In fact, each organ has a set of innate self-defense mechanism that can deal with aging, injury, mutation, foreign body invasion, etc. Some symptoms are actually The body opens its own defensive system, actively defeating the enemy's performance, and let's see how each organ protects itself.
The immune system grinds bacteria
Fever is not a disease, but a symptom.He Yunhe explained that a certain degree of fever can increase the activity of the immune system of white blood cells and promote antibody production, the body in a state of war preparedness, is a self-protection mechanism. , Body temperature exceeds the growth of pathogens suitable for temperature, can play a bacteriostatic effect. At this time do not have too much anxiety, fear .Body temperature below 38.5 ℃, do not be anxious to use antipyretics, can drink warm water or oral rehydration salts, at the same time Use of physical cooling. Exceed this temperature can be used as appropriate, antipyretics, the purpose is to reduce the irritability and discomfort caused by fever .Hot fever or persistent fever, all indicate some serious problems with the body, such as autoimmune diseases, tumors, Infection, etc., need timely medical treatment
Tears streaming away rubbish
Tears is a weak acid liquid, in addition to 98.2% of water, there are lysozyme, immunoglobulin, lactoferrin and other substances, with the role of inhibiting bacterial growth.Lysozyme in 5 to 10 minutes to kill 90 % ~ 95% of the bacteria. When the eyes fall into the dust and other foreign matter, a large number of tears can wash away foreign body, and effective defense to protect the cornea and conjunctiva from injury from a psychological point of view, tears can ease the mental burden Whether sad tears, or cried, can effectively release emotions.University of Minnesota studies have shown that emotions caused by moving tears and other catecholamines, which is released by the brain under pressure of a chemical substance, accumulation of too much will Increase the risk of cardiovascular and cerebrovascular disease.However, crying too long damage memory and attention, and even reduce the immune function.Lack of lacrimal gland function, long-term wear contact lenses, vitamin A intake, long time to see the screen, the long-awaited Air-conditioned room or heating room, eye drops, etc., may lead to decreased secretion of lacrimal gland, resulting in dry eyes, is not conducive to eye health.
Stomach vomit to get rid of germs
Ingestion of toxic substances, or too complicated, too cold, too hot and other irritating foods, or binge eating may cause nausea and vomiting.He said that this is the gastrointestinal tract to prevent bacteria invasion, the regulation of physiological function of a stable Self-protection mechanism, in order to excreted harmful substances, to stimulate the stomach to minimize vomiting, stomach irregular movement coupled with gastric acid secretion, to the esophagus, to the mouth, are very uncomfortable. Should not arbitrarily use antiemetic drugs, so as not to allow the retention of harmful substances in the body, and further harm to health.If accompanied by bloating, mostly due to eating too much indigestion, can be appropriate to promote gastric motility drug. Jet vomiting and more for the central nervous system Sexual disease caused by increased intracranial pressure, common in encephalitis, meningitis, brain tumors, cerebral hemorrhage and other diseases. Encounter this situation, or vomiting recurrent, accompanied by abdominal pain, fever and other symptoms, should seek medical care immediately. If retching often, excluding gastrointestinal diseases, to consider whether suffering from pharyngitis, ear to nose and throat treatment.
