Today we will go a bit off topic than normal, but I feel it is something that really needs to be covered on a fitness blog. What is that you ask? It is why does sweat smell so bad and do people smell their own sweat odors? My inspiration comes from a muscle head that I was working out next to today at the gym, I kept glancing at him as he was throwing around some serious weights.He kept glancing at me through the mirror and I imagined that he thought that I was impressed or taking back by his beauty, but instead I was amazed that any person could smell so rank and still have a pulse.
Why Sweat Really Stinks?Bromhidrosis (another word for body odor) happens at puberty because of increasing hormones called androgens. These hormones are not active until puberty, which is why body odor wasn’t a problem when you were a kid.
While sweat itself is virtually odorless, bacteria use it as a breeding ground and multiply rapidly. What you smell is the products related to bacteria breakdown of keratin protein on the surface of your skin. Sounds disgusting, doesn’t it? Chalk it up to an unpleasant fact of life!
When you work out or move around in the heat or sun, your body produces sweat. Sweating is the body’s way of regulating temperature. When sweat meets the bacteria on the surface of your skin, it produces an odor. That smell is what we call body odor (or B.O. for short).

Can we Smell our own sweat?
The answer isn't so simple, but I found an article for all my smart reader that may shine some light if it makes sense to you drop me a comment and dumb it down for the less nerdy folks that visit this blog.
MHC peptides are found on the surface of almost all cells in the human body, helping inform the immune system that the cells are ours. Because a given combination of MHC peptides—called an MHC type—is unique to a person, they can help the body recognize invading pathogens and foreign cells. Over the past 2 decades, scientists have discovered that the molecules also foster communication between animals, including mice and fish. Stickleback fish, for example, choose mates with different MHC types than their own. Then, in 1995, researchers conducted the now famous "sweaty T-shirt study," which concluded that women prefer the smell of men who have different MHC genes than themselves. But no studies had shown a clear-cut physiological response to MHC proteins.
