Smells and their effect on humans. When smells can be deadly

Aroma, pronouncing this word, one determines something pleasant in olfactory perception. The component to the epithet is expressed in addition to the emotional characteristic that has a positive effect on the subconscious. Pleasant associations are always associated with safety, for example, the smell of freshly baked bread makes you imagine a ruddy crust, and stimulates appetite.

There is no exact distribution of odors by aromaticity. The assessment is subjective, depends on the human factor, on the saturation, the concentration of the aroma. There are smells that, with strong saturation, give an unpleasant background, and with minimal use, they enchant with sophistication.

MOSCOW, April 15 - RIA Novosti, Tatyana Pichugina. Aromatherapy is not included in the arsenal of modern medicine, its destiny is beauty salons, massage rooms. Nevertheless, scientists are trying to understand how smell affects behavior, mood, human physiology. RIA Novosti talks about what the science of aromas has managed to achieve.

Psychologists of the Stavropol region began to use aromatherapy in their work in the colonyIn the women's correctional colony No. 7 in the Stavropol Territory, specialists help women relieve emotional stress with the help of aromatherapy and teach them to work on their psycho-emotional state.

In ancient China, vegetable essential oils were burned to fumigate rooms, the Egyptians added them to solutions for embalming the dead, and the Romans took them to the baths. But science has taken up this relatively recently. The term "aromatherapy" was introduced in the 1920s by the French chemist Rene-Maurice Gattefosse.

Plants certainly have useful substances. For example, willow bark was chewed since ancient times to treat inflammation, and then acetylsalicylic acid, now known as aspirin, was discovered in it. But it is one thing to take medicine in pills, and quite another to inhale it. How to confirm that the smell has a therapeutic effect? What is the physical mechanism of influence? In aromatherapy, only subjective, unverifiable descriptions are given. For example, it is reported that the smell of rosemary clears the mind and improves memory, lavender calms and relieves stress, anxiety, depression, and treats insomnia. Juniper oil has a total of 17 beneficial effects, ranging from aphrodisiac to sedative.

The Science of Fragrance

Since the 1980s, a new scientific direction has been developing - aromacology, that is, the study of how odors affect physiology and health. In 2007, American scientists analyzed all the articles that published data on the healing effects of odors. Only 18 of them were recognized as accessible for scientific analysis, and even then with certain reservations. It is difficult to conduct such studies, because they contain a lot of subjectivity, it is not clear how the experimental technique affects the result, and, most importantly, it is not known what is the mechanism of the effect of smell on the body.

Perhaps the molecules of the aromatic substance directly affect the olfactory neurons and then the brain or the endocrine system. Or chemical substances penetrate the blood through the nose or the mucous membrane of the lungs and then spread throughout the body. This is confirmed by experiments on rodents, in which molecules of inhaled essential oils were found in the blood. In other experiments, rats calmed down by inhaling cedrol, a component of cedar, although their sense of smell was damaged. Of course, treatment with odors would be convenient, because the effect after inhalation is instantaneous, and the dose of the substance is required much less than when taking tablets. But in order to develop evidence-based aromatherapy, you need to understand the mechanism of action of the smell, and this is still a long way off.

Interesting results were obtained by the experiments of scientists from Austria with linalool, the main component of lavender oil. When it was applied to the skin of the participants in the experiment, their systolic blood pressure (upper) dropped slightly. This can be considered as an analogue of massage, but the therapeutic effect of essential oil is hindered by the fact that massage itself calms and relieves tension.

In Russia, the project "Influence of the odor environment on the physiological status and cognitive processes of a person" is supported by the Russian Science Foundation. Its participants are from the A.N. Severtsov Institute for Problems of Ecology and Evolution of the Russian Academy of Sciences, the Institute for Information Transmission Problems named after A.N. A. A. Kharkevich and Oryol State University found that the smells of lavender and mint improve the memory of schoolchildren aged 10-11 years. Analysis of participants' saliva before and after the experiment showed that inhaling mint most significantly reduced levels of the hormone cortisol, which regulates stress. Since high levels of cortisol in the body have been shown to impair memory in other studies, the scientists conclude that mint relieves stress.

