1, foot odor is caused by what? Simply put, foot odor is the product of foot sweat + bacteria. Sweat glands on the feet is more than other parts of the body, will secrete sweat every day. And in the shoes and socks wrapped, these feet sweat and not easy to evaporate, so in this relatively humid environment, a variety of bacteria breeding, and eventually decompose sweat and produce a variety of smelly metabolites. 2, why wash your feet every day, change socks still stink feet? Either the feet are not kept dry, or not do a good job of sterilization. We can review their cleaning habits to see if these places are not done: (1) feet washed clean enough, especially the toe seam, the sole; (2) after cleaning the feet did not dry in time; (3) shoes and socks are not timely sterilization cleaning (80% of people are not really good sterilization work); (4) feet sweat too much; 3, foot odor will be contagious? Simple foot odor, everyone may exist, that is too much foot sweat + bacteria, as long as you pay attention to foot cleaning is good, and will not be contagious. It is contagious is foot odor (also called tinea pedis), but foot odor and foot odor are not the same thing. Tinea pedis, the most common superficial fungal infection of the skin, is mostly caused by the fungus Trichophyton rubrum. In addition to smelly feet, patients may have itchy feet and rice-sized blisters on the crevices of the toes, edges of the feet, or soles of the feet; there may also be peeling and oozing between the heels and toes. Trichophyton rubrum is very easy to grow and reproduce and is widely distributed on various household items, such as slippers, socks, bathtubs, and floor surfaces. Therefore, if you wear slippers with bare feet or step on an unclean pool, bathtub, or floor, there is a real possibility of being infected. Moreover, foot odor may spread to your hands, toenails, thighs and buttocks if you scratch with your hands …… 4. Is “foot odor disease” and “foot odor” the same thing? The two are completely different in terms of symptoms and causes. Foot fungus belongs to a skin disease caused by fungus; while foot fungus is a systemic disease caused by vitamin B1 deficiency in the body, which mainly occurs in people who have been eating refined white rice as the main food for a long time and lack other side food supplements. Foot disease mainly affects the digestive, nervous and circulatory systems, and patients may experience symptoms such as abdominal discomfort, constipation, lower limb weakness, muscle aches, palpitations and tachycardia. During the exacerbation of the disease, some patients may also develop foot symptoms such as numbness in the ankles and feet and edema in both lower limbs. Vitamin B1 supplementation is the key to the treatment of beriberi. In addition to taking vitamin B1 supplements under the guidance of a doctor, patients with mild cases can eat more sunflower seeds, peanut kernels, bacon, pork (lean) and other foods in their diet. 5, can soaking feet with salt, garlic, ginger …… cure foot odor? These methods do have a little effect on mild foot odor, because ginger, garlic and other items themselves have some bactericidal effect. But these antiseptic and antibacterial effects are far from soap and disinfectant, if you are willing to abandon these messy “spices”, with soap to wash your feet well, can achieve the same (or even better) effect. However, this way to get rid of foot odor is temporary, and if you follow up with unclean shoes and socks, it will produce odor again.
