If widely adopted, consumers may reduce antiseptic mouthwash usage post-exercise, potentially decreasing demand for these products. However, impact is likely limited as most consumers use mouthwash for oral hygiene rather than post-workout routines. Could shift purchasing toward gentler, non-antibacterial alternatives.
Potential regulatory scrutiny of antiseptic mouthwash labeling and health claims. Health authorities may need to issue guidance on optimal timing for mouthwash use relative to exercise. Could prompt research funding into oral microbiome's role in cardiovascular health.
