NO was discovered in the 1970’ s in research that was awarded a Nobel Prize. It is a vasodilator, like a natural Viagra, actually exploiting the same pathways in the body. It is a gas that is produced in the Para nasal sinuses in very small quantities. In large quantities it is toxic. It is of extreme interest to freedivers, it improves breath hold and also protects the system being overcome by ROS (free radicals) during blood shift (ischemia and referfusion) during the Ischemic stage phase, where it behaves like a powerfull anti oxidant.

I have long speculated that diver exhaustion after a series of extreme deep dives might be due to NO depletion, or the 3rd day exhaustion factor. NO also behaves as an anti inflammatory and is helpful in preventing DCS in freedivers.

Erika agreed that this might be an exciting subject for research.
