The influence of rancid smell on human body, foul smell, is an unpleasant smell emitted by "smelly group" containing sulfur. When the human body inhales a lot of rancid odor, the harm is more serious. Let's learn more about the influence of rancid smell on human body.

Effect of rancid odor on human body 1 1. The most direct consequence is respiratory infection, such as cough with pus and phlegm.

2, if inhaled for a short time, the impact is not great. Long-term chronic inhalation can cause cancer, hypertension and so on.

3. Food undergoes complex changes in the process of corruption, and many unpleasant substances are decomposed. For example, protein decomposition products include amines, hydrogen sulfide, mercaptan, indole, fecal odor and so on. , are strong air substances, smell disgusting. Fatty acids rancidity produces aldehydes, ketones, etc. And further decomposed to produce a special rancid taste.

Among them, hydrogen sulfide is a toxic gas, and a large amount of hydrogen sulfide gas is very harmful to human body. After exposure to high concentration of hydrogen sulfide, headache, dizziness, fatigue, ataxia and mild disturbance of consciousness may occur. Symptoms of eye and upper respiratory irritation often appear first. Symptoms of hydrogen sulfide poisoning: mild poisoning: manifested as photophobia, tears, stinging eyes, foreign body sensation, runny nose, burning sensation in nose and throat, accompanied by dizziness, headache and fatigue. Moderate poisoning: symptoms such as dizziness, headache, fatigue, nausea, vomiting, unsteady walking, cough, dyspnea, itchy throat, chest compression and disturbance of consciousness appear. Immediately, the symptoms of eye irritation are strong, including tears, photophobia and stinging eyes; Severe poisoning: manifested as dizziness, palpitation, dyspnea, slow movement, followed by restlessness, unconsciousness, vomiting, diarrhea, abdominal pain, convulsions, rapid coma, complicated with pulmonary edema and brain edema, and finally death due to respiratory paralysis; Extremely severe poisoning: if you inhale 1 ~ 2, you will suddenly fall to the ground and stop breathing instantly, that is, you will die of electric shock.

The rancid smell of food also contains spores produced by mold, which is harmful to health. Mold spores are invisible to the naked eye, and respiratory diseases can occur when exposed for a long time or in large quantities.

Therefore, when food rots, it must be cleaned up in time, and windows should be opened for ventilation.

Effects of rancid odor on human body II. Smell can affect people's mood. Do you know the magic of incense?

The most distinctive function of the human body is probably the nervous system. The sense of smell has always been the most sensitive organ of human beings or other animals. Smell can be transmitted to the brain through the nose, giving people a special feeling. Different smells can stimulate the brain to respond immediately. The brain is the "highest command" of the human body, directing all tissues and organs of the whole body to work in an orderly manner and respond to various emergencies. Therefore, aroma can give orders to all parts of the body through the "supreme command" of the brain and do things that drugs can't do.

Effect on respiratory organs: When people smell the fragrance, they will take a deep breath unconsciously. If it is irritating, it will cause cough and so on. This is because the substances that make up the odor directly damage the mucosa of the respiratory organs.

Effect on digestive organs: The smell of delicious food will greatly increase people's appetite and produce hunger. The rancid smell can inhibit gastrointestinal activity, nausea and even vomiting.

Influence on circulatory organs: Good smell can make people feel happy physically and mentally, calm down, lower blood pressure, eliminate excessive tension and improve work efficiency.

Effect on skin: Smell will change skin resistance.

Influence on mental activity: the stench will make people have a headache, be impatient and lose their desire to move; On the contrary, it smells refreshing.

Smell is harmful to the body, and fragrance is beneficial to the body, especially some special scents, which can change physiological reactions such as blood pressure, and their effects can be comparable to antihypertensive drugs and relaxation methods to relieve mental stress.

Shennong's Classic of Materia Medica records: "Those who are fragrant have positive qi, and those who are full of positive qi will eliminate evil and filth." This shows that the use of spices to clear qi can stimulate the healthy qi of human body and achieve the purpose of health care and treatment. Incense and medicine are homologous, and 80% of spices are Chinese herbal medicines. Many traditional Chinese medicines can emit unique fragrance, which belongs to the best of spices. Plant medicines include perilla leaves, ephedra, Pogostemon cablin, Eupatorium odoratum, etc. Animal medicines include musk and dragon birthday incense. In ancient times, people like to make these fragrant drugs into medicinal pillows or sachets, which can emit their fragrance for a long time and achieve the effects of preventing and treating diseases and maintaining health.

