metabolites released contain odor, thus forming foot odor. Winter foot odor bacteria growth is the culprit With the temperature gradually going low, many people wear boots, boots or a variety of warm shoes, feet are closely wrapped in shoes, which undoubtedly for the culprit of foot odor – “bacteria” provides conditions for growth. Many people think their feet stink due to foot sweat, in fact, the main smell of foot odor is not from sweat. Everyone’s feet have parasitic flora, generally in a state of balance. But in closed shoes, sweat is more difficult to disperse, coupled with the body temperature of the human body, creating a warm and humid environment in the shoes. In such a special environment, certain flora will multiply especially fast, and then break the balance of bacteria. The proliferating bacteria break down keratin and mix with urea and lactic acid in sweat to produce an unpleasant odor. The worse the ventilation of the shoes, the worse the foot odor. This is why foot odor is rarely a problem when wearing sandals in the summer. Pay attention to cleanliness to help reduce foot odor Many people often confuse foot odor with foot fungus. In fact, the two are not the same, foot odor is a very common fungal infection skin disease, usually accompanied by sweating, foot odor, itchy feet and other symptoms, serious patients will appear between the toe skin, blisters, ulcers or fissures and other symptoms. Foot odor is also divided into physiological foot odor and pathological foot odor. If the foot odor is only caused by wearing non-breathable shoes and socks, most of them are physiological foot odor. As long as you pay attention to cleanliness, keep the skin of your feet dry, change your socks and wash your feet every day, and change to more breathable shoes and socks, it will help alleviate the problem of foot odor. However, it is important to note that if you do not pay attention to cleanliness in the case of sweaty feet, and your feet are wet for a long time, it is likely to induce pathological foot odor. If the foot odor is caused by foot fungus, etc., you need to actively cooperate with the treatment to remove the cause of the disease in order to reduce or eliminate foot odor. There are few people who are troubled by foot odor in winter, so there are various experiences to reduce foot odor. Some people say that at least two pairs of shoes should be prepared, and the smell will not be so great if you change them every day. This kind of experience can only say that there is a slight improvement, but not very useful. The root cause is the proliferation of bacteria. Therefore, you can use professional deodorant drugs and supplies, the use of antibacterial drugs to inhibit the reproduction of bacteria on the feet, so as to achieve the purpose of deodorization. You can soak your feet in an antiseptic solution (such as potassium permanganate solution or urotropine solution) to remove the parasitic bacteria from your feet and remove the odor.
