Скачать или смотреть Over-Breathing and Stress: The Science

One study showed that when participants hyperventilated and dropped their CO₂ levels by 50%, their adrenaline levels shot up by 360%.

Why?
Because low CO₂ triggers stress in the body, even if you're just sitting still or feeling anxious. When you breathe too much (especially through the mouth), you:

Dry out and irritate your airways.
Let in cold, unfiltered air filled with bacteria and particles.
Trigger inflammation.
And force your body to release adrenaline to open your airways back up.

Your body sees this as a survival issue, because oxygen delivery is at stake. That’s why mouth breathing and chronic over-breathing can lead to constant stress, even when you’re doing nothing at all.

This is also why adrenaline (epinephrine) shots are used in emergencies to force airways open. But what if your everyday breathing is doing the opposite?

Your breath is powerful. Use it wisely.
