(upbeat music) – Hey there, this is Brain Stuff, and I’m Josh Clark, and
this is the Brain Stuff where I explain to you
what morning breath is. Pretty much all bad breath and all odors from all humans come from a
couple of different things, eating and being sick. Some of the foods we eat
are actually pungent enough to make it through
digestion and be absorbed into the bloodstream
and then into the lungs, and ultimately exhaled. Think of onions and garlic. But there’s one thing that
can give you bad breath, systemic conditions like diabetes or a lower respiratory tract infection can also give you bad breath, and particles of food
that get trapped between your gums and your teeth can give you pretty bad breath as well. At the root of all this,
though, is bacteria. Whether it’s from breaking
down food in our guts or breaking down food
particles in our teeth, or warding off an infection, bacteria can create
really, really big smells. As bacteria go to work
breaking down proteins, amino acids, and all biological material that they ferment as food, they produce waste products called Volatile Sulfur Compounds, or VSCs. VSCs are composed of things
like hydrogen sulfide, methyl mercaptan, and dimethyl sulfide, all of which pack terrible smells. And when they combine together into a super smell, stand back. But why is all this so
much worse in the morning? Which is to say, what’s the
deal with morning breath? The answer, it turns out, is dry mouth. When you sleep, you
produce much less saliva than you do normally,
like when you’re awake, and saliva combats bad breath two ways. One, it simply washes away food particles giving bacteria less food
to eat and break down and turn smelly, and also, using oxygen, it combats the number of
bacteria present in your mouth. Both of those things together
create a one-two punch that keeps you from smelling all the time. When it’s dry, though,
these particles hang around and give you terrible,
terrible morning breath. Now, don’t be alarmed,
morning breath is normal, but there are some measures you can take to mellow out your morning breath. For example, you can brush
and floss like a normal human being before going to bed. You can also just drink a
glass of water before bedtime. It’ll help wash out
any nastiness in there. And, would it kill to brush
your teeth first thing in the morning? I don’t think so. So, tell us, do you get
terrible morning breath? Is it worse than average? Let us know in the comments below, and don’t forget to

  1. What does bacteria and a lack of saliva have to do with it? Josh explains why we wake up with #badbreath  and what can be done about it in this @BrainStuff – HowStuffWorks episode.

  2. Every morning we wake up with bad breath. What does bacteria and a lack of saliva have to do with it?

  3. I get this very bad, including an awful taste meaning I must brush my teeth immediately when I get out of bed. Maybe I'll try drinking water before bed, but I don't like getting up to go to the toilet.

  4. This guy kinda reminds me of Dr. Steve Brule from Tim and Eric. Not that he's bad or anything, I just think it's kinda funny.

  5. I don't understand this guys shtick. It's like he's pretending to be slow or something. "I'm adorably befuddled and yet I'm still giving you the facts." Just talk normal man.

  6. I like this guy. He seems so normal in an almost boring way, yet he's so funny. I don't get it. It's like, hey, there's a guy walking down the street in khaki pants and a polo shirt. Damn that's funny!

  7. Also if u go to a dentist and tell them you have bad breath all the time even after brushing and flossing, those morons will stare at you blankly. They'll never even bother to take a look at tour tonsils and try to see if you might have tonsil stones which smell putrid and might just be hanging out in the back of your throat. Which might also be another reason for bad breath along with dry mouth

  8. Many thanks, I have been researching "how to get rid of horrible bad breath" for a while now, and I think this has helped. Ever heard of – Honulian Wiffy Remover – (Have a quick look on google cant remember the place now ) ? Ive heard some great things about it and my partner got great success with it.