Respiratory tract cough clear foreign body
Beijing Electric Power Hospital Department of Respiratory Medicine, deputy chief physician Zheng Jianhong said that when the respiratory mucosa by foreign body, secretions (such as sputum), or the existence of allergic stimulation, inflammation, it will cause reflex cough, help remove harmful substances invaded the respiratory tract. In the same token, sneezing can spray foreign objects (such as dust, pollen, etc.) that enter the nose and prevent them from entering the body, and when sneezing, you can let the cough Sudden contraction of the body muscles, produce heat, to resist the cold.Many people think that coughing, sneezing is a cold, it is a very wrong understanding of rhinitis, asthma, bronchitis, gastroesophageal reflux, heart disease, may lead to cough. For example, half asleep suddenly chest tightness, breathless, cough, may be caused by heart disease. Abuse of cough medicine, antibiotics, cold medicine to cough, dirt will stay in the respiratory tract, is not conducive to the elimination of foreign objects, but also delay To find the cause. ▲
The brain yaws to make up oxygen
Once yawning time is about 6 seconds .In the meantime, the people plug, listen to the whole body nerves, muscles completely relaxed, body and mind to get a short break, has an important physiological protection .Yam deep breathing exercise can promote blood circulation, increase blood In the oxygen, emit more carbon dioxide, so that more energetic, eliminate sleepy feeling sleepy often Yawn, to remind you that the brain is tired, need sleep rest .When the desk work for a long time, may wish to extend lazy, the head Backwards, playing a big yaw, can remove the sense of drowsiness .Beijing Electric Power Hospital Department of Neurology, chief physician Zhou Guoping pointed out that frequent yawning may be associated with certain diseases .National Institutes of Health pointed out that excessive yawning may be caused by a vagus nerve Reaction, may indicate a heart problem.Clinical findings, about 70% to 80% of ischemic stroke patients in the week before onset, due to cerebral ischemia, hypoxia and frequent yawning phenomenon .Cardiovascular and cerebrovascular disease history Or the elderly, if yawning frequently for unknown reasons, should be promptly to the hospital for examination.
Skin goose bumps warm
Cold, people will chills, covered with goose bumps skin attached to a small bundle of muscle under the pores, called the hair shaft.While the cold wind, the temperature of the skin surface feel the nerve to pass the message to the brain, the brain issued an order, contraction Pits on the skin, the hair shaft begins to contract, and the hairs are erected, which can effectively prevent the body heat from dissipating, which is a cold-resistant self-defense reaction reminding you to add clothes. But also generate heat to help resist the cold.When frightened, the skin may also be goose bumps, which is self-defense caused by nerve chain reaction.
Gut diarrhea toxins
Eating unclean food or having a cold stomach can often cause diarrhea - a signal from the gut to the human body telling you that there are unfriendly toxins in your diet or drinking hot water or adding thick clothing. Can quickly discharge toxins, to avoid further harm to the body.China Medical University Integrative Medicine Hospital Emergency Department He Yunhe warned that do not have diarrhea immediately with antidiarrheal drugs, anti-inflammatory drugs, etc. Not all are caused by inflammation of the diarrhea, Many gastrointestinal tumors, irritable bowel syndrome, also have diarrhea symptoms .Drug abuse not only hinder the toxins, but also may cover up the real condition, delay treatment .If the diarrhea, stool bloody, abdominal cramps, or accompanied by abdominal pain, fever , Vomiting and other symptoms, should seek medical treatment immediately
Ear boils build up a barrier
Earwax scientific name 耵 聍, is the product of the sebaceous glands and sweat glands, with the protection of the external auditory meatus skin and adhesion of foreign objects. Beijing Tongren Hospital otolaryngology chief physician Wang Qi said, like tears to lubricate your eyes, like 耵 聍 also Can play a lubricating effect on the ear, to prevent dry itchy, but also to prevent insects from crawling into the United States National Institutes of Health found that 耵 起 played a significant killing effect on some bacteria.Usually with the chewing, mouth and other sports, Earplugs and more self-discharge ear wax sometimes coalesced into groups, people often pick up pick ear spoon, hairpin, match stick, cotton swab and other ear digging, doing so has many disadvantages .External ear canal skin is very delicate, closely connected with the perichondrium, subcutaneous tissue Less, poor blood circulation, dig ear, improperly easily lead to injury, infection, resulting in boils, inflammation, ulcers, resulting in unbearable ear pain, affecting mouth and chewing, and even lead to perforation of the eardrum. Deeper and difficult to remove.Often dig ear is also easy to make the cutaneous stratum corneum outer skin swelling, blocking the hair follicles, to provide a hotbed for bacterial growth.It is recommended to have endoscopic Remove Earwax department.