Solid emotions

All observed effects can be explained differently - through psychological impact. That is, a person reacts to the smell according to his experience and expectations, as well as through training. This hypothesis is supported by the fact that people experience emotions, change their behavior in accordance with whether the smell is pleasant or not. For example, visitors to a supermarket that smells good are more likely to help other shoppers. Employees of companies also work better, set themselves higher goals, if the room smells good.

Another factor is pre-formed representations. When 90 female students were told that the pleasant smell of the room was relaxing, their heart rate and skin conductivity actually decreased, even though they only sprayed lavender and orange neroli oil. All students noted that their mood improved. They said the same thing when they were in a room with a placebo, that is, with an odorless substance.

Supporters of the psychological hypothesis believe that the chemical nature of the smell is secondary, the main thing is the mental effect. To some extent, this is evidenced by cultural, individual and even gender differences in the perception of smells. For example, men who walked through the woods for three days in a row had a decrease in the level of the hormone adrenaline. There is also evidence that aromatherapy alleviates depression. In general, so far the psychological hypothesis of aromatherapy is better supported by experiments.

Whether aromatherapy is scientific or not, it should not be forgotten that the components of essential oils can cause allergies, especially with prolonged exposure.

A few years ago, the question of whether odors affect a person or not was practically not studied, but today scientists around the world are studying this topic and are becoming more and more convinced that this influence turns out to be very large.

First of all, manufacturers of perfumery, cosmetics, various hygiene products, means for restoring order and cleanliness in the house and outside it use this influence. The influence of aromas on a person can manifest itself in a completely surprising way: some can attract like a magnet, others, on the contrary, repel, some can cause delight, others - complete rejection. Engaged in the study of this complex topic is a special science - olfactronics.

The effect of different aromas on a person

Smell is one of the human senses, another way for a person to always be in touch with the world that surrounds him. Although with its help a person receives a very small amount of information - only 2%.

But how exactly do smells affect a person? It is the sense of smell that reacts to external stimuli faster than other sense organs and transmits a signal to the brain. A person catches the smell instantly, although, often, at an unconscious level.

Together with the air that a person inhales, air molecules enter the cells of his olfactory epithelium, as a result of which the epithelial cells are irritated. After that, through the olfactory nerves, the signal is transmitted already to the cortical region of the sense of smell of the brain. There the signal is processed. Those parts of the brain that are part of this center are closely connected with the limbic system, and it, in turn, is involved in ensuring that the constancy of the internal environment of the body is not disturbed. In addition, there is an action of regulation of autonomic functions, the formation of an emotional background.

How can smells affect health and mood?

Many do not know, but aromas can affect both the physical and mental state of a person, they can have a tremendous impact on changes in mood. There are even smells that improve mood. Indeed, having inhaled the aroma of your favorite flowers, everyone will probably smile involuntarily, the mood from such a smell will immediately improve, and the world will seem a little better.

To date, the effect of odors on health has already been well studied. It became known that different odors affect human health in different ways.

In order to get rid of depression and blues, the aromas of the following plants will help:

  • Lemon.
  • Chamomile.
  • Orange.
  • Eucalyptus.

Aromas can have a positive effect on a person's condition in case of colds. Then you should seek help from the following plants:

  • Chamomile.
  • Grapefruit.
  • Lemon.
  • Mint.
  • Eucalyptus.

It is important to remember that you should not fill the entire space with aromas. Everything should be in moderation. Only then will it be useful.

Smells affect the mental state of a person. Most people feel happier when they inhale the smell of pine needles or citrus fruits. Life immediately becomes brighter, as if new, bright colors appear in it. This can be explained at the subconscious level. A walk through the forest or a juicy orange always evokes only positive emotions. Those places or objects that smell of rose, lily of the valley or jasmine will also please. But there are those aromas that cause discomfort and even a severe headache. This is bird cherry and rosemary.

There are fragrances that are absolutely unique in their effect. They are able to restore spiritual harmony, calm, help to find harmony with the outside world and with oneself. These include, for example, rose, ylang-ylag, hyacinth.

