The golden rule in scuba diving is "Never hold your breath." This rule is fundamental to safe diving and prevents potentially dangerous situations.
Holding your breath while diving can lead to lung overexpansion injury, a serious condition that can cause damage to the lungs. This occurs when the air in your lungs expands as you ascend, due to decreasing pressure.
To avoid this, divers are taught to breathe continuously and exhale as they ascend. This allows the air in their lungs to escape gradually, preventing overexpansion.
The golden rule is not just a suggestion; it's a crucial safety measure that can save lives. Always remember to breathe normally and exhale as you ascend.
