Why do I sweat so much? The skin is composed of three types of glands which
produces secretions called sweat. Generally speaking,dermatologists believe that
normal secretions of all three glands are odorless,or nearly so,until they are
decomposed by normal skin bacteria. The odor Potential is different for each gland.

The eccrine glands are the major source of perspiration but are relatively unimportant
as a contributor to body odor. These glands contain very low amounts of organic
materials for which bacteria can act upon. Eccrine glands primary job is to help control
body temperature,and are usually inactive until: the temperature is
high,exercising,nervous tension,emotional stress,or embarrassment comes into play.
They produce  perspiration in certain parts of the body such as the axillae
(underarm),palms,soles,and may be triggered by certain foods containing hot spices.

The next gland is the apocrine gland. These glands become active after puberty and
remain so as long as sexual activity continues. They are rich in organic material which
makes them a major source for
bacteria interaction and body odor. These glands are
concentrated in the axillae,around the nipples,and genital area. An Idea places for
bacteria growth due to perspiration and lack of quick evaporation of moisture. "There
is some evidence that in women the activity of the apocrine can vary with the
menstrual cycle. These gland are stimulated by emotional stress,such as fear or
pain,and especially by sexual excitement; their activity is not increased by hot weather
or exercise."   


The Sebaceous glands are the third type of skin gland. It's main purpose is to keep the
skin lubricated with an oily material called sebum.They play a relatively small role in
body odor for people that bathe regularly. So in view of what is known about body
odor,there are two obvious approaches to preventing it: Impede bacteria action,and
reduce sweating. Deodorant soaps were good for the removal of
bacteria;antiperspirants did both. But according to an
old Consumers Union (CU)
report,antiperspirants on the market at that time were not very affective for people
having a condition known as hyperhidrosis, an abnormality in which large amounts of
sweat is produced by the underarm  glands and sometimes by the glands of the hands
and feet. This kind of abnormal sweating was thought to be due to over activity of the
sympathetic nervous system. Medications were usually of no use,and in rare
instances surgery may have been required.  At that time,no satisfactory solution was
known.

Excessive sweating,particularly of the feet, can be a serious problem for many people.
It has been known to break up friendships as well as marriages. Odor of the feet is
cause by bacteria interacting with sweat on the feet,and since the feet tend to retain
moister,they're a prime breeding ground for  fungi,which can cause inflammations
such as athletes foot. People that have overly sweaty feet "should whenever
possible,wear sandals or open weaved shoes,and hose of cotton or wool rather than
nylon. Liberal dusting of the feet with plain talc helps to absorb sweat and discourage
the growth of fungi. Lambs wool tucked between the toes keeps them apart and aids
in the evaporation of perspiration." But for general perspiration control,an
antiperspirant would  be a better selection than a simple deodorant,since it does all
the same things and reduces perspiration as well. Most people find one of the
aluminum salt formula satisfactory,although it may be necessary to try several brands
to determine which works best for you.
