You cannot survive underwater indefinitely if you are drowning. Once you lose consciousness, you will not be able to breathe, and your body will start to shut down.
Here's a breakdown of what happens when someone drowns:
* Initial Panic: The initial instinct is to struggle and gasp for air, but the body quickly becomes overwhelmed.
* Loss of Consciousness: As oxygen levels drop, the brain shuts down, leading to unconsciousness.
* Hypoxia: The lack of oxygen causes damage to the body's organs, including the brain.
* Cardiac Arrest: Without oxygen, the heart stops beating, leading to death.
The time it takes for these events to occur can vary based on factors like:
* Age: Children and elderly individuals are more vulnerable to drowning.
* Water Temperature: Cold water can shock the body and accelerate the drowning process.
* Health Conditions: Pre-existing health issues can increase the risk of drowning.
It's crucial to remember that drowning is a serious risk, and immediate action is needed to save someone who is struggling in the water. If you see someone in distress, call for help immediately and try to reach them safely if possible.
