What happens if you cough or sneeze while scuba diving? 

First of all, let’s answer what happens if you need to cough or sneeze when you’re several meters into a deep-water dive. If you need to cough when scuba diving, you need to make sure that the regulator is in your mouth as you cough. If you cough with the regulator in your mouth, you’re going to be okay.

If you need to sneeze, again make sure your regulator is in place correctly and that you hold on to your mask to ensure no ‘shifting’ that could allow water to seep in.

There was a time when this news made front-page headlines all over the world, and for good reason-it’s something that nobody would wish on anyone. It seems like a scene from a bad horror movie, but it happened.

In 2009 an experienced German diver was exploring a shipwreck off of Mallorca Island, Spain. What happened next has been described as one of the scariest things that could happen underwater: The woman started coughing uncontrollably and her regulator blew out of her mouth.

Her husband managed to find it and put it back in her mouth, but by this point, she had swallowed a fair amount of seawater. What happens if you cough while scuba diving?

She quickly became disoriented and her regulator was pulled from her mouth again-this time for good.

Realizing that his wife was drowning, the man did what anyone would-he ditched his own regulator and attempted to give her his so he could go get help.

But within seconds they were both without a breathable supply of oxygen, and who knows how long it took them to succumb to the fatal effects of drowning.

What makes this story even more tragic is that it wasn’t a huge accident-it was a simple cough, but it did enough damage to kill two experienced divers.

What you need to remember is that in order to cough, your body just opens up your throat and allows all of the pressurized air in your lungs to come rushing out. What happens when you do this while scuba diving? Well, pretty much what you’d expect would happen – you have a great deal of trouble staying at depth.

 

What happens if you sneeze when scuba diving?

For any scuba diver who has ever had an uncontrolled sneeze or cough during their dive, they know exactly how uncomfortable it is.

Let’s think about why we have involuntary reactions like sneezes and yawns. These are meant to clear our nasal passages of irritants (or energy). What happens if you yawn while scuba diving? What happens is that your body opens up your lungs and throat even more. What you need to remember is that this will result in an uncontrolled release of all the pressurized air in your lungs, which may cause you to drop several meters into the depths of the sea if you’re too close to the surface already.

It’s not just coughing that can be dangerous during a dive; things like sneezing or hiccuping pose risks as well.

 

What happens if I hiccup while scuba diving?

All these actions will cause your body to open up even further, releasing everything inside of your lungs until there’s no pressure left at all. What you need to remember is that the air in your lungs is at very high pressure, and releasing it all of a sudden can cause damage to your lungs or even leave them collapsed. What happens if you sneeze when scuba diving? What might be worse than just having your body empty out your lungs of air during the dive is if you get water down there instead.

What’s really bad about this situation is that it could mean popping one of your eardrums (if not both); it will certainly mean ruptured eardrums or other injuries related to intense internal pressure changes in close quarters with water.
