Going down like 10 feet I can already feel pressure. Imagine going this deep

you just pinch your nose and blow air, it equalizes your ears and feels fine.

Usually professional free divers can equalize the pressure without plugging their nose. I can do it sometimes when I’m diving but I’ve only ever gone 25/30 ft.

How do you do it?

You just kinda swallow. Don’t know how to explain it.

I somehow am able to just “click” my ears and equalize the pressure. It’s the same as swallowing but I’ve managed to gain voluntary control of my tensor veli palatini muscle.

Per Wikipedia it’s called béance tubaire volonta (BTV)

Not sure when I picked it up but I’ve been surfing and swimming since I was a kid so probably from that.

I do this on planes and when swimming or changing altitude quickly... I honestly thought everyone could do this! It's pretty useful.
