## Can You Cough While Scuba Diving?

Coughing is a natural reflex that helps to clear the airways of irritants. However, coughing while scuba diving can be dangerous, as it can cause you to lose control of your breathing and potentially lead to a drowning incident.

### Why is it dangerous to cough while scuba diving?

When you cough, you expel air from your lungs through your mouth and nose. This can cause you to lose buoyancy, which can lead to you ascending too quickly. Ascending too quickly can cause decompression sickness, which is a serious medical condition that can cause pain, paralysis, and even death.

In addition, coughing can cause you to aspirate water into your lungs. Aspiration can lead to pneumonia, which is a serious infection that can be life-threatening.

### What should you do if you need to cough while scuba diving?

If you need to cough while scuba diving, it is important to do so carefully. Here are some tips:

Try to hold your cough. If you can, try to hold your cough until you can reach a shallower depth. This will help to reduce the risk of losing buoyancy and ascending too quickly.
If you cannot hold your cough, cough into your regulator. This will help to prevent water from entering your lungs.
Be aware of your surroundings. Make sure that you are not near any other divers or objects that could be damaged by your cough.
Signal to your buddy that you need to cough. Your buddy can help you to stay safe by monitoring your ascent and providing assistance if needed.
