¿Cómo aguantamos la respiración?

The video explains the immersion reflex, which stops breathing when the face contacts cold water to conserve oxygen. It describes how the body produces more red blood cells to absorb oxygen and how training can help override this reflex, allowing humans to hold their breath longer, similar to animals like otters and dolphins.

What triggers the immersion reflex in the human body?

• Contact with cold water

• Intense physical exercise

• Exposure to warm air

• High altitude

What is one of the body's responses to the immersion reflex?

• Decrease in lung capacity

• Increase in red blood cell production

• Decrease in red blood cell production

• Increase in heart rate

How can training affect the immersion reflex?

• It has no effect on the reflex

• It can help manage the reflex

• It can eliminate the reflex

• It can enhance the reflex

What breathing technique can help expand the lungs?

• Breathing through the nose

• Breathing through pursed lips

• Holding the breath