How do scents affect mood?

All citrus fruits, magnolia, patchouli, cedar, as well as the smell of cinnamon will help raise it. Ginger, bergamot, violet will also cheer you up. A simple way, but very effective. Just inhale the aroma and no need for any pills. Aromas that uplift the mood and can improve immunity are lemon balm, geranium, sandalwood, neroli.

Many believe that aroma can only enter the human body through the nose and lungs, but this is an absolute misconception. Human skin can also contribute to the penetration of odors. For those who do not believe, you can conduct an experiment - rub the soles of your feet with a head of garlic. After a few minutes, you will definitely feel its taste in your mouth.

Do smells affect relationships between people?

Smells have a pronounced motivated effect.

Despite the fact that sometimes they are not tangible, only thanks to them, on an intuitive level, sometimes friends, lovers find each other. And such alliances can take shape for life. The role of smells in relationships, of course, is unshakable. It will never be comfortable together for people whose smells are not compatible, such a union will surely break up. Attractants or pheromones act with incredible force, attracting people to each other literally at a physiological level. This is the very chemistry of feelings, about which so much has already been said.

Communication at the level of smells exists not only among people, but also among animals, and even insects. This is how small butterflies and large mammals communicate.

The scents you wear all the time stick in your memory, albeit unconsciously. Therefore, it is very important to take good care of yourself. In addition, women who have decided on the choice of perfume and are already in adulthood should not change perfumes, as this may affect their relationship with their loved one. He is already accustomed to the smell of your perfume, for him it is your smell. His loss will be tantamount to losing you as a woman.

How does the human body smell?

As already mentioned, each person has his own unique smell. It is on it that lost animals find their owners. A newborn baby only recognizes its mother by smell. It goes without saying that the natural human smell is the secretions of the sweat glands.

These secretions have not yet been sufficiently studied, but many scientists are now working on this problem. It is even believed that with a complete study of sweat, it will be possible to study the inner world of a person, since it is through sweat secretions that the external world and the aura are connected.

Sweat secretions have a different smell depending on the situation in which they appeared - it can be intense sports, or a situation of fear, a stressful situation, happy moments of life, intense mental activity. The type of allocation depends on the type of work.

With age, the smell of the human body changes, this is due to the production of new substances that are not typical for people of young and middle ages. But the effect of odors on the body does not change.
We perceive the natural human aroma at the subconscious level. We do not seek to feel it purposefully. This happens randomly. And the signal is processed by our brain, often letting us know whether this person is right for us or not.

Why a person smells one way or another is difficult to explain. This is due to a number of different features. First of all - the features of the hormonal and immune systems and bacteria that live on human skin.
Women are more sensitive than men. But in the psychology of a man, it is laid down to react to female enchanting aromas much more strongly.

When communicating, a man and a woman who initially approached each other in aroma, they, as it were, check each other for further compatibility. A man is more and more fascinated by the smell of a woman, he produces more and more testosterone (read:). Then the woman also produces a response hormone and the response game begins. This feeling can be called love at first sight. Sometimes it continues until the last breath. And here the influence of aromas on the human body is by no means exaggerated. It really does happen.

It becomes obvious that smells are something that has tremendous power over us. Often, a pleasant smell lifts our mood, smells often help us in communication. And despite the fact that sometimes we simply do not notice them, do not feel them, but in fact we feel them, they take possession of us. The world is ruled by smells, instincts. We like the person. What do we like about it? Is it possible to accurately answer this question? Eyes, hair, smile, gait, his state of mind ... And we were attracted by the smell. Because it is a smell that is compatible with ours. Let it not be felt, it acts subconsciously, but still it acts, acts on the human psyche.

  • Reactions of our body
  • Choosing smells
  • The Power of Associations

The value of our sense of smell is often undeservedly downplayed. However, the results of new research by scientists in this direction demonstrate that the effect of smells on a person is actually huge. Moreover, smells can enhance concentration, memory and mental endurance.

