Today, a new study was published showing the effect of simultaneous artificial stimulation of the nasotrigeminal nerve and peripheral chemoreceptors on the strength of the diving response:
Repetitive paired stimulation of nasotrigeminal an...[Am J Physiol Regul Integr Comp Physiol. 2008] - PubMed Result There is a related older study demonstrating similar effect: ScienceDirect - Brain Research : Electrical stimulation of the anterior ethmoidal nerve produces the diving response Hmm, perhaps we soon start seeing freedivers with electrical wires hanging from their noses during competitions

Well, those studies claim that the key dive response nerves are in the nasal passages. That would explain why flooding your sinuses produces such a big dive response & extends the dive time. Maybe flooding your sinuses with something even more irritating than seawater would amplify the response?
If I immerse my face in cold water and let water up my nose, I can get instant contractions, even if I did a breathe-up before hand. However it only works on the 1st try of the day.

I usually have a stronger response through artificial stimulation.
What were we talking about again?

Well Benny, you had me instantly transfer my hot chocolate from the back of my throat back up to my nose. Maybe good jokes are the key to wed equalisation?
Perhaps that's why Tom Sietas didn't use any nose clip in his 10'12" world record static dive? I knew a former neighbour girl who used to compete statics with her brother and explained she breathed water, circulating it through the nose and mouth during her attempts. Her claim was she managed 7 minutes, her brother apparently 7'40". So this story triggers al sorts of idea's in my head... Let's try it! Love, Courage and Water, Kars

The hot chocolate was nice, as well as the joke, so no worries
They were of Indonesian origin. I should have invited her to a pool an learn her "water breathing" trick. My best static was while I was having a terrible itch in my throat inducing a constant swallowing reflex. Now if I couple this with the added DR stimulation of water in the nose, 8 minutes should be easy  Euhm well I get carried away...Let's not post here to much, our competitors might use the idea Love, Courage and Water, Kars
