The wet land aroma is rich for many people and this is not a coincidence, a scientific study discovered what is due.
He aroma that gives off the earth when the first drops of rain fall has a scientific name, the Petricor. This term was coined in 1964 by geologists Isabel Joy Bear and Richard Thomas to describe the characteristic smell that occurs when the rain impacts dry soils. According to studies published in the journal Naturethis phenomenon is due to the lIberion of chemical compounds Specific that are activated with moisture.
Petricor arises from the combination of two main elements. On the one hand, Plants release essential oils during drought periods. On the other, soil bacteria As actinomycetes produce geosmina, a volatile organic compound. When the rain falls on the dry earth, These elements volatilize and generate the aroma so distinctive that many people associate with freshness and renewal.

Why is the smell of rain so “rich”?
The preference for this aroma is not accidental. Neuroscience research suggests that petricor activates brain areas related to Memory and positive emotions. For our ancestors, The smell of rain meant the end of drought periods and the beginning of times of fertility in the fields. This evolutionary association endures in our subconscious, generating sensations of calm and well -being by perceiving this aroma.
The smell is particularly intense in arid areas after long periods without rainto. In these cases, the accumulation of compounds in the dry soil is abruptly released with the first rainfall, creating an explosion of aromas. This phenomenon explains why Petricor is more noticeable in desert regions than in areas with frequent rains, where the soil does not have time to accumulate these compounds.