Until recently, the mechanism of action of odors on our brain was little understood. But today the minds of researchers are absorbed in the question of the influence of smell on our behavior and perception - it turns out that with the help of smells it is even possible to treat certain diseases. So, in one of the French clinics, smells are used to help “reboot” the brain of patients in a coma and bring them out of this state. Smells have found their place in the world of art, where they create a special atmosphere with their help. For example, in the New York Children's Museum, the aroma of fresh homemade bread, just taken out of the oven, reigns.

At the same time, scientists have noticed that smells help to concentrate better, assimilate information, increase efficiency, and therefore can be used to improve one's own performance. But to understand how scents are associated with high grades in school and career achievement, let's look at the inner workings of our brain and how and why it reacts to various olfactory stimuli.

Reactions of our body

Smell is volatile molecules, and not the same ones at all. A single odor can be made up of different molecules, and the olfactory environment in a room can be made up of a range of odor sources. Molecules, getting into the nose, act on certain receptors, and they transmit data to the brain about the concentration, nature and duration of exposure to this very smell.

First of all, information enters the olfactory bulb, then it is transmitted to the cerebral hemispheres, and from there to the limbic system. It is she who is associated with human emotions, memory, sleep and the sexual sphere. The limbic system forms emotional reactions to smells, which is why they primarily affect our internal state - we feel alert and full of energy, or, conversely, we relax, feel calm and sleepy.

In addition, odor molecules enter the pituitary gland, which produces hormones that are responsible for growth, metabolism and reproduction. The pituitary gland also produces hormones that connect it like bridges to the outside of the brain. This is where the most complex thought processes take place.

An important role in the development of olfactronics (the science of the influence of odors on the brain) was played by tomography. Skeptics who believe that the sense of smell is not so important for us, had to back down under the pressure of demonstrative experiments. Experiments have shown that under the influence of certain volatile molecules, various parts of the brain are activated, which means that aromas really affect its work.

For example, on tomographic images, it was clearly seen that the smell of lavender activates the hippocampus (emotions), the thalamus (connection with the senses) and the hypothalamus (it produces hormones that affect brain function). At the same time, the gyrus, which is responsible for touch and movement of the limbs, significantly reduced its activity under the influence of lavender, which means that this plant can be successfully used to stop epileptic attacks. Lavender inhibits the activity of the sympathetic nervous system, which is activated during stress - that is, it can act as a sedative.

Moreover, lavender essential oil contains a very important substance for our life - serotonin. By the way, it is also found in hashish and our brain. Serotonin performs a large number of tasks. Its lack provokes an increase in pain sensitivity, serotonin is responsible for motor activity, improves mood and gives a feeling of joy. If there is too little or too much of it in the brain, it can cause mental disorders.

Choosing smells

Each smell has a certain effect on our nervous system and the body as a whole. Some help to collect thoughts and increase tone, others relax, which means they interfere with hard work.

For example, lavender, lemon balm and thyme activate the sleep area in the brain, but eucalyptus, rosemary, sage, lemon, basil and mint relieve drowsiness, give vigor and a desire to work. The smell of wormwood and lemon makes a person more precise and faster in his studies.

Lavender, sage and eucalyptus improve memory, so they are great helpers for students preparing for a session. The top stimulating scents were cited by the researchers as lemon, mint, rosemary, and neroli oil, which is extracted from orange blossoms.

For example, in Sweden, experiments were conducted that showed that lemon essential oil, the vapors of which hovered in the office, helped secretaries make 54 percent fewer typos and errors in documents.

But the essential oil of calamus and the smell of valerian root, on the contrary, soothe and relax, which can be used in cases where it is vital to get enough sleep before an important event.

The Power of Associations

In addition to the fact that smells trigger certain chemical reactions in the brain, aromas have another effect - sensing them, we fall under the power of associations. It all depends on what events, pictures, feelings and emotions this smell accompanied. Associations can be both national and individual.

