Story summary

Researchers at Sweden's Karolinska Institute have unveiled a fascinating connection between pupil size and breathing patterns. As we exhale, our pupils expand, and they contract with each inhale, influencing our vision. This rhythmic response could be pivotal in diagnosing neurological conditions such as Parkinson's disease, paving the way for future studies on how breathing techniques might boost cognitive function and visual sharpness.
