SaralnamaPetrichor, the earthy scent of rain, contributes to our well-being across India. This fragrance comes from geosmin, a molecule made by Streptomyces bacteria when rain hits dry soil. Petrichor triggers a serotonin rush, improving mood instantly. Arpita Kohli, Psychologist at Delhi's Psri Hospital, says rain sounds reduce stress and aid sleep. The scent promotes relaxation, eases anxiety, and fights mental fatigue. Negative ions in post-rain air may boost brain serotonin, linked to happiness. While not used in standard aromatherapy, petrichor's calming effects align with its goals. Researchers suggest simulating earthy scents for stress reduction. Future studies may lead to new natural mood-enhancing treatments using petrichor. (Updated 27 Sep 2025, 21:05 IST; source: link)
