The smell is a bit smelly, and I get used to it when I smell it

There is a word called "feeling the same", but there are many things in the world that cannot be affected. For example, people's sense of smell has their own temper, and some people cannot smell their feet or body odor, but the people around them are smoked.

Regarding the magical of the sense of smell, the ancients said, "The room of Chilan has been smelled for a long time, and the abalone is not smelling." Why is this? Is your nose tired? Today, let us explore the magic of the sense of smell together.

Does smell of smell really exist?

The reason why people can determine some things from a complicated world, often this judgment rely on smell to achieve.

On the olfactory epitaxe behind the human nasal cavity, there is a "sniffing ball" used to perceive the smell. The flavorful particle molecules in the air enter the nose to irritate the olfactory epithelial cells, and then generate an electric signal, and then transmit the electrical signal through neurons, first pass to the sniffing ball, and then to the brain. When you smell the smell, the brain receives the signal.

However, many times the signal's conduction is not very accurate. Specifically, in life, people with appreciation cannot perceive the odor on their bodies. It is called "smell fatigue".

Specifically, in general, when the sodium ions and calcium ions are inflow into the cells when the receptor cells (sagamenucleotide protein occasionally somatoscopy) are attached to the specific protein on the specific protein, and And perception of impulse (de -polarization). The pathway of sodium ions and calcium ions is the ionic channel of the nucleotide gate (feeling device cells transform the external electromagnetic signal or chemical signal into an intracellular electrical signal. In this process Generate a biological signal).

When people continue in a environment, when they smell a certain smell, after the smell of the olfactory neuron responses and exfoliates, G protein (can be combined with diic acid phosphate, a type of signal conductive protein with GTP hydrolyzed activity) medium) The second merit of the guide activates adenolate rings, increases the concentration of cycloshenoside in the cell, and then opens the codonicide channels. Next, the rapid internal flow of calcium ions will trigger a chemical -grade joint reaction trigger smell fatigue, which will cause the cyclic nucleotide portal control ion channel to close and make similar odor molecules from activating the receptor.

In other words, the reason why smell fatigue occurs is because the olfactory nerves are repeatedly stimulated by the same smell. At the same time, if the smell concentration does not become stronger, the receptor related to the molecule may gradually be similar to similar molecules due to a series of joint reactions. Activity, the brain's excitement of this taste is also decreasing, and the reaction becomes slow. So over time, some people cannot smell the taste of themselves, and they cannot respond quickly to the incense and smell.

In fact, this is the result of evolution, which can make our bodies not sensitive to continuous stimulation, so as to prevent excessive load of the nervous system, thereby responding to unusual, special, and new stimuli. It is also simple to solve the problem of smell fatigue, just go to a new environment. It has been a long time in the environment of birds and flowers, and may not smell it for a while, but as long as you go out for a while to enter again, your nose can quickly capture the fragrance.

What is the lack of smell?

In addition to fatigue fatigue, the problem of lack of smell in recent years has also attracted people's attention. "Spring breeze flowers and plants" and "night melon have more than heart". The sense of smell is a tool for people to perceive everything. However, there are also some patients with "smell of smell" lacking such abilities.

This crowd either lacks a normal sense of smell or cannot perceive the smell. Some people may be temporary, and some people have been troubled by this throughout their lives, such as traumatic smell. There are many causes of smell of smell, including the acquired factors such as nasal mucosa inflammation, blocked nasal cavity, and temporal lobe damage.

This condition has an impact on their lives. The general point is to bring inconvenience to life. They cannot feel the refreshing aroma, and they lack the perception of "fragrance" in their diet.

Even more threatened their lives. Sometimes the sense of smell can help us avoid risks. When smelling the smell, normal people will respond quickly; when they smell the strange smell of food, people will discard them. However, people with a sense of smell cannot rely on the sense of smell and avoid such risks.

In addition, this condition will induce a series of psychological problems. Many patients will conceal this fact in order to integrate into the surrounding environment, and even pretend that they can smell the taste. People with a sense of smell are very concerned about their own experience and are usually accompanied by social anxiety. It is impossible to play a sense of smell in interpersonal communication. It needs to rely on others to help identify the smell. The lack of autonomy makes them quite troublesome, frequent frustration, and these psychological problems will last.

Studies have shown that the sense of smell of smell will increase the pressure and depression level of patients.A British study shows that the proportion of depression and anxiety of the sense of smell disorder is higher. Among these people, up to 92%of people are facing difficulties in eating, 57%of them have been isolated, 54%of people have interpersonal disorder.45%of people feel anxious, 43%of people have depression.At the same time, female patients have more problems in social and family dysfunction than men.Therefore, in our lives, we cannot ignore this group, and people who pay attention to and care for the sense of smell are indispensable.A sense of smell is an extremely important sense of human beings. Many things exude a unique taste. We can rely on odor to distinguish.In the experience of people's perception of odor, every moment is a personal olfactory memory of personal exclusive.
