Why Smell Is a Powerful Tool

Smell is one of the oldest and most primitive human senses. The olfactory system begins functioning in utero. As a person develops, olfactory stimulants influence their mental state and behavior.

The power of smell

When a person smells something pleasant, the information goes directly to the part of the brain responsible for emotions. The brain then communicates, "I'm glad to be here." But it's not just emotions that make scent a powerful tool. It's also the memories that are closely linked to emotions.

Unexpected flashes

Have you ever sprayed on perfume and experienced a sudden flashback, followed by a feeling you associate with the memory? This is an example of the powerful influence scent can have on our brains. Human olfactory receptors are directly connected to the area of ​​the brain responsible for memory and emotions. This explains such sudden flashbacks.

The Proust Effect

Over a century ago, Marcel Proust wrote about the integration of scent with emotion and memory. The taste and smell of a biscuit dipped in tea re-triggered and revived moments from a forgotten childhood. Hence the name " Proust effect ."

Nobel Prize for research on smell

The science of smell is an active and fascinating field. Contemporary interest in this field gained momentum in 2004. That year, Richard Axel and Linda Buck received the Nobel Prize in Physiology or Medicine for their groundbreaking work on the sense of smell. They studied olfactory receptors and the olfactory system . They discovered how the olfactory epithelium and olfactory bulb in the human nose function. They observed how the human brain recognizes and remembers approximately 10,000 different odors.

Scientific facts

As early as 1989, Susan Knasko noted that ambient scent influences how long customers stay in a jewelry store. Another researcher, neurologist and psychiatrist Dr. Alan R. Hirsch, used scent in an experiment at a Las Vegas casino. He scented two rows of slot machines, while leaving one row neutral. Hirsch observed that players were more likely to reach for coins in areas saturated with pleasant scents than in areas without them.
