Reasons for low immunity What is immunity? Immunity is the body's own defense mechanism, and it is the body's ability to identify and eliminate any foreign body (virus, bacteria, etc.). Invade from the outside, deal with the aging, injury, death and degeneration of your own cells, and identify and deal with mutant cells and virus-infected cells in your body. Modern immunology believes that immunity is a physiological response of human body to recognize and reject "dissidents". It is the immune system that performs this function in the human body. Therefore, immunity is one of the most critical factors to measure a person's health index. If a person's immunity is too low, it will lead to various diseases, which is not conducive to health.
So, there are several reasons for low immunity:
1, overworked
Lack of sleep, the body can not get enough rest, leading to the body often feel tired and weak, which will affect endocrine and the entire immune system. In the long run, immunity will decline. Be careful not to drink coffee, wine and so on. Before going to bed, create a quiet sleeping environment for yourself.
2. Psychological stress.
Emotional instability, long-term depression, depression, etc. , will affect people's autonomic nervous system, causing more diseases.
3. Insufficient exercise
As the saying goes, life lies in exercise. Insufficient exercise, which leads to the inability to keep up with physical strength, is one of the fundamental reasons for low immunity. Once sedentary people start exercising, they will feel less tired and full of energy.
4, unbalanced diet
Long-term picky eaters, partial eclipse, irregular diet and disordered diet will affect the nutritional supply of the whole immune system and lead to low immunity.
Besides, I like drinking coffee and eating sugar. , will make the blood sugar level ups and downs, easy to produce fatigue. So pay attention to eat more vegetables, fruits and vegetables, lean meat and so on.
5. Overprotection
Excessive protection will keep the body in a specially treated environment, just like flowers in a greenhouse. Once exposed to harsh environment, it has no ability to fight against it.
6. Physical aging
Physical aging is a normal phenomenon and one of the fundamental reasons for low immunity.
In addition, the abuse of antibiotics and excessive use of antibacterial soap will also lead to the decline of immunity.
The performance of low immunity is the body's own immune ability and the body's ability to resist external diseases. However, modern people are busy with work and life pressure, and few people pay attention to their immunity. They think that only children need to improve their immunity. In fact, adults also need to improve their immunity at all times. So, what are the manifestations of low immunity?
1, the cold keeps recurring.
People with low immunity, as long as the weather changes slightly, whether it is cold or hot, will start sneezing if they don't add or subtract clothes in time, and then catch a cold all the time, which has become a common occurrence. And once you catch a cold, it always takes a long time to recover, and it will recur.
2. It is particularly easy to feel tired.
When you are listless at work, you will feel very tired if you do something a little. After going to the hospital for examination, nothing was found. After a period of rest, your energy is relieved, and after a period of relief, fatigue appears again, indicating that your immunity is low.
3, the stomach is delicate and loves to get sick
If you eat out, everyone else is safe and sound, only you vomit and diarrhea, which means that there is something wrong with the self-protection function of your stomach and intestines, which is also a sign of low immunity.
4. Susceptibility to infection
When your colleagues or family members catch a cold, you are always infected, which means that you are always hurt by infectious diseases, which proves that your resistance is problematic.
5. Their wounds are susceptible to infection.
If any part of your body is accidentally scratched, normal people can recover in a few days, but your wound is always red, swollen and purulent, which takes a long time to recover, indicating that your resistance has decreased.
How to deal with low immunity? Low immunity makes us vulnerable to viruses, bacteria and other attacks, leading to diseases. Therefore, the most fundamental way to solve the low immunity is to improve the immunity of the body to avoid the occurrence of diseases. So, how can we improve immunity?
Maintain a balanced nutrition.
1) Eat more protein.
Protein is the material basis of human immune defense function, so we should eat more abundant food in protein in our daily life.
2) Drink more tea
Tea contains a chemical called "theanine", which can enhance the body's ability to resist infection. In addition, theanine can also mobilize human immune cells to resist viruses, bacteria, fungi and so on.