Physiologically, there is an oil cell in the petals of fragrant flowers, which can secrete volatile aromatic oil. When aromatic oil molecules are dispersed in the air and come into contact with olfactory cells in human nasal cavity, the peripheral receptors of olfactory nerves will be excited, and this excitement will be transmitted to the cerebral cortex, and we will feel the fragrance of flowers. The cold fragrant pills in A Dream of Red Mansions are specially made of four kinds of attractive petals, and the smell is indescribable. When we smell the intoxicating fragrance, we will naturally throw our troubles away and feel the joy of "flowers don't intoxicate people", so our nervous nerves will relax and our brains will have a good rest, and we will unconsciously forget the disease, which is very beneficial to human health. Therefore, the role of smell can not be underestimated. If you can make good use of it, it may give you an extraordinary and wonderful experience.

With the increasing pressure of life, it is difficult for a person to relax or sleep peacefully. Most people have been taking sleeping pills, but this will have more side effects on the body. Aromatherapy is one of the natural ways to relax and sleep by stimulating nerves with odor, and there are no side effects. There are various fragrances that can promote relaxation and sleep, which are beneficial to people's health. Insomnia is complicated. Here, only from the perspective of incense and incense, they are used in harmony with each other. Here are some spices that can improve sleep. No complete formula is given here, only the use of some single ingredients is mentioned. I need reasonable compatibility and recombination.

The influence of rancid smell on human body 3. I can always smell foul smell. It turned out that there was something wrong with her "brain"!

Clearly there is nothing around, but Xiao Chen always smells a smell of "corpse decay", and this stench also appears in various places from time to time. After asking the people around him, Xiao Chen found that only he had smelled the smell. Because of this stench, she also made a lot of oolong, and was even ridiculed by people around her as "there is something wrong with her brain."

Xiao Chen is very troubled. Is there something wrong with her nose?

After going to the hospital for examination, the doctor told him that there was something wrong with her brain.

This is not to say that Zhen Chen Jr. suffers from mental illness and hallucinations, but actually has a tumor in her temporal lobe.

We often associate frequent headaches with brain tumors, but in fact, not all severe headaches are caused by brain tumors, and brain tumors are not just a symptom of headaches.

Three main symptoms of brain tumor: headache, vomiting and decreased vision.

Headaches caused by brain tumors are different from colds and migraines. It often happens in the middle of the night or at three or four o'clock in the morning, and sometimes wakes up in a deep sleep. After getting up for a while, the headache symptoms will gradually ease. This kind of headache will become more and more serious as time goes on.

When patients with brain tumors have severe headaches, they often suddenly vomit violently, but after vomiting, the headache will be alleviated. Most of them did not have abdominal distension, abdominal pain, nausea and other symptoms before vomiting, which was caused by the increase of intracranial pressure caused by tumor compression. Increased intracranial pressure can also lead to visual dysfunction, such as decreased vision and narrowed vision.

If these three symptoms appear, we must pay attention to them and go to the hospital for examination and treatment as soon as possible.

Abnormal behavior may be a real "disease" in the brain.

If a person behaves strangely, most of us will think that he is mentally ill, but we often ignore the possibility that he has brain problems. The compression of brain nerve by tumor often leads to various abnormal behaviors and consciousness of patients.

Xiao Chen's phantom sense of smell is due to her temporal lobe brain tumor, which leads to abnormal olfactory center. She often smells rotten corpses, rotten eggs and pungent chemicals that don't exist. If tinnitus and deafness (auditory nerve), language disorder (language center), visual impairment (optic nerve) and drunken gait (cerebellum) occur, we should also be vigilant and check whether there is a tumor in the corresponding nerve center.

If there are numbness, pain and other abnormalities in half of the body, head and face, it may be that the brain tumor is oppressing the trigeminal nerve conduction pathway; There is pain in one limb, loss or disappearance of warm feeling, which may be in danger of lateral brain tumor; If unexplained convulsions or seizures occur, the possibility of brain tumors should be suspected first, because brain tumors can cause brain edema, stimulate abnormal discharge of nerve cells, and cause local or systemic convulsions.
