New research | Humans attract each other's "sense of smell"!A appetite and emotions are smelled

People in life often use "seeing the same thing at first sight" and "love at first sight" to describe fate, but you may not think that this attractive depends on the sense of smell.

In the movie "Smell the Fragrant Women", the heroine of the blind eyes rely on the sense of smell to identify different people. A new study also confirmed that the sense of smell determines whether two people can build a close relationship.

The sense of smell is similar, the key to forming an intimate relationship

A sense of smell, as a "five -consciousness" (listening, smell, touch, vision, taste), is relatively not much noticed. In fact, it is an important "tool" for you to make good friends and find a partner. Recently, a study from the "Science" sub -issue "Science Advances" found this mechanism.

Institute of Requests in Relly, the Institute of Science of the Ribet, found that similar to many animals, humans will find friends and partners who match themselves because of the smell of smell.

In order to verify the role of smell in interpersonal communication, scientists have verified through three stages of experiments.

Phase 1:

The research team recruits 20 pairs (40 people) same -sex friends, including half of them. When participants received experiments, they confirmed each other with a sense of intimacy.

In the experiment, they were asked to wear a new T -shirt before going to bed, and the continuous dressing time was not less than 6 hours. In order to ensure the purity of the sample data, participants should avoid contact with perfume and heavy taste food as much as possible.

After the machine processing analysis T -shirt, the researchers concluded that they were intimate partners, and the T -shirt was very similar.

Phase 2:

The research team is included in 25 flavors to score the odor similarity of the 20 pairs of intimate relationships and 20 random pairing personnel.

The results show that the odor score of close partners is very similar, and the similarity is higher than the random pairing relationship.

Phase 3:

In order to further understand whether strangers can enhance their closeness through similar odors, the researchers recruited a new group of participants to ask them to perform mirror games in each other to imitate each other's movements, but they could not talk with each other to judge mutual mutual conversation to judge mutual mutual mutual conversation to mutual mutual conversation to mutual mutual conversation to mutual mutual conversation to mutual mutual conversation. The favorability between.

The results confirmed that "body taste" similar strangers are easier to establish intimate relationships.

According to the above experiments and related data analysis, scientists have found that with the similarities of scent molecules, they predict whether the accuracy of the two people will reach 71%. In other words, "smell" is similar, and two people are more likely to form intimate relationships.

Four functions of the sense of smell are ignored

A sense of smell is a sense of far away. It can feel chemical stimulation through long distances. Little to clothing, food, housing and living, so as to perceive the danger, the function of smell is stronger than you think.

Enhance your appetite

The fragrant food can greatly increase the appetite, and the smell or corruption taste can automatically stay away from people. These are inseparable from the smell of smell.

It is not contradictory for people who love to eat snail powder, stinky tofu and other odor foods. Because this feeling belongs to the sense of smell of the nose, that is, the smell of the mouth, which is different from the "smell".

It is usually not smelling when a cold, and the loss of appetite is certain. This is also the truth.

Help memory

When people smell a specific taste, they can instantly evoke long memories, because the sense of smell has established corresponding nerve reflexes.

Danger

The research published by the American Academy of Sciences shows that the sense of smell can distinguish many scent threatening health and life.

For example, after the smell of chemicals and rotten foods enters the nose, the signal will reach the brain within 100 ~ 150 milliseconds, and reacts within 300 milliseconds, making people unconsciously stay away from bad odors.

When the fire occurs, the smoke produced by some material combustion is usually toxic and has a special odor. After smelling, people can find danger in time, extinguish the fire or escape the scene.

Influence

After people smell the fragrance or food, they will feel comfortable. People with poor sense of smell are usually chronic, indifferent to things and environmental things, anxiety, depression, etc.

The decline in sense of smell will seriously affect the quality of life of people, which not only threatens health, but also causes life to danger. Data show that the chance of accidental disorder patients is twice as good as normal people.

The sense of smell may be the "hidden signal" of the disease

A sense of smell can not only help people distinguish various tastes, but more importantly, its changes are sometimes a hidden signal of the disease, and often given priority to other symptoms.

Slight change

In the early stage of the decline in the sense of smell, it is usually slightly changing, and it is easy to be ignored. If people around you can smell a lot of smells, such as strong odor, moldy taste, etc., but when you can't feel it, you may indicate a loss of smell.

In addition, in life, you must be alert to the sudden change of taste. For example, when you cannot feel sour, sweet, bitter, spicy, salty, etc., you should also pay attention to whether the smell of smell occurs.

Smelling and wrong smell

The sense of smell is wrong: It means that the human body cannot perceive the real smell normally. It may smell the smell but thinks it is fragrant, or feel the flavor as a smell.

Fantasy: It refers to the smell of the human body that does not exist.

The above two situations are often related to factors such as neurological disorder, anxiety or depression. They belong to neuropathy and psychological problems. The function of the olfactory area is actually normal and can be restored after receiving the corresponding treatment.

The sense of smell is affected by many factors, mainly in the following categories:

1. Rhinitis: Bad habits such as environmental pollution and staying up late are easy to cause rhinitis and decline in smell.

2. Trauma and tumor: Fractures of the skull bottom and skull nest may damage the olfactory cells and olfactory nerves, causing a sense of smell. If you suffer from intracranial tumor diseases such as glioma, you can sometimes invade the smell of the smell. 3. Virus infection: When a cold or other virus infections occur, the virus can cause nerve function loss and cause a decrease in smell.

4. Age: Age growth, human nerve function will slowly degenerate, and the decreased sense of smell is one of the symptoms. The olfactory nerves with Alzheimer's disease will also change degenerative changes, causing a decline in smell.

5. Environment: temperature, humidity, and cellular development of cells have a certain relationship. After being stimulated by chemicals with a strong smell, the sense of smell will occur temporarily or permanent damage.

In order to protect the sense of smell, it is recommended that you do it:

Wear masks when the air is not good;

Rinse appropriately with physiological saline to reduce the stimulation of allergens to the nasal mucosa;

Don't pick your nose;

Avoid long -term smelling environments.

Some hospitals have a dedicated olfactory inspection department. When abnormal changes in the sense of smell, they should go to the hospital for examination in time. If no problems are found after the nasal cavity, CT or MRI will be further used for comprehensive examination.
