ATLANTA, Aug. 8 /PRNewswire/ -- As bodily functions go, sweating is highly underrated. Sweat is blamed for wet handshakes in job interviews, ruined clothes on first dates and the terrible stench of athletic locker rooms. However, Russell Athletic's Sweatxpert, Dr. Larry Kenney, explains that physically active people cannot function without sweating.

Being drenched in sweat is not appealing. However, sweat actually acts as your body's radiator by protecting you from overheating. By wearing performance material, such as Russell Athletic's Dri-Power(R) clothing, the benefits of sweat can be maintained while still keeping a person dry and comfortable. According to Kenney, during even moderate exercise, body temperature would increase at a rate of one degree Celsius every six to seven minutes without sweating. This would cause the body to overheat quickly and can create potentially dangerous health problems. Evaporation of heat puts the brakes on the body's temperature climb, but exercisers should be cautious of extreme temperatures that can still cause heat exhaustion. "Two to five million eccrine glands, producers of the good sweat that cools the body during exercise, secrete sweat directly onto the skin surface and are scattered over the body surface," said Sweatxpert Kenney. The distribution of eccrine sweat glands is non-uniform, varying from less than 50 to as many as 800 glands per square centimeter of skin. The highest densities of eccrine sweat glands are found on the palms of the hands and soles of the feet. With millions of sweat glands, managing sweat becomes an important task. Products like Russell Athletic's Dri-Power(R) and the latest innovation, Dri- Power(R) Fleece, performance fabric can actually bring eccrine sweat to the surface of the material in order to evaporate more efficiently and effectively. Kenney explains that while performing heavy exercise in hot conditions, the body can lose more than two liters of sweat per hour. In fact, with adequate fluid replacement, maximal daily sweat rates under severe exercise conditions can be in the range of 10 to 15 liters! However, by using Russell Athletic's Dri-Power(R) clothing, those 10 to 15 liters will be wicked to the clothing's surface to evaporate more quickly. Eccrine sweat is odorless, colorless and relatively dilute. In fact, if humidity is fairly low the sweat produced from eccrine glands evaporates quickly, making the body cooler. It is the other sweat glands, called apocrine glands, which secrete sweat into hair follicles causing odor and clothing stains. Although embarrassing stories about sweat run rampant, sweat does not deserve its bad reputation. After all, wouldn't it be much more embarrassing to overheat and faint in public?
