To the point where we hold our breath underwater How can we be so successful? On the contrary, wouldn’t it be better to do this outside of water?

Bride, answers to these questions Let’s give it.

In fact, this ability can be explained by a strange phenomenon.

This situation, known as the mammalian diving reflex or mammalian diving response, is the response that humans and other mammals experience when diving into water. It is a series of automatic and physiological changes.

When people dive into water, the signals are transmitted by the trigeminal nerve Sensory information is activated. When this response is triggered, we automatically stop breathing. The heart rate slows and vascular resistance increases.

In addition, the body suffers from increased vascular resistance and damage to vital organs, including the brain and heart. while preserving oxygen supplies, It can draw blood away from inactive muscle groups.

On the other hand, during breath holding, the carbon dioxide level in the blood increases and the oxygen level decreases.

The desire to breathe underwater is due to the increased carbon dioxide. As carbon dioxide increases, oxygen levels decrease and So the desire to breathe increases.

This desire gradually increases and eventually this need is replaced by the primary respiratory muscle. intensifies to the point where the diaphragm contracts involuntarily. Then involuntary breathing takes place.

Furthermore, when pure oxygen is pre-breathed, the breathing reflex may be delayed and this allows people to stay underwater for up to 20 minutes.
