Researchers have discovered a fundamental mechanism that affects the size of the pupil, namely our breathing. The study shows that the pupil is smallest during inhalation and largest during exhalation ...

Scientific literature provides evidence that the way we breathe influences neural areas related to attention, memory, smell, ...

New research suggests that the natural rhythm of breathing plays an important role in organizing the brain activity required for human memory. The study indicates that successful memory retrieval is ...

For over a century, scientists believed that light, focus distance, and cognitive effort were the main forces behind changes in pupil size. But a new discovery adds breathing to that list. Researchers ...

For more than a century, scientists have understood that three factors control pupil size: light, focus distance, and ...

Researchers at Karolinska Institutet in Sweden have discovered a fundamental mechanism that affects the size of the pupil, namely our breathing. The study, published in The Journal of Physiology, ...

Two years ago, I published a nine-part series, "The Vagus Nerve Survival Guide to Combat Fight-or-Flight Urges." The genesis came from an "Aha!" moment when I noticed a pattern of diverse scientific ...

Accessory muscle breathing means using muscles other than those typically used for breathing to take in and expel air. One example is the subclavius — between the collarbone and the top rib — which ...

Breathing comes naturally and easily when our lungs are healthy. However, shortness of breath and difficulty breathing are among the symptoms of COVID-19 that can linger for some patients after ...
