Why does sweat smell bad?
On the whole body, sensors feel body temperature and signal to the brain if it is time to regulate it. This is done primarily by sweating. However, there are two types of sweat – heat sweating and stress sweating.
Heat sweat, for example excreted during exercise, comes from eccrine glands and stress sweat from something called apocrine glands. There is no big difference between the sweat secreted, but usually you can say that the apocrine glands (stress sweat) produces more proteinaceous sweat – something that bacteria and fungus like to eat. The reason that foot sweat is such a big problem is mostly because there are more bacteria and fungi in dark, humid environments – such as shoes.
When the bacteria are then saturated, they emit sulfur-like substances that, for us, smell unpleasant. What SmellWell does is to remove the moisture where bacteria and fungi thrive to eliminate the problem before it occurs.
