The smell of mud, often referred to as "petrichor," is a distinct earthy and pleasant scent that arises when rain falls on dry soil. This natural fragrance is caused by a combination of compounds released by soil-dwelling bacteria, organic matter, and oils. The phenomenon is particularly noticeable in regions where the soil contains certain types of bacteria or plant oils. Many people find the smell of mud after rain to be refreshing and nostalgic.

The term "petrichor" has its origins in Ancient Greek, deriving from the words petra (meaning stone) and ichor, a term used to refer to the blood of the gods in Greek mythology. However, contrary to this explanation, the scent we experience is not that of divine blood.
