The Secrets of Extreme Breath Holding

The video explains how humans need oxygen to survive and introduces the concept of breath holding. It warns against trying dangerous techniques and describes how elite breath holders hack three survival systems: the fight or flight response, the mammalian dive reflex, and diaphragm spasms. These techniques allow them to hold their breath for extended periods by staying calm, using the dive reflex, and ignoring diaphragm spasms. The world's best breath holders can hold their breath for over 11 minutes.

Why do humans need to regularly intake oxygen?

• To maintain body temperature

• To survive and support bodily functions

• To produce energy from sunlight

• To digest food

What is the primary effect of the fight or flight response on the body during breath holding?

• It decreases blood pressure

• It increases heart rate and oxygen consumption

• It enhances lung capacity

How do breath holders take advantage of the mammalian dive reflex?

• By holding their breath on dry land

• By submerging their face in water

• By breathing rapidly before diving

• By increasing their heart rate

What happens when the diaphragm starts to spasm?

• It prompts the lungs to get more oxygen

• It signals the body to relax

• It causes the lungs to expand

• It increases blood flow to the limbs

How many diaphragm spasms can the world's best breath holder withstand?

• More than 50

• More than 75
