NEUROSCIENTIST: This HABIT Makes YOU UNATTRACTIVE | Andrew Huberman

a lot of people were really overweight

or even mildly overweight who have sleep

apnea have more anxiety because they're

not getting rid of CO2 yeah so they're

literally suffocating in sleeping there

you'll see these people their mouth

breathers

not even necessarily just people who are

overweight so it's not good to be a

mouth breather

um you don't blow off enough CO2 anxiety

yeah you should sleep with like athletic

tape on your mouth so you train yourself

to breathe through your nose because

apparently it's way better for you yeah

I'll do cardio I do a long run once a

week or some long cardio I do with um I

try and not a mouth breed the whole time

can it also change face shape yeah so

this is a wild book called Jaws a hidden

epidemic by Collies of mine at Stanford

and they show they have these twin

studies one kid grows up in a culture

where they eat a lot of soft food

drinking Capri Sun eating applesauce

baby food the other one is you know got

stuck in the jungle or whatever it is

and they're chewing on Bones and chewing

their food and one kid these are

identical twins has beautiful jaw

structure and high cheekbones and the

eyes and look nice and clear the other

kid is like droopy the teeth are they in

their mouth breathing they show this

there's one case of this young girl who

just she got a pet or a pet hamster I

think it was got a a allergy to the

hamster and literally took beautiful

young girl and she just her face just

starts aging at a rapid rate they get

rid of the hamster she goes back to

nasal breathing they do a little

encouragement of nasal breathing using

the mouth closure thing at night do a

little bit of medical tape and like

create these beautiful almost like

model-esque features come back in this

girl jaw shape and the clear to the

nasal passages you know really there's

no reason why any of us should ever had

had braces but all your teeth should fit

in your mouth right and you should be

able to put your tongue on the roof of

your mouth

with your mouth closed I can't quite do

it your palate should be somewhat wide

you know and so when we see now there's

the jawser Sizer is really big in

Hollywood that and peptides are like

taking over Jaws or Sizer yeah these

like things were like bouncy mouthpiece

yeah it looks the only problem is it

makes people drool it's pretty gross but

you know it's work exercise they

definitely worth they change your facial

structure they dilate the the um uh the

nasal passages you look at somebody who

keeps their facial muscles strong

there's and this is for women and men

their jaw muscles strong we're not

talking about the like you know like I

mean there's certain people who are like

genetic freaks like my friend Laird

Hamilton he's got you know it's like big

old neck and like yeah John like he

looks like a you know an actor from the

70s or something he's just naturally

that way

um but people who care about their

facial structure especially who don't

want a lot of people are concerned or

like what's going on with my skin a lot

of

um women and men are like putting all

the stuff on and figure out how to get

rid of the droopy eyes it's actually a

facial muscle issue and where they just

to do some jaw exercises and focus on

not mouth breathing it completely

changes the structure of the face in

just two three months and there's yeah

there's like skin care salons called

like face gym and other places where

they're literally giving your face a

workout and you'll notice that it's like

a lymphatic type of massage it'll change

after one session so I imagine just

doing the training yeah so when girls

are getting like maybe this doesn't work

actually when girls are getting filler

to like put in like they have the hollow

space or whatever here or here does that

does that well I look at the plastic

surgery thing now and it's kind of crazy

I mean maybe this just reflects my age

and my generation but

I see some people with wearing so much

dark eye makeup plus they're getting the

cheekbone inserts they look like

skeletons now that's not yeah I really

listen everyone's got their taste

especially if they're really lean you

know and then but facial structure is

something that can be modified

um and so the having a chewing your food

chewing hard Foods is something we used

to do a lot more all this slurping down

of food and calories we know isn't good

from the Obesity side but it's also not

good from the Jaw structure teeth

structure face structure and it's all

related you know so that book Jaws is

amazing people can just look it up

online if they want to buy them but just

do um you know Jaws

um mouth structure face structure and

then just go images and you'll see these

pictures

and this was known in the 1800s there

was a book called shut your mouth by a

British Doctor Who talked about the fact

that people who snore

asleep like this and then during the

daytime they become mouth breathers he

said they become less attractive than

the people who are

um nose breathers yeah it's pretty

interesting yeah it's really interesting

and this is like a zero cost thing but

um it's not emphasized enough at all

yeah yeah I've heard this is crazy crazy

I mean I saw random things on like maybe

Tick Tock or Instagram of of uh people

who said yeah I started chewing this

thing or maybe it was a hard gum I

thought yeah yeah there's a hard gum

yeah and I was I thought that this was

some like uh I don't know just some Ploy

some like gimmick yeah to get some quick

money out of people but no this is legit

yeah yeah and there's a you know also

for avoiding orthodontia you know like

uh kids who chew hard food to have to

chew their food eating real food and

chewing their food not just peanut

butter you know slurping down food all

the time they using their jaw and their

teeth they have really nice teeth in

fact the argument was made and there's a

you know animals in the animal kingdom

have beautiful teeth structure you don't

see the the messed up teeth the

beautiful teeth structure and they don't

wear braces but they're tearing flesh

and they're doing their thing we brought

this up before you look at like

mummified people from like way back in

the day their teeth are always like

pretty good yeah and like they're not

they don't have all crazy they're not

eating sugar at the same rate stuff like

that but those are the elites bro you

know Olivia's got chewing on Bones and

things like that well and if people

think this sounds like kind of like

actually wait that makes sense they were

probably the ones eating the best food

the ones having to chew on meat because

it was the rich people that are going to

be able to get that meat because I don't

think they were mummifying everybody

right I mean like people like the bog

man that like is in you know England

that got frozen in like some boss oh

okay even he has yeah like their teeth

are not in the way the American teeth

are now so then why did why did humans

start losing their teeth there's like

the this nice structure you mean yeah

like you even look back at you know old

presidents and stuff like that like

George Washington and all fake teeth

like what did he start ingesting that's

getting rid of well I think back then

the problem was that you know there was

no I mean Dental Care is still a good

idea yeah in fact bacteria in the teeth

and not I'm terrible about floss maybe

sugar too sugar and also people not

flossing I mean flossing and you know

flossing into care actually improves

heart health this is not pseudoscience

yeah I've heard that because if you have

bacteria living in your mouth right and

starting to take residence in your mouth

and they get into your system it can

cause issues for the rest of your body I

mean we of course operate it as a whole

system

um you know I'm pretty bad about

flossing I was one of these kids had

tons of cavities it was just and I took

decent brush twice a day I don't know

are any of you three times a day

brushers

people they always impress me they're

brushing their teeth after lunch yeah

it's not me either

um you know flossing and brushing

definitely good to keep bacteria out but

it's amazing what you know chewing your

food really well yeah will do for a

facial structure
