## Why Not to Hold Your Breath When Scuba Diving
Holding your breath while scuba diving is a dangerous practice that can lead to serious injury or death. There are several reasons why you should never hold your breath while diving, including:
### 1. Lung Overexpansion
When you hold your breath, the air in your lungs expands as you descend. This is because the pressure of the water increases as you go deeper, and the air in your lungs compresses. If you hold your breath for too long, the air in your lungs can expand so much that it causes your lungs to rupture. This can be a fatal injury.
### 2. Nitrogen Narcosis
Nitrogen narcosis is a condition that can occur when you breathe compressed air at depths greater than 100 feet. Nitrogen narcosis causes a feeling of euphoria and drowsiness, which can impair your judgment and make you more likely to make mistakes. Holding your breath can increase your risk of nitrogen narcosis because it causes you to breathe in more nitrogen than you would if you were breathing normally.
### 3. Oxygen Toxicity
Oxygen toxicity is a condition that can occur when you breathe pure oxygen at depths greater than 60 feet. Oxygen toxicity causes a variety of symptoms, including seizures, nausea, and vomiting. Holding your breath can increase your risk of oxygen toxicity because it causes you to breathe in more oxygen than you would if you were breathing normally.
### 4. Carbon Dioxide Buildup
When you hold your breath, the carbon dioxide levels in your blood increase. Carbon dioxide is a waste product that is produced by your body’s cells. High levels of carbon dioxide can cause a variety of symptoms, including headaches, dizziness, and confusion. Holding your breath for too long can lead to carbon dioxide buildup, which can be fatal.
### 5. Hypoxia
Hypoxia is a condition that occurs when your body does not receive enough oxygen. Hypoxia can cause a variety of symptoms, including confusion, loss of consciousness, and seizures. Holding your breath can lead to hypoxia because it prevents your body from getting the oxygen it needs.
### 6. Drowning
Drowning is the most serious risk associated with holding your breath while scuba diving. If you hold your breath for too long, you will eventually lose consciousness and drown.
## Conclusion
Holding your breath while scuba diving is a dangerous practice that can lead to serious injury or death. There are several reasons why you should never hold your breath while diving, including lung overexpansion, nitrogen narcosis, oxygen toxicity, carbon dioxide buildup, hypoxia, and drowning. If you are ever tempted to hold your breath while diving, remember the risks and breathe normally instead.
