Controlled breathing like this can combat anxiety, panic attacks and depression. It’s one reason so many people experience tranquility after meditation or a pranayama yoga class. How exactly the brain associates slow breathing with calmness and quick breathing with nervousness, though, has been a mystery. Now, researchers say they’ve found the link, at least in mice.

The key is a smattering of about 175 neurons in a part of the brain the researchers call the breathing pacemaker, which is a cluster of nearly 3,000 neurons that sit in the brainstem and control autonomic breathing. Through their research is in mice, the researchers found that those 175 neurons are the communication highway between the breathing pacemaker and the part of the brain responsible for attention, arousal and panic. So breathing rate could directly affect feeling calm or anxious, and vice versa.

If that mouse pathway works the same way in humans, it would explain why we get so chilled out after slowing down our breathing. READ MORE
