A healthy person inhales and exhales approximately 23,000 times a day. Among other things mixed with the air, our respiratory system also receives fragrances. The sense of smell allows us to interpret and read our environment. Published: 09-28-2022 Smells can also remind us of our past memories or even the positive or negative emotions related to them. Thus, fragrances accompany us throughout our lives . Whether they are the most beautiful or the least pleasant, they all affect our feelings, the comfort of living and even our day-to-day decisions . Why do we smell smells? Smell is the most sensitive human sense . It allows humans to receive odors that they can register even unconsciously. Odors can affect people's behavior, as well as their physical and mental state. This is mentioned in ancient Egyptian papyri and Hindu texts and in the Bible and the Koran. The numerous observations written about odors show how important their role has been over the years. Odors are perceived when breathing air that contains one or more fragrances. To detect an odor, its content in the air must be higher than its minimum concentration. Additionally, the chemical element or compound will give off a fragrance if it exhibits a specific volatility and high vapor pressure . It must also have the ability to penetrate the mucosa, our olfactory organ ('smell'), and to form special complexes linked to receptor proteins located in the membrane of the receptor cells of the epithelium.
These cells transmit information about the reception of a stimulus to the rhinencephalon and then to the higher structures of the central nervous system. So what is a smell? Smell (Latin : Olfactus) is the ability of elements, chemical compounds and their mixtures (odorants) to stimulate the organ of smell through stimuli that provoke specific behaviors. In other words, a smell is the sensory perception of an odor (an odor) that is registered in our brain as a result of the action of a chemical stimulus. We often identify the term 'aroma' with 'a pleasant fragrance' (of essential oils, for example) . However, 'aroma' can in some cases refer to an unpleasant or neutral aroma. In addition to the human ability to sense specific aromas, odors can have a therapeutic effect that CZ Leads promotes good health . The field of natural medicine that uses the therapeutic effect of plants is called aromatherapy . The key role here is played by essential oils , which contain active substances that originate from flowers, leaves, roots, seeds or bark . These oils are used in the form of inhalants or as preparations that are applied to the skin during a massage, added to water in a bath or used in other cosmetic treatments. How many olfactory stimuli can humans distinguish? According to scientists, humans can differentiate several million colors and almost half a million different shades, but the number of distinguishable odors has not been thoroughly tested . According to the available literature, humans can differentiate around 10,000 odors .
However, this has never been confirmed empirically. Together with a team of other scientists, C. Bushdid has carried out psychophysical tests aimed at determining the range and sensitivity of the human ability to smell. He tested people's ability to distinguish odor mixtures with different amounts of common ingredients. The results were spectacular, showing that people can distinguish at least 1 trillion odors, much more th CZ Leads an previous estimates. The bottom line is that the human olfactory system, with hundreds of different olfactory receptors, far surpasses other senses in the number of physically different stimuli that can be differentiated. What are essential oils and what do we use them for? Often known as " liquid gold ," essential oils are a group of chemical compounds that are the source of specific intense odors . These substances are used to manufacture various types of products, such as: perfumes, Eau de Toilette, deodorants; white and colored cosmetics; cosmetics classified as personal hygiene products; cosmetics and automobile accessories; air fresheners; detergents; scented candles; flavors and food products; pharmaceutical products; animal feed and products; agricultural preparations. Essential oils are aromatic mixtures of organic chemical compounds . They exist in the form of an oily, often colorless liquid .
