What Does Excessive Sweating Indicate?

Excessive sweating is a common condition that affects millions of people in the world. There are several different types of excessive sweating, some more serious than others and all with distinct symptoms and causes.

What Causes Excessive Sweating?

Physiologically speaking, there are two types of sweat glands: eccrine and apocrine. Eccrine sweat glands produce water-soluble substances such as salt (sodium chloride), fructose, urea (a waste product from protein metabolism) and other components found in sweat which evaporate when outside temperatures rise above about 30 degrees Celsius or 86 degrees Fahrenheit. Apocrine sweat glands produce compounds called pheromones which give off an odour; this type of gland does not contain salt but contains proteins such as keratin, arachidonic acid and zinc salts that help protect skin cells against sun exposure by protecting them from UV light damage.[4] Both types work together to rid body surfaces at rest of potentially harmful bacteria through secretion onto hands and face during hot weather,[5] but extra moisture created by overactive eccrine or apocrine glands can lead to excessive sweating when it gets trapped within clothing or on skin.[6] Under certain conditions, even the perception that one’s environment is too warm may trigger an increase in perspiration [7]. Certain medications [8], psychological factors [9], hormonal cycles,[10] hereditary predispositions[11], infection[12][13][14][15],[16],[17
