  • By the age of 30, you'll have taken around 250 million breaths.
  • Chances are you've been doing it wrong.
  • Humans have become terrible at breathing.
  • This impacts anxiety,
  • your ability to focus, to sleep, how you feel -
  • almost every facet of your health.
  • The good news is, there are a few simple ways to breathe better
  • and live a healthier and happier life.
  • Here's how.
  • The nose isn't some random appendage,
  • it's a wonderfully complex organ.
  • The inside of it looks a lot like a seashell, which makes sense
  • because sea creatures use their shells to keep out invaders.
  • So do we.
  • Each breath you take in through your nose is filtered,
  • warmed and pressurised,
  • making it easier for you to absorb oxygen.
  • The cavities within the nose also release a miraculous molecule
  • called nitric oxide, which opens up blood vessels
  • and helps our bodies kill off viruses and bacteria.
  • A wondrous thing it is - the nose.
  • The problem is, up to half of us don't use it.
  • We breathe through our mouths.
  • Dust, pollutants, mould, viruses -
  • all this gunk goes directly into our bodies with no filter.
  • After a while, it can cause irritation
  • and an overgrowth of bacteria
  • that can give you cavities, bad breath, gum disease,
  • and make you much more susceptible to things like snoring
  • or allergies or asthma.
  • This is not good.
  • But how did it happen?
  • How did we become the worst breathers in the animal kingdom?
  • We'll need to go back a few million years to find out.
  • As we evolved from our ape-like ancestors, our brains grew,
  • shrinking the real estate in our mouths and sinus cavities.
  • If you look around today,
  • more than 90% of us have a chin that is recessed,
  • a mouth that's too narrow,
  • and the shrunken sinus cavities that come with it.
  • OK, I know this is getting pretty depressing,
  • but just know that your breath is not a foregone conclusion.
  • Make nasal breathing a habit.
  • The more you use your nose, the more the tissues will open up,
  • the easier it will be to become a full-time nasal breather.
  • Chewing pumps more blood to the brain,
  • drains fluid in our ears,
  • and most importantly, it helps us develop
  • a wide and forward-growing face.
  • Chewing when we are young makes it easier for us to breathe
  • when we get older.
  • You can also hum.
  • It might sound ridiculous,
  • but humming will increase nitric oxide in the sinuses 15-fold.
  • It can be anything.
  • Try humming your favourite song.
  • Many of us breath too much, too often,
  • taking in and exhaling a breath every three seconds or so.
  • But to operate at your full potential,
  • you should aim to lengthen this pace.
  • The ancients knew all about this.
  • Six seconds in.
  • And six seconds out.
  • But they didn't call it slow breathing.
  • They called it prayer.
  • Recent studies have shown that breathing like this
  • for just a few minutes a day can have huge benefits
  • to your mental and physical health.
  • You can try it.
  • In...two, three,
  • four, five, six.
  • And out...two, three,
  • four, five, six.
  • And in...two, three,
  • four, five, six.
  • And out...two, three,
  • four, five, six.
  • Make your breath like a circle,
  • seamlessly transitioning from inhale to exhale.
  • Whenever you feel stressed or want a little more calm or more oxygen
  • or just need to balance your nervous system,
  • slow that breath down.
  • You know, breathing well doesn't require wearing robes
  • or yoga pants or necklaces and crystals.
  • This is a biological function,
  • and you can do it wherever you are, whenever you want.
  • Let's make each of those breaths count.