For example, the smell of camphor (generally pleasant) evokes negative associations with the disease for many, because camphor is part of rubbing ointments and other preparations. From the smell of incense, believers have a feeling of holiness, joy, bliss - and all because churches are smoked with incense during divine services. Among the inhabitants of eastern countries, such as India and China, incense will not cause such emotions - its role is played by juniper, from which incense is made for temples.

The smell of gaultheria provokes completely different emotions in the inhabitants of the UK and the USA - in the United Kingdom, this plant was previously used in the manufacture of medicines (therefore, the associations are negative), and in the states they make sweets from it.

How to benefit from smells?

In order for smells to become our allies, it is necessary to remember two main rules.

1. The fragrance should not be too strong. This is exactly the case when it is better to underdo than to overdo it. Too strong odors cause a headache - in this case, it is not just the result of a long contact with a source of intense odor, but also a warning mechanism.

It works like this: there is a special nerve on the face that reacts to a strong concentration of volatile substances in the air. The nerve sends a signal of danger to the brain, which spreads a feeling of discomfort throughout the body. Thus, the brain motivates a person to get away from the source of a strong smell that can be harmful to health (this can be smoke or toxic chemicals).

2. To make the effect of smell on human performance as effective as possible, use its physiological effect on the body and associative memory at the same time. Accustom yourself to the same scent that you will use at the beginning of the work or study process. Associations will work, giving the brain a command: “Attention! Need to concentrate! Now the work will begin!

It can be an invigorating toilet water or essential oil, or maybe fresh herbs or a lemon cut in half. You can light an aroma lamp or sprinkle perfume on your wrist, and then smell it. The main thing is not to use smells with a sedative effect for this purpose, because in this case the associations will go against the natural reactions of the brain.

Perhaps the time is not far off when smells will be widely used to increase the efficiency of mental activity in schools, universities and offices. But now everyone can apply this experience to achieve success in a career or study.

The ability to smell and distinguish smells plays a huge role in the life of animals. Smell for many of them is quite an important sense in hunting or escaping from predators. So, hoofed animals smell a creeping enemy from afar, which allows them to hide in time from his fangs and claws. Representatives of the cat find their prey by smell, and wolves and dogs can smell the trail. In many species, babies and mothers, as well as other members of the same group, recognize each other by smell. In general, animals cannot do without the sense of smell.

People are also animals, albeit highly organized ones. But at the same time, they stubbornly ignore the importance of smells, preferring to keep in touch with the outside world through touch, hearing and sight. Odors play a rather aesthetic role (smells or stinks), and in some cases can warn of danger (gas, rotten food, smoke, chemicals). We can distinguish the most intense and memorable smells - favorite food, flowers, perfumes; we can even remember how the people we love smell like.

But if we talk about the impact of smells on the behavior and condition of a person, the sense of smell in this case is significantly underestimated and even treated with a bit of irony. But nevertheless, experiments conducted in America showed that smells affect not only our mood, but also our behavior, as well as the general condition of the body. They can change blood pressure, heart rate, make a person aroused or sleepy. Experiments have also shown that some aromas can remove depressive states and improve the emotional background in patients with mental disorders.

Best of all, a person is affected by natural aromas contained in herbs, fruits, berries or animals. Smells enclosed in vegetable essential oils have a positive effect already at a low concentration.

Our ancestors have long thought about how smells affect humans. The ancient sages were well aware of the magical properties of aromas, so they used them to enter various emotional states. Almost two millennia BC, myrrh and frankincense were placed in the walls of temples so that believers would experience certain states when visiting a sacred place. Five hundred years BC, the first incense factory appeared in Corinth.

In the holy book of Muslims, incense is compared to food that awakens the spirit - and this is really true. The nerve responsible for the transmission of olfactory signals is directly connected to the brain. The nose is the only human sense organ that has no intermediaries. After all, sight, touch, taste and hearing are connected to the brain by a whole series of series-connected nerves, and only the nose can send information to our brain, bypassing long chains.

Due to the fact that the sense of smell is directly connected with the limbic system, odor molecules can have such a profound effect on our emotions, psyche, and consciousness. And, according to scientists, the effect is provided even with a small, almost imperceptible concentration of a fragrant substance in the air.
