What causes body odor?
Obviously sweat.
No.
Sweat is odorless.
What?
But how is that possible?
Our skin contains two types of sweat glands, eccrine glands and apocrine glands.
Eccrine glands are present all over our body.
They produce sweat which is mostly water.
Whereas, apocrine glands are concentrated in regions such as ear canals, armpits, etc.
They produce thicker sweat which has proteins.
Can I eat these proteins and become a bodybuilder?
Just listen.
We know that millions of bacteria are normally found all over our skin.
When apocrine glands produce sweat.
The bacteria on our skin breakdown the proteins in that sweat.
Releasing unpleasant smell which we call as body odor.
