The Physiology of Scent During High-Intensity Exercise
During intense anaerobic and aerobic workouts, respiration rates increase from 12 breaths per minute to over 45 breaths per minute. Heavy, sweet, or synthetic fragrances can trigger bronchospasms, headaches, and nausea. Botanical aromatics rich in 1,8-cineole (eucalyptus) and menthol (peppermint) stimulate cooling sensory receptors, making heavy breathing feel effortless and crisp.
