Our immune system can resist the invasion of pathogenic organisms such as bacteria, viruses, parasites, and eliminate the toxic products secreted by them, thereby protecting the body from damage.
Under normal circumstances, if the defense function is performed properly, the body will be protected from infection and disease. Otherwise, the body will suffer from pathological changes when attacked by pathogens, such as infectious pneumonia, viral hepatitis, AIDS, etc. Once the stability of the immune system is destroyed, autoimmune diseases will occur. Such as lupus erythematosus, rheumatoid arthritis etc.
What diseases will the immune system cause?
Low or lack of immune function is easy to be infected, which is called immunodeficiency syndrome in medicine. It often causes a variety of local or systemic infections. Mild people catch a cold, even hepatitis B and hepatitis C viruses, which damage the liver and lead to liver cancer. The more serious is HIV infection, which paralyzes the entire immune system and makes the human body. Loss of the power to fight pathogens, so from AIDS patients, we can clearly see the importance of immunity.
Diseases with low immunity include: colds, coughs, pharyngitis, gastritis, enteritis, pneumonia, bronchitis, tuberculosis, rhinitis, otitis media, hepatitis, cancer, mastitis, skin infections, nephritic functional diseases and other diseases. Generally speaking, except for traumatic diseases, all diseases of the human body are related to low immunity, disorder and hyperactivity.
Immune function is abnormally hyperactive-an allergic reaction to drugs or beneficial microorganisms entering the body.
The manifestations of diseases are: pollen allergy, allergic dermatitis, measles, asthma, intractable headaches, toothache, pink eye, acne, constipation and high blood pressure, hyperlipidemia, heart disease, stroke and other cardiovascular diseases.
Stable immune function (immune disorder)-the manifestations of diseases are: lupus erythematosus, dermatomyositis, rheumatoid rheumatism, pernicious anemia, weakness gravis, psoriasis, ichthyosis, Behcet's disease and diabetes.
Immune monitoring dysfunction-the immune system cannot recognize and remove the abnormal cells produced in the body in time. This is the main reason and determinant of tumors and cancer.
Ways to improve immunity
Whether the body can resist the invasion of diseases depends on the strength of the immune system. 9 simple ways to improve immunity to help you keep the disease out.
sufficient sleep
Staying up all night for a long time will severely damage the human immune system, making it more susceptible to infection.
Staying up late will consume the body's muscle tissue. Modern people stay up late for sedentary work and cause fat accumulation. This change in the body's nutritional content is not easy to be found in the short term, and it will reduce the body's immunity in the long run.
Adequate sleep can ensure physical recovery and energetic energy when waking up. The average adult sleeps 7-8 hours a day, and the elderly cannot be less than 6 hours.
Yogurt
A study by the American Health Association found that yogurt can reduce "bad" cholesterol (low-density lipoprotein LDL) levels and reduce the risk of urinary tract infections by 47%.
The probiotics contained in yogurt can greatly improve the body's immunity and disease resistance.
The calories of yogurt are about 1.5 times that of the same amount of milk, and the pH value of yogurt is low. Therefore, drinking yogurt during the day can supplement energy more than drinking at night, and it is easy to digest and absorb.
garlic
A study by the University of Maryland Medical Center found that regular consumption of garlic not only helps improve immunity, but also helps prevent heart diseases.
As an allium plant, garlic contains bactericidal and antiviral compounds, which help the human body to improve immunity and fight against "invaders." Allicin in garlic can inhibit inflammation in the human body and reduce the damage of free radicals to human cells.
However, allicin is easily volatile when exposed to heat. It is recommended to mash it and leave it for 10-15 minutes before eating, so that alliin and allinase can interact with each other to improve the nutritional value. Allicin has a certain stimulating effect on the intestines and stomach, so patients with gastrointestinal diseases should eat less.
Vegetable Chicken Soup.
A study by the University of Nebraska Medical Center in the United States has shown that vegetables and chicken soup have a certain anti-inflammatory effect, and part of the therapeutic effect of eliminating inflammation caused by colds.
Vegetables that go with chicken soup include: onions, sweet potatoes, radishes, carrots, celery, coriander, etc. A cold easily affects people's appetite. At this time, vegetable chicken soup can replenish energy, improve nutrition, and help restore immunity.
Ginger water, lemonade.
Ginger is a natural analgesic and antidote. It has certain anti-infection and anti-influenza effects. Lemon is rich in vitamin C and has antioxidant properties. Foods rich in antioxidants and vitamin C can protect the body from free radicals and harmful molecules, and promote a healthy immune system.
tea.
After three or four in the afternoon, the body's energy begins to decline. At this time, drinking a cup of tea or coffee and eating some snacks can not only supplement calories, improve work and study efficiency, but also relieve fatigue after continuous work, and maintain autoimmunity through self-regulation System health.
A number of studies have shown that the chemical substance alkylamines in tea can strengthen the immune system's ability to resist infection. For example, jasmine tea is rich in antioxidants, which can help improve immunity; peppermint tea can refresh the brain and improve indigestion. Afternoon tea can also be paired with snacks such as nuts and fruits.
work out.
