Humming can flood your sinuses with nitric oxide.
James Nestor is blunt about it. Nitric oxide helps the body deal with bacteria and viruses and it opens blood vessels. That is the same pathway erectile drugs use.
Nose breathing already gives you about six times more than mouth breathing. Humming, he says, multiplies it again, about fifteen-fold. So if your face is stuffed, or a cold is starting, he tells you to hum on purpose.
The move is simple. Keep the mouth closed. Inhale through the nose. On the exhale, hum a low note so the vibration sits in the face, not the throat. A song works. A single “mmm” works. A few minutes is enough. You should feel it in the cheeks and behind the nose.
There is no clean clinical trial. He says that. What he has is his own experience and hundreds of people who felt the pressure move.
Your sinuses already make the gas. The hum just shakes more of it into the air you inhale.
A Harvard neurologist told me:
“Sticking out your tongue for 40 seconds removes cortisol faster than any pills and breathing exercises.”

hi, i'm sophia 👩💻 I've done over a billion views for brands like Netflix, Lovable, and Uber
this is exactly how top tech startups are finding viral UGC formats faster than you
We’ve officially hit the point where AI UGC is cheaper AND better than real UGC.
This video is 100% AI and cost under $1. (And no, it’s not Sora, Veo, or Kling).
My system is built for mass-scale organic across thousands of accounts. Here is why it wins:
- Hyper-realistic visuals: Natural physics and movement look flawless.
- Insane cost efficiency: Costs pennies compared to traditional UGC programs.
-Consistent audio: High-quality, rock-solid voiceover throughout.
- Infinite scaling: Videos can run to any length cost-effectively.
This changes everything.

“3 viral slideshow hooks” — 2.9m, 930.8k, and 90.2k views across just three slideshow formats, one creator and have made £4,000+
the hooks that are actually working right now:
→ “signs of bad [health thing]” — numbered list format, listicle hooks convert because people wait for the number that applies to them
→ relatable cartoon/meme format — “it’s nearly summer but i have acne” — humor + relatability pulls way higher engagement than a straight product pitch
→ before/after body shot — visual proof does the hook’s job without a single word of text
notice none of these are complicated. no fancy editing, no talking, just a strong first slide that makes someone stop
the accounts getting millions of views on slideshows aren’t reinventing the format every time, they’re running the same 2-3 proven hooks on repeat with new content inside them
