## How to Breathe Underwater While Scuba Diving
Scuba diving is an exhilarating experience that allows you to explore the underwater world firsthand. However, before you can dive, you need to learn how to breathe underwater.
### How does scuba diving work?
Scuba diving uses compressed air to allow you to breathe underwater. The air is stored in tanks that you carry on your back. When you dive, you breathe the air from the tanks through a regulator, which reduces the pressure of the air to a level that you can breathe safely.
### How to breathe underwater
1. Inhale through your mouth. When you inhale, the air from the tank flows into your lungs through your mouth.
2. Exhale through your nose. When you exhale, the air from your lungs flows out through your nose.
3. Repeat. Continue inhaling and exhaling through your mouth and nose until you reach the surface.
### Tips for breathing underwater
Relax. It’s important to relax when you’re breathing underwater. If you’re紧张, you’ll use more air and you’ll be more likely to run out of air.
Breathe slowly and deeply. Don’t try to breathe too quickly or too deeply. This will also use more air and make you more likely to run out of air.
Use your diaphragm. When you breathe, use your diaphragm to push air into and out of your lungs. This will help you breathe more efficiently.
Clear your ears. As you descend underwater, the pressure on your ears will increase. This can cause your ears to pop or hurt. To clear your ears, simply pinch your nose and blow gently.
Don’t hold your breath. Holding your breath can cause you to black out. If you need to hold your breath for any reason, such as to equalize your ears, do so for only a few seconds.
### What to do if you run out of air
If you run out of air underwater, don’t panic. Here’s what to do:
1. Signal to your buddy. If you’re diving with a buddy, signal to them that you’re out of air. They should give you their spare air.
2. Ascend slowly. If you’re not diving with a buddy, you’ll need to ascend slowly to the surface. As you ascend, the pressure on your lungs will decrease and you’ll be able to breathe again.
3. Don’t hold your breath. Holding your breath can cause you to black out. If you need to hold your breath for any reason, such as to equalize your ears, do so for only a few seconds.
