We commonly think of the armpits as being the center for all sweat… but actually, the foot has the highest density of sweat glands on the body. “Each foot has more than 250,000 sweat glands,” according to Denise Reynolds RD, so you can imagine how much sweat a typical person produces in one day. Small quantities of sweat are secreted about six or seven times per minute, which produces a whopping PINT of sweat, per foot, per day!
However, some of us are naturally sweatier than others. An estimated one percent of the population suffers from some form of hyperhidrosis — be it the hands, feet, or underarms. “It is unknown whether it is an over-activity of the sympathetic nervous system or the sweat glands themselves,” reports board-certified podiatrist Dr. Mark H. Tompkins of Texas. However, he notes that hereditary factors “play an important role.”
People with hyperhidrosis can use a topical gel or cream containing aluminum chloride as an antiperspirant. Though controversial, Botox injections have been used, with effects lasting from three to nine months. Another experimental treatment involves sending low-grade electrical current through feet submerged in water. Surgery is possible, but not recommended by the International Hyperhidrosis Society, due to the potential risks involved.
