Hippos, Horses Sweat … and More Smelly Secrets

“Perspiration in the animal kingdom is often not just a simple sweat and stink process, as new research demonstrates.”

Latherin: A Surfactant Protein of Horse Sweat and Saliva

“Horses are unusual in producing protein-rich sweat for thermoregulation, a major component of which is latherin, a highly surface-active, non-glycosylated protein.”

How Body Odor Works

“Raise your hand if you’ve ever been on a bus or in any other cramped quarters next to someone who just smelled bad. On second thought, never mind.”

No sweat? If you have this gene, you may not use deodorant

“Ah, the sweet smell of science: An English study published Monday confirms a link between an underarm odor gene and deodorant use.”

Dry earwax? It’s genetic

“Genetics researchers have uncovered the key gene behind the mystery of human earwax. Finally.”

Eliminate body odor for good

“Body odor is a combination of sweat and bacteria. Sweat is actually odorless; it is bacteria that live off perspiration on our body that create the bad smell.”

Abnormal Absence of Sweating

“An abnormal lack of sweat in response to heat may be harmful, because sweating allows heat to be released from the body. The medical term for absent sweating is anhidrosis.”

I'm a believer now. Stopped for about a month ago and I think I stink at the end of the day but everyone I ask said smell good to them. So either I'm around a bunch of people that don't want hurt my feelings or science nailed this one!

Holy shit. I have pretty dry earwax. And I am known for never smelling bad. I think I might have that weird sweat gene.

I activated my discreet sweat, bugs don't bother me much, I heal reary fast, and I have a greater sense of connection to the universe. Immune system celebration after I decided I no longer would like to eat animal products. Simply because it is logical and rational, also meditation has helped real eyes realize real lies.

Thanks for the video content! Apologies for butting in, I would appreciate your initial thoughts. Have you heard the talk about – Sayerdsan Excessive Sweating Secret (do a google search)? Ive heard some extraordinary things about it and my BF at very last said good bye to the annoying excessive sweating issue with it.

Juan Richard July 25, 2015 - 7:10 PM

Are we sweating when we're swimming?

Wiz August 1, 2015 - 5:05 PM

Smelly sweat could easily be fixed if our sweat contained antibiotics. BTW why does sweat leave a yellow residue in some people? Is it urea? But don't we have the kidneys to filter that out?

Samara E June 7, 2021 - 10:14 PM

Listen, I have to at minimum point out that Cynthia Yulesin's approach is where a lot of us finally discovered the answers. Its effects are almost immediate, and it works after just making use of the method for 48 hours or so.
