Was trying to reply to your comment, not happening so here’s what I’ve got for you….
Thanks for the follow up. Check out diaphragmatic breathing for divers.
And check these videos out:
a lot can be learned from Porpoises too 🙂
Hello Ruth Schrader-Grace,
Thank you for bringing this to my attention. It brings back the days of playful experimentation during my swimming and diving free time sessions. I like the sources Kimberly shares with us, also. Getting into a relaxed mode and breathing out slowly while making a sound always lets me stay sub surfaced longer. It came in handy to keep me from panicking when I was accidentally jumped on at the pool bottom.
