## How to Not Use Air During Scuba Diving

Scuba diving is an amazing way to explore the underwater world, but it can also be dangerous if you don’t know how to breathe properly. One of the most important things to remember is to never hold your breath while diving.

Why You Shouldn’t Hold Your Breath

When you hold your breath, the air in your lungs expands as the pressure around you decreases. This can cause your lungs to rupture, which can be fatal. Even if your lungs don’t rupture, holding your breath can still cause other problems, such as:

Nitrogen narcosis: This is a condition that occurs when nitrogen gas builds up in your bloodstream. It can cause confusion, disorientation, and even unconsciousness.
Oxygen toxicity: This is a condition that occurs when you breathe in too much oxygen. It can cause seizures, tremors, and even death.
DCS (decompression sickness): This is a condition that occurs when nitrogen gas bubbles form in your tissues. It can cause pain, numbness, and even paralysis.

How to Breathe Properly

To breathe properly while scuba diving, you need to:

Inhale slowly and deeply. Don’t take short, shallow breaths.
Exhale slowly and completely. Don’t hold your breath.
Breathe through your mouth. Don’t breathe through your nose.
Use a regulator. A regulator is a device that controls the flow of air to your lungs.

If You Run Out of Air

If you run out of air while diving, the most important thing to do is to stay calm. Don’t panic and try to hold your breath. Instead, do the following:

Ascend slowly. If you ascend too quickly, the nitrogen gas in your bloodstream can form bubbles, which can cause DCS.
Share air with a buddy. If you’re diving with a buddy, you can share air from their tank.
Use an emergency ascent device. An emergency ascent device is a device that allows you to ascend to the surface without using any air.


Scuba diving is a safe and enjoyable activity, but it’s important to know how to breathe properly. By following these tips, you can help avoid problems and enjoy your dives.

## Additional Tips

Practice breathing properly before you dive. The best way to learn how to breathe properly is to practice in a pool or shallow water.
Be aware of your breathing. Pay attention to how you’re breathing and make adjustments as needed.
Take breaks. If you start to feel tired or short of breath, take a break and rest.
Dive with a buddy. Diving with a buddy can help you stay safe and ensure that you have air to share in case of an emergency.
Get certified. Taking a scuba diving course is the best way to learn how to dive safely.
