Ugh.
Why do feet stink?
Let's face it.
We probably all know
at least one person
who clears out the room
every time they walk in
and take off their shoes.
And it doesn't matter how clean
we are, how hygienic we are.
Even if you've
got some OCD thing
where you wash your
feet 100 times a day,
the point of the
matter is, if you
run a mile, then
your socks, shoes,
and feet will stink afterward.
Why are feet the stinkiest
part of the human body?
Sweat.
With more than 250,000
sweat glands per foot,
our feet just tend to perspire
or sweat more than the rest
of our body.
Sweat doesn't smell like feet.
I'm not, like, a sweat
doctor, but I know that much.
Sweat is essentially
salt and water,
so it doesn't have its
own distinctive odor.
The bacteria, however, does.
Bacteria is all over
your skin right now.
Don't think about it too much.
Don't get freaked out.
It's normal.
This bacteria
loves to eat sweat.
When bacteria is
eating sweat, it's
excreting waste--
bacteria poop--
that produces this distinctive
odor-- the smell is bacteria
poop-- that some would associate
with good cheese or smelly
feet.
What I'm saying is that you're
smelling poop from bacteria.
I'm not going to judge you.
Hey, we've got sweat glands
everywhere, you know.
Why don't our entire
bodies smell like feet
every time we get nervous?
Just for comparison,
the human hand
has a comparable
number of sweat glands,
but it doesn't smell like feet.
So, why is that?
The answer is all around us.
Because it's air.
Eh?
OK.
The bacteria, the
sweat, the waste.
It all can escape through
the air and diffuse,
so we're less likely
to smell terrible.
Feet, however, are coated
in a couple of layers.
We got socks-- Why do feet
smell?-- and we've got shoes.
Instead, it's kind of collecting
in your feet, on your socks.
It's pretty gross.
So, then the next
question would be,
why do some people
have such stinky feet.
Some people just sweat more.
It's one of those varying
physiological things
about the great
human experience.
This is also why sometimes
your feet might smell terrible
and then sometimes they
don't smell that bad.
Keep your shoes on.
All right.
That's it.
Thank you so much for watching.
We hope you guys enjoyed it.
