Sweating happens just about anywhere – when you’re working-out at the gym, when you’re facing an audience to deliver a presentation, or when you’re simply taking a walk on a hot day. Perspiration contains mainly water and salt and trace amounts of electrolytes that help regulate the balance of fluids in the body. The purpose of sweat is to help cool the body down. But, there are people whose perspiration systems function differently, resulting in either too little sweating or too much.
Perspiration that is triggered by intense feelings occurs on the face, palms, underarms and the soles of your feet. Your moods, certain foods and beverages, hormones and medication can all affect the way you smell.
For many of us, sweating is simply bothersome. The odour that occurs with it is sheer embarrassment. Although sweat doesn’t smell (if you are looking after your body) it smells when it comes in contact with the bacteria on your skin. In fact you do not even need to sweat much in order to create odours, I have notoced that when I have a long drive, if I do not shower before my pits can be a bit whiffy the following morning. This can be due to having arms down for prolonged periods resulting in the perfect dark, slightly damp, unaired environment that these bacteria love to thrive in.
Types of sweat glands
There are two types of sweat glands on your skin: eccrine glands and apocrine glands. Eccrine sweat glands that number between 2-5 million are present over most of your body and open directly on the surface of your skin. As they secrete perspiration onto the surface of your skin, your body temperature cools down as the sweat evaporates.
Apocrine glands secrete a fatty sweat directly into the tubule of the gland. When a person experiences stress, the wall of the tube contracts and the sweat is pushed directly onto the surface of the skin where the bacteria begin breaking it down. The bacterial waste products are what causes the strong odour.
