Why do people smell smells, and why do people smell smells

The reasons are both psychological and physical. Psychologically, it can be said that the lover is out of the eyes, and if he likes it, he will naturally paralyze himself mentally, thinking that the other party is good. Love makes people stupid, probably hormones make the whole world illusory, except for each other, everything else is floating clouds.

Speaking of physiological, physiologically healthy opposite sex is more attractive. A healthy body is mostly manifested in symmetrical cheeks and a full figure on the outside, and a stable mood on the inside.

Because the function of the nose is one of the olfactory organs, and the other is for breathing.

To smell in your nose, you must first have an odor**, which is usually a volatile chemical molecule in the air. When a chemical molecule is inhaled into the nasal cavity, it binds to olfactory receptors. Olfactory receptors are composed of a family of "G protein-coupled receptors", distributed on the surface of olfactory cells, which are located in the olfactory epithelial layer at the upper end of the nasal cavity, about seven centimeters from the nostrils, with an area of about one square centimeter, like the size of a fingernail.

Olfactory cells, on the other hand, are specialized bipolar neurons that specialize into cilia at the tips of cells near the nasal cavity to increase the surface area in contact with odor molecules. The tips of olfactory cells are covered by nasal mucus, which contains odor-binding proteins (abbreviated as OBP). OBP first grasps the odor molecules in the air, and then binds to the olfactory receptors on the olfactory cells, changing the protein configuration of the olfactory receptors, producing a series of signaling reactions, and then activating the olfactory cells, stimulating the electrical potential changes on the cell membrane, and then transmitting electrical signals to the brain.

Ever smelled someone else's smell？If your answer is yes, you may have experienced "hallucinations" – what is medically known as "olfactory hallucinations." Hallucinogenic odors are usually unpleasant:

Some people smell feces or sewers, and some smell smoke or chemicals. It can be caused by a ringing sound or a change in the direction of airflow in the nostrils. Even more creepy is that some patients seem to be able to preemptively hallucinate the onset of hallucinations

This fake smell lasts for a few minutes for the first time. It may recur daily, weekly, or monthly for the following year.

Since our sense of smell governs the taste of the food in our mouths, any food we eat will be contaminated by the smell produced by the hallucination when hallucinations occur. It is evident that the symptoms of hallucinations can seriously affect a person's quality of life. In some extreme cases, it can even lead to suicide.

Patients who produce hallucinatory odors often have a symptom closely related to hallucinatory odors, called paroxysmal hallucinations。In this case, the patient will mistake one odor for another, such as rose, for cinnamon, although it is more common to mistake the original odor for a foul odor. Hallucinatory olfaction and olfactory inversion are both qualitative olfactory disorders, that is, what changes are a qualitative property of our perception of smell.

In contrast, quantitative olfactory disorder implies alterations in olfactory intensity, including anosmia and hyperolmia. Quantitative symptoms can be measured by an objective, standardized test.

Only in rare cases do people with hallucinatory olfactory disorders develop olfactory disturbances, such as anosmia. Interestingly, the symptoms of psychedelic odors usually appear in the nostrils where the sense of smell is the weakest.

It's not that you smell some gas that doesn't exist, it's just that it's just there.

It may have a certain psychological effect, so it will cause you to smell some gases that are not there.

This is because the gas is probably invisible, so it can be smelled.

Maybe it's just some hallucinations under the influence of some emotions!

This is not necessarily smelling, it may be felt, which means that you think you should smell smoke, so the brain itself tunes up the previous olfactory memory.

This may be that you have had a nervous breakdown recently, so take more rest.

Olfactory sensitivity is a good thing, olfactory sensitivity and health are directly proportional, the more sensitive the sense of smell, the healthier, my nose is more sensitive than yours, there are many people with an excellent sense of smell, under normal circumstances, people's sense of smell sensitivity is the highest in childhood, and it will decline later, this process is reversible, and olfactory sensitivity can be improved after lifting training.

Forehead.

Upstairs dripping. Psychic.

Is it possible? Want me to say.

Maybe someone else has a problem with their nose drops!

o(∩_o...Ha ha.

It may be that you are too tired to drop the body.

Didn't rest well. So a kind of a.

It should be that the sense of smell is better, nothing strange, some people are born like this. Ha ha.

Cow man!

It is recommended that you go to the hospital for a check-up, it is normal and fine, but I am afraid that there are other problems!

After all, you need to know what you're doing!

Congratulations, you were a dog in your last life, haha.

Just kidding, it should be a "special function".

You have a very sensitive nose. If you've been born like this, that's your talent, take good care of your nose. It will be very useful to you later.

Maybe it's because you're sensitive!

Maybe it's a flu right now, and your classmates are all colds, but you don't.

It's nothing, it's just that your olfactory organs are more sensitive than normal people, or your olfactory nerves are more developed than ours. There is also a good side to this, such as the fact that you can detect disasters earlier.

It means that your sense of smell is very sensitive.

You can go solve the case.

The police dog is going to be laid off.

Landlord, you're an alien.,Forgive me for taking you to the Academy of Sciences.,There's a bonus.,Nobel Prize in Biology.。。

I'm like this too, and I ended up asking about a lot of odors, maybe you have a very sensitive sense of smell.

Congratulations, you may have a special feature.

You can go solve the case, work hard!

The main thing is the diffusion of molecules with the help of the power of the wind.

Molecular diffusion role definition.

Diffusion is a basic way of mass transfer due to the diffusion of molecules and the thermal motion of atoms caused by the thermal movement of molecules and atoms. Diffusion driven by concentration difference, that is, the migration of material components from high concentration to low concentration area, is the most common diffusion phenomenon in nature and engineering. Diffusion driven by temperature difference is called thermal diffusion; Diffusion that occurs under the action of external forces such as electric and magnetic fields is called forced diffusion.

In chemical production, the diffusion of substances in a large enough space driven by the concentration difference is the most common, and the general molecular diffusion refers to this diffusion, which is the physical basis of the mass transfer separation process and also occupies an important position in chemical reaction engineering. In addition, the diffusion of fluids in porous media is often encountered, and its diffusion rate sometimes controls the rate of the entire process, such as the rate of some gas-solid phase reaction processes. Thermal diffusion is only used in the separation of stable isotopes and special materials, and forced diffusion is rarely used.

Diffusion is temperature-dependent.

According to the theory of molecular motion, molecules are moving at high speed all the time, and when the energy of motion is higher than the binding force between molecules, the molecules are separated from the object itself, and some will fly to the nose and be smelled.

The reason why people feel the smell of fragrance is actually that the molecules of a certain substance spread into the human nose, so that the human olfactory organs produce a series of reactions, forming specific information into the brain, thus forming a certain odor judgment, such as aroma, smell, etc.
