Perfume in the Human Mind

Since birth, scents have impacted our lives more than we imagine. Have you ever felt transported back to childhood by the smell of hot chocolate that reminds you of cold winters at home? Or that scent that evokes the sea breeze? Even the smell of wet grass after a storm, which generates peace, calm, and a desire to breathe deeply until your lungs are full.

Our most prehistoric and visceral sense is also the one we think we use the least. And then it hits us in the brain when we least expect it.

It is the most sensitive sense we have, as the brain connection happens immediately.

This process works through the brain's own neurochemistry, triggered by perceived odors, and also influences cognitive aspects such as perception, identification, or cultural associations. The latter can exert a powerful influence on an individual's emotional reactions, making it of special interest. Scents identify countries, places, people, and even religions.

Although unconsciously, people make value judgments based on the scent a person emits. For example, striking up a conversation with someone whose smell we dislike creates a negative predisposition and vice versa.

What is perfume psychology?

Perfume psychology refers to the ability of certain aromas to evoke different sensations and memories, and also to modify our behavior based on them.

A scent is made up of tiny aromatic molecules. When you inhale an aroma through your nose, these molecules travel up the tiny olfactory nerves inside the nose and go directly to the brain's limbic system.

The limbic system is a network of structures that controls certain behaviors essential for the survival of all mammals, such as finding food and staying alive.

In addition, the amygdala (an organ of the limbic system) connects aromas with an emotion, and the hippocampus relates aromas with a memory. Hence, the evocative capacity of smells, which take us back to past moments and generate uncontrollable vegetative responses in our organism.

It has three essential functions: emotions, memories, and arousal (stimulus), which it translates from the information it receives from the external environment.

Therefore, the limbic system links memories with emotions and aromas, making scents remind us of specific situations, places, or people.

Likewise, there are also certain aromas capable of mentally calming us, and/or helping us ward off anxiety and improve our focus in the present.

Why do we like perfumes?

The right choice of perfume and its consistent use leads to emotional well-being and, therefore, a greater capacity to be decisive in life, alleviating stress and anxiety.

Furthermore, it is known to improve mood and make people more prone to positivity, and it enhances relationships with others because it boosts self-esteem.

Moreover, it cannot be overlooked that wearing perfume makes you more desirable: Some fragrances act as pheromones, making the wearer perceived as a more attractive person to others.

Likewise, the intensity and duration of fragrances allow us to stay in contact with our closest people, who inevitably associate our fragrance with us.

Often, we don't give it importance and only value it when we lose it, like when our nose is blocked: then, food tastes bland and the outside world seems very distant to us.

Once we recover it, we regain our appetite and feel more positive and energized.

Neuroscience of Smell

Some of the research findings on the neurological responses to smell are as follows:

• Brain waves: the aroma of jasmine increases beta waves, which are more frequently present in states of concentration or high emotionality; while the aroma of sandalwood and pine increases the generation of alpha waves, which is the dominant brain frequency in states of relaxation.
• Blood pressure lowers with the aroma of neroli.
• Micro-vibration is a fine tremor observed in warm-blooded animals influenced by muscle tension. This indicator decreased with the aromas of orange and lavender. The aromas of jasmine, chamomile, and musk increased micro-vibration and, with it, muscle tension.
• Peripheral vasoconstriction, associated with psychological stress. Jasmine and pepper have relaxing effects.
• Heart rate: the deceleration of heart rate is favored by sweet aromas, especially rose. With the aroma of lemon, it slows down due to increased concentration in response to an alert stimulus; the mind anticipates.
• Responsiveness: jasmine reduces reaction time to a decision while lavender increases it.
• Learning tests: aromas that were pleasant to participants increased memorization capacity. These were lemon, eucalyptus, and lily. It was also found that lavender, rose, and orange increase mental relaxation, while jasmine, chamomile, and musk stimulate the mind.
• Other tests showed that the aroma of heliotrope reduces stress and anxiety.
  
  

Smell from the beginning of time

Since prehistoric times, smell has accompanied us and helped us identify food, predators, and mates.

Just as then, smell continues to be one of the most important ways the environment communicates with us.

The sense of smell is, without a doubt, our greatest ally in facing the world around us. It helps us interact with our environment. Smells alert us, make us flee or attack, connect us with moments from our past, and make us relive feelings and emotions. When we are born, the first thing we do is follow the trail of breast milk. And, thanks to it, we are able to relax just by smelling our mother.

Smell is a sense intrinsically linked to the instinct of survival.

As humans became more sophisticated, they began to use scent to manipulate the body and heal themselves. Many ancient civilizations, such as Egypt, China, and India, used aromatherapy to treat many types of ailments, including headaches, pain, insomnia, eczema, stress-induced anxiety, depression, and digestive problems.

Conclusion

There are many reasons why we love using fragrances, and all of them are related to a powerful motive: Undoubtedly, aromas evoke many sensations associated with emotional well-being and happiness.

Furthermore, they make each person unique, as each fragrance is distinct: They identify us, give us personality, and make us stand out wherever we are.

For these reasons, perfumes have become so popular worldwide and have become synonymous with elegance, freshness, and class.

Once we find our perfect fragrance, we should not hesitate to use it whenever we need to feel more self-assured. Psychology recommends wearing our favorite scents just before giving an important presentation or going on a date.