3) Vitamin supplementation
Vitamin C can inhibit the synthesis of nitrosamines, promote the formation of antibodies, enhance the phagocytosis of white blood cells and enhance the body's resistance. Vitamin A has protective effect on respiratory tract and gastrointestinal mucosa. Lack of vitamin A will reduce the body's antibody response, leading to a decline in immune function, and bacteria and viruses will take advantage of it.
4) Eat more animal livers.
Animal liver is rich in many substances that help to promote immune function, such as folic acid, selenium, zinc, magnesium, iron, copper, B6, B 12 and so on.
5) Drink plenty of water
As the saying goes, water is the source of life, so water is inseparable from our lives, especially immunity. If the body is short of water at ordinary times, the immunity will be reduced. Drinking more water at ordinary times can keep many of our mucous membranes moist, so as to take away germs.
Maintain mental health
A person's immunity has a lot to do with his mood. It is found that negative emotions such as hostility, sadness, loss and sadness will lead to the decline of human immunity, while cheerful and lively personality and happy emotions will improve human immunity. Because spiritual pleasure, sadness and distress can produce two different biochemical processes, sadness and sorrow will change the hormone secretion of the body, cause physiological dysfunction and weaken the immunity of the body; Keeping an optimistic attitude can keep the human body in the best condition.
Therefore, treat the stress in life correctly, regard it as an inseparable part of life, learn to decompress moderately, and ensure a healthy and good mood.
Pay attention to the combination of work and rest
1) Get enough sleep
The normal operation of human biological clock is the guarantee of health, and the "wrong point" of biological clock is the beginning of sub-health. After people go to sleep, all kinds of processes that are conducive to enhancing immune function begin immediately. If you sleep less than 7 to 8 hours a day, your chances of getting sick may increase. Because long-term lack of sleep will cause damage to the body, including decreased thinking ability, decreased alertness and judgment, and low immune function.
2) Exercise regularly
Modern people are keen on city life, busy with their careers, and have less and less time for physical exercise. Strengthening self-exercise can improve the body's resistance to diseases. Regular moderate-intensity exercise can enhance the function of the immune system, because physical exercise can relieve emotions and reduce stress.
What good garlic to eat with low immunity?
Garlic contains allicin, which can resist infection and bacteria. Experimental research shows that eating garlic can reduce the chance of catching a cold by 2/3. People who chew garlic regularly are also less prone to colon cancer and stomach cancer. Therefore, it is recommended to eat two cloves of garlic raw every day and add some minced garlic when cooking.
tomato
Tomatoes contain a variety of powerful antioxidant factors, such as lycopene, carotene, vitamins E and C, which can improve the baby's immunity, repair damaged cells and protect cells from damage. Experiments show that when people eat tomato juice for two weeks in a row, lycopene in the body will increase obviously and the immune function of T lymphocytes will be enhanced. It's best to cook tomatoes a little and add a little olive oil to make lycopene more easily absorbed by the human body.
watermelon
Mature watermelon also contains a lot of powerful antioxidant glutathione, which has the function of moisturizing and refreshing. Because it helps to enhance the function of the immune system and can resist infection. Glutathione is located in red soil near melon skin.
cabbage
Cabbage is another plant rich in glutathione (with immune enhancement function). Adding all kinds of Chinese cabbage (white, purple and medium) to the soup and stewing slowly can release antioxidants into the soup and increase the nutritional value of food.
Cauliflower
Broccoli contains vitamin A, vitamin C and glutathione, which can improve human immunity.
Fish and shellfish
Fish and shellfish are rich in selenium. Supplementing enough selenium can increase the number of immune proteins, thus helping to clean up the influenza virus in the body. Selenium mainly comes from seafood such as oysters, lobsters, crabs and clams. Omega-3 in Atlantic salmon and other fish can help the blood to produce a large number of anti-influenza cells, and also help to improve human immunity.
Oats and barley
Oats and barley both contain β -glucan with antibacterial and antioxidant effects. Eating oats and barley can enhance immunity, accelerate wound healing and help antibiotics play a better role.
malt
Malt is a part of wheat seeds, which is rich in nutrients, including zinc, antioxidants, B vitamins and other important vitamins and minerals. Malt also contains cellulose, protein and unsaturated fat.
