This study from the Icahn School of Medicine examined breathing patterns in 57 chronic fatigue syndrome patients compared to 25 healthy controls during cardiopulmonary exercise testing. The researchers discovered that 71% of chronic fatigue patients experienced breathing problems—either hyperventilation, dysfunctional breathing, or both—compared to minimal breathing issues in the control group. Nearly half of the chronic fatigue participants displayed erratic breathing patterns, and about a third hyperventilated during the tests, with some experiencing both conditions simultaneously. The scientists suggest these breathing abnormalities, possibly triggered by dysautonomia (abnormal nervous system control), may be worsening chronic fatigue symptoms or contributing to post-exertional malaise. The findings point toward potential new treatments including breathing exercises through yoga, gentle physical conditioning like swimming, or biofeedback techniques to help patients manage their symptoms.
