Most of us have suffered from foot perspiration and odour from time to time, yet for some people, sweaty feet (along with sweaty palms and armpits) are a persistent problem, which can be embarrassing and uncomfortable. For some people, this can affect their day-to-day life considerably, and result in decreased social contact with others. But the condition is treatable.
There are more sweat glands per inch in our feet than anywhere else in the body. Their function is to keep the skin moist and supple and regulate temperature when the weather is hot, if you have an unnaturally high temperature or while exercising. They secrete all the time, not just in response to heat or exercise, like elsewhere in the body.
Excessive sweating, also known as hyperhidrosis, has a lot to do with how the sweat glands in the feet work. With 250,000 sweat glands, feet do tend to sweat more than other parts of the body, but with a daily hygiene routine few people should suffer from the embarrassment that it may cause.
Sweaty feet (along with palms and armpits and the face/scalp) tend to be symmetrical. The exact cause is unknown but due mainly to overactive sweat glands. In some cases, the cause can be genetic.
Possible other causes include stress on the foot, sometimes caused by a structural problem, or because the foot is under strain or tired, for example when you have been standing on your feet all day.
