Both of those worries are not risks. Since you're breathing air at only one atmosphere of pressure, no matter how deeply you dive, upon your depressurization as you approach (hopefully!!!) and reach the surface, there is no gas in solution that wasn't already in solution when you took that breath. Therefore no "bends" or decompression sickness. As for nitrogen narcosis, the same reasoning applies, you are only taking one lungful of nitrogen laden air, something you've done countless thousands of times already. It isn't possible to saturate yourself with nitrogen starting with sea level air pressure and ending with sea level air pressure.

Dangers? Sure. Hyperventilation is a big one. That's when you essentially blow off the carbon dioxide to below the normal level during normal respiration. It's the presence of CO2 that gives you the urge to take a breath. By artificially changing that level, you "trick" your body into thinking you don't need to take a breath. Yeah, these folks are nutzo.
