Muscular men can catch a cold, too. How can we improve our immunity?

Teach you 1 tricks to improve immunity

The immune system can prevent bacteria and viruses from entering the human body and help patients recover. It is closely related to the endocrine system and nervous system, and people's lifestyle and emotions directly affect the immune function. Dr. Lee Burke of the University of California School of Medicine wrote on the website Embodiment: "Years of research have shown that you can live a healthy and happy life as long as you pay attention to some simple details of your life." Here are 1 ways to scientifically improve immunity:

1. Spend more time with friends

When you are with friends, your immune system will be in a good state because you feel friendship and social recognition. In order to prove this point, the researchers of the Paris Center for Physical and Mental Health exposed the participants to the cold virus, and then the researchers tracked and monitored their social interaction. It turns out that people who spend more time with friends, family and colleagues are less likely to catch a cold. At the same time, physical contact such as hugging and touching can also make human immune cells more active.

Second, listen to your favorite music

Listening to music can also activate your immune system, but only if you really like it. "The same piece of music sounds like Yue Xian to some people, and it may be noise to some people." Dr. Burke said, "The key is to choose music that can soothe your heart." Good music, like food and sex, can stimulate the pleasant part of the brain, thus improving immunity.

Third, reduce noise

Noise not only harms people's hearing, but also causes muscle tension, rapid heartbeat, vasoconstriction and digestive system discomfort-this is the same as the body's reaction when it is scared or stressed. If people are exposed to noise for a long time, it will lead to adverse changes in blood pressure, cholesterol level and immune function. A study by Cornell University in the United States found that women who work in noisy environments release more adrenaline than women who work in quiet offices and are more likely to suffer from heart disease. The car flute, dog barking and other sounds that make people feel uncontrollable are more harmful to the human body. Therefore, people should try to control the sound around them, even if they wear headphones, or ask restaurant owners and gym managers to turn down the volume of the stereo.

Fourth, keep a positive attitude

The immune system will be hinted by thoughts and feelings, so we should keep a positive attitude. Researchers at the Mayo Clinic in the United States found that optimists live 12 years longer than pessimists when they are young. Recently, Anna L. Masland, a psychologist at the University of Pittsburgh Medical Center, also found in her research that people who are negative, depressed and easily feel stressed have much weaker resistance to hepatitis virus than their optimistic peers.

5. Reasonable diet

Lack of any kind of nutrition will lead to recurrent and long-term diseases. When people feel hungry, the body will secrete adrenaline; If you lose more than 85g per week, T cells that resist diseases and foreign viruses will be inhibited. In this regard, experts suggest eating some foods containing unsaturated fatty acids, taking enough protein, eating more fruits and vegetables, and drinking more fruit juice and boiled water. However, the effect of health care products that claim to improve immunity is not obvious.

6. Laugh loudly

Anger and sadness can damage health, while laughter has the opposite effect. Laughter can make immune cells more active. To prove this statement, Burke showed students a funny video and measured their immune system response. It turns out that even hearing a humorous joke can improve immunity. In addition, laughter can promote circulation and digestion, lower blood pressure and relieve muscle tension.

VII. Use your brain more

Active thinking activities can improve your immunity. Marianne Diamond, a neuroscientist at the University of California, found in her research that playing bridge can stimulate the activity of immune cells. Her research reveals for the first time that there is a close relationship between the parts of the brain responsible for planning, memory, judgment and abstract thinking and the immune system. Diamond said: "Any thinking activity, as long as it is applied to the intellectual function of the brain, will be good for immunity."

Eight, more activities

Regular and long-term moderate exercise can enhance the body's resistance. Burke said: "Physical exercise is not only good for cardiovascular system, but also good for improving mood and reducing stress." However, the intensity of activities should be appropriate, and if you feel tired and beyond your usual tolerance, you should adjust it in time.

9. Learn to relax

Stress will make the human body secrete steroid hormones and adrenaline, which will slow down the immune system. This explains why people are particularly prone to catch a cold when they are under pressure, such as facing the final exam and emotional crisis. In addition, anxiety caused by stress will also reduce human resistance. Regular practice of relaxation techniques, such as aerobic exercise and gradual relaxation of whole body muscles, can inhibit the release of stress hormones and enhance immune function.

1. Turn off the light

Melatonin, a disease-fighting hormone, is produced in the dark. Lack of sleep or being in the light for a long time at night will reduce the release of melatonin and increase the secretion of estrogen, which makes it easy to get breast cancer. Several recent studies have shown that the proportion of women who work at night is as high as 6%, and the proportion of women who like to make light in the bedroom bright is even higher. The proportion of blind women suffering from breast cancer is 2%-5% lower than that of normal people. Even weak light sources such as bedside alarm clock and nightlight can inhibit the release of melatonin. Therefore, the darker the bedroom, the better.
