Aroma Psychology(II)


      Aromatic psychology, as its name implies, is the effect that aroma has on the human mind through its sensory response. Some people ask, can only aroma have a psychological effect? No, rightly speaking, all smells can have an impact on a person's psychology, but there are only positive and negative effects. Stinky, disgusting smells are easy to cause bad associations, and thus produce negative emotions; while fresh and aromatic smells can make people associate beautifully, thus generating positive and positive emotions.

     Why does smell have such a different effect on human psychology? If you understand the relationship between smell and the brain, you will understand the principle.

      Each of us has five senses. Among them, in addition to olfactory information, the four senses of vision, hearing, touch, and taste are converted into radio wave signals after being sensed by the senses, and then first transmitted to the neocortex of the cerebral cortex.


       Neocortex is the most developed part of the human brain during evolution. It controls human instincts and is the area where the brain controls rationality. The neocortex is full of nerve cells, and memories are formed here, so people have cognitions such as "This is a red rose" and "That is her favorite matcha latte".


      This information is then transmitted to the ancient cortex of the limbic system of the brain. The limbic system of the brain is also known as the "animal brain", where animal instincts such as joy, sadness, anger, fear, like, dislike, anxiety, and unhappiness arise. Here, there will be cognition with personal emotions, such as "the scenery here is beautiful", "this song is romantic" and other subjective feelings.


      Only olfactory information is transmitted directly to the limbic system of the brain without going through the cerebral cortex. That is, emotions are directly mobilized without being filtered by reason and memory. Because of this, sense of smell is called human instinct animal sense.

Effects of aroma on psychology

      For example, when we are walking on the road, when the aroma of delicious food is suddenly fascinated, saliva will be secreted unconsciously in our mouth, and we may feel hungry. Then we will judge that it is the smell of barbecue.


      In this process, we first smell the scent, then the desire to eat appears, and finally make a cognitive judgment that "this flavor is the taste of barbecue". In other words, the sense of smell mobilizes people's emotions before visual perception, understanding and cognition.


      Delightful aromas can make people feel emotionally stable and comfortable. On the contrary, smelling unpleasant smells can affect emotions and make people upset. In daily life, we always encounter things that are wishful or unsatisfactory. When we feel depressed and sad, we strongly recommend that you use a pleasant fragrance to switch your mood and dispel negative energy, which will have psychological effects. Positive, optimistic, and positive impact.
