Heat, Temperature and Sweating Mechanism

The body temperature is kept at a constant value with heat transfer. Conduction, convection, and radiation, as well as evaporation, play a role in this regulation. The heat is removed from the hot body with evaporation. This is achieved via sweat glands. Three types of glands; eccrine, apocrine, and mixt type are found in the human skin. Sebaceous glands also open to apocrine sweat canals. These glands make the skin surface sebaceous during evaporation. The sebaceous surface protects skin from pathogens. There are odor and coloring on the surface of the skin which has the apocrine, the mixt type sweat glands and the sebaceous glands. Various molecules have responsibility for the coloring. The fundamental cause of odor is bacteria. Various molecules are responsible for odor formation. Eccrine sweat glands only provide sweat release. Peripheral and central systems play a role in regulating sweat release. Hyperhidrosis is a disorder of excessive sweating due to over-stimulation of cholinergic receptors on eccrine glands. Hyperhidrosis is caused by extreme central nervous system induced stimuli to the eccrine sweat glands which found in the hands, feet and armpit skin. Hyperhidrosis is not a life-threatening disease but affects one’s social life negatively. Some drugs, ETS surgery, Botox application and iontophoresis are used for hyperhidrosis treatment. Iontophoresis which should be applied first is a galvanic current therapy, and its side effect is almost none
