It goes right up there with bad breath. This fear causes us to religiously brush our teeth and slick on our deodorant every day, often more than once. Our bodies produce many secretions, sweat glands produce a large proportion of these and most of our sweat glands are concentrated in our armpits. The content of our sweat varies depending on a number of influences, some of which include diet, environment, genetics and hormones.
Sweat is also a common source of pheromones.
Pheromones are airborne, odorless molecules that act as chemical signals. They are believed to influence our communication, behavior, and physiological responses. Only recently did researchers discover that the VNO actually functioned. The VNO sends messages to specific areas of our brains that control different functions. The effect pheromones have been found to have are amazing and explain a variety of subconscious behaviors.
