Aromacology confirms: smells affect human health
Our life is filled with different flavors. Many people notice how their condition changes depending on the surrounding odors.

Why this happens and how exactly aromas affect a person's well-being is studied by the science of aromachology.

This drink has both pros and cons. But what do scientists think?
The science of scent
Aromacology is a fairly young science: scientists began to study the effect of odors on the emotional and physical state of a person only in the 1980s. This process was scientifically substantiated in 2004, when American biologists Linda Buck and Richard Axel discovered the mechanism of human recognition of aromas. In addition, neuroscientists have shown that the perception of smell is directly related to the emotions experienced.
Since then, the beauty industry has become interested in aromacology, because a functional approach to the choice of fragrances can enhance the effect of products.
Why do certain scents affect human health?
Essential oils used even before our era: they were burned to fumigate a room, they were added to solutions for embalming. However, aromatherapy does not provide specific descriptions of the effects of aroma oils, and they are not based on scientific research. For example, lavender oil is believed to have a relaxing effect. While the effects of juniper oil can range from soothing to stimulating brain activity.
According to one of the scientific theories about how different aromas affect the human condition, the molecules of the substance enter the bloodstream through the mucous membrane in the nose, and then spread throughout the body. This is proved by experiments on animals: in the framework of the experiment, molecules of inhaled oils were found in the blood of rodents.

Russian scientists within the framework of the project Influence of the odor environment on the physiological status and cognitive processes of a person proved that the smells of lavender and mint improve memory among schoolchildren aged 10-11 years. In addition, staff at the University of Hong Kong have also found that aromatherapy can help with depression.
Many scents are also believed to satisfy hunger. That is, they just muffle this feeling. FROMAmong them are aromas of rose, vanilla, grapefruit and mint.
How are the research results used?
Research in the field of aromachology is most in demand in the cosmetic industry. For example, some companies independently conduct experiments in this area. The concept is to enhance the effect of cosmetics with the right perfume.
In 2010, the Firmenich perfume company, together with the University of Geneva, conducted research on the effects of fragrances on the body. Based on the data obtained, fragrances for the company's creams and lotions were created. This is how products with herbaceous, woody aromas with a calming effect appeared.