A report from the U.S. National Library of Medicine shows that exercise can help "flush" bacteria in the lungs, and it can also make white blood cells flow more quickly and improve the immune system's ability to detect diseases.
Daily activities and physical exercise can increase the body's muscle mass and maintain nutritional status.
Modern people work under a lot of pressure, so under the condition of normal physical condition, you can ensure that the amount of exercise is 30 to 60 minutes every five days. Walking more than 6000 steps, cycling, playing badminton, swimming, yoga, etc. are all good choices for increasing daily exercise.
Sunbathing.
A study by the Yale University School of Medicine in the United States found that regular exposure to the sun can help reduce the harm of influenza viruses and other common respiratory diseases.
Adequate vitamin D can also help metabolism and reduce the risk of obesity, and sun exposure is the most cost-effective way to supplement.
Generally speaking, the low ultraviolet rays in the sun at 10 am and 4 pm can not only promote metabolism, but also avoid damage to the skin. The time for each exposure is not more than half an hour.
Keep smiling.
A positive and optimistic attitude can not only reduce human stress levels, but also promote sleep.
Researchers at Stanford University in the United States have discovered that laughter can increase the number of antibodies and immune cells in blood and saliva, and can also excite parasympathetic nerves, reduce adrenaline levels, and relieve fatigue. It is a good medicine for improving immunity.
Supplement some nutrients to help enhance your protection and immunity.
Protein is the most important nutrient for maintaining immune function. It is the main component of white blood cells and antibodies. Insufficient protein intake makes it impossible to produce enough white blood cells and antibodies, and immune function will decline. Therefore, intake of high-protein foods can help improve immunity, such as fresh meat, fish, eggs, dairy products and other foods.
Vitamin A is related to cell integrity and can help cells fight oxidation. If the body is deficient in vitamin A, the size of the thymus and spleen will be reduced, and the relative vitality of immune cells will also decrease. Therefore, intake of enough vitamin A can increase the vitality of immune cells and increase the number of immune cells. Liver, eggs, milk, carrots, cabbage, spinach, pumpkin and other foods contain more vitamin A.
Vitamin C can protect cells, enhance the activity of white blood cells and antibodies, and stimulate the body to produce an active substance related to immune function-interferon, which can destroy the virus and reduce the loss of white blood cells. Therefore, when vitamin C is deficient, the probability of successful bacterial and virus invasion will increase, and infectious diseases may be easily obtained. Vitamin C supplementation can be more citrus, tomatoes, green peppers, strawberries, cabbage, potatoes and other foods.
The function of vitamin E is to capture free radicals that damage cells, protect the integrity of cell membranes, and increase the number of antibodies. Vitamin E is rich in olive oil, egg yolks, lettuce, peppers, milk, wheat bread, cabbage, peanuts and other foods.
B stress vitamins are related to the production of antibodies and white blood cells in the body. Lack of B vitamins will affect the number of lymphocytes and the production of antibodies, and also cause the atrophy of the thymus. Therefore, children with weakened immunity can consume more foods of this type, such as meat, green leafy vegetables, and whole grains.
Enzymes related to immune function are often composed of trace minerals. The intake of various trace elements must be ensured in order to make the child's immune system stronger as soon as possible. Trace minerals are found in foods such as seaweed, green algae, wheat grass, whole grains, fruits and vegetables.
Let's see how your immunity is?
If you have more than 3 of the following questions, you must pay attention to enhancing your immunity.
Easy to catch a cold: catch more than 4 colds a year.
Tired easily: often feel tired, can't lift the energy, easily distracted-even if you sleep more than 9 hours a day.
Poor healing ability: Wounds heal more slowly than normal people and are prone to infection, or bruises disappear particularly slowly after being hit.
Weak stomach: easy to suffer from gastrointestinal diseases. For example, when eating out, it’s okay for others to eat the same food, but your stomach hurts, or even vomiting and diarrhea.
Mouth ulcers and gums often bleed.
Poor skin, love hair loss: rough and dull skin, soft hair easy to lose hair
Rhinitis and asthma recurrent: Rhinitis and asthma have repeated attacks, and the lung function is weak.
Sweat easily: sweat when staying, or sweat as soon as you exercise, sweating more than others with the same amount of exercise.
Not tolerant to cold and heat: This kind of people are more afraid of cold or heat than ordinary people. The most obvious thing is that the temperature drops a little. Many people are afraid of cold and clothes without adding clothes.
Herd immunity: the resistance of the population to the invasion and spread of infectious disease pathogens, which is reflected by the proportion of the population with immunity in the population. When most people in a group are immune to a certain infectious disease, not only will they not develop the disease, but also herd immunity will provide indirect protection for those who do not have immunity. Therefore, when the proportion of the immune population in the population decreases, that is, herd immunity When it decreases, the susceptible population will greatly increase, and the incidence of infectious diseases will increase accordingly; when the population immunity increases, the number of people infected in the population decreases, and the possibility of susceptible people being infected will also decrease. , Thereby reducing the incidence of infectious diseases.
