Winter is coming. How can we prevent the occurrence of colds?

　　Winter is coming, how do we prevent the occurrence of colds? I think this is a question that many people want to ask. Due to the cold and dry climate in winter, people are easily susceptible to cold viruses, which makes many people complain. The best way to prevent colds is to increase immunity. The following 10 tips can easily enhance immunity and prevent colds. Hope it helps everyone!

　　1. Get a good sleep. Poor sleep is related to reduced immune system function. T cells in the body are responsible for dealing with viruses and tumors. If you don't get enough sleep, the number of T cells will decrease, and the chance of getting sick will increase. But is it necessary to sleep for 8 hours? This is not necessarily the case, as long as you wake up in the morning and feel refreshed.

　　2. Exercise for 30 minutes a day. Three studies from Appalachian State University in the United States pointed out that after exercising for 30 to 45 minutes a day, 5 days a week for 12 weeks, the number of immune cells will increase, and the resistance will also increase accordingly. Exercise is all you need to get your heart rate up, and a walk after dinner is perfect. If it is too intense or lasts longer than an hour, the body will produce some hormones that suppress the activity of the immune system.

　　3. Massage Massage relaxes the body and reduces stress hormones (such as adrenocortin, which can cause damage to the immune system). One study found that after receiving 45 minutes of massage every day, the number of immune cells increased and immune function was significantly improved after one month.

　　4. Eat some ginseng. Experts point out that ginseng contains ginsenosides, which can strengthen immune function. However, experts recommend taking two 100 mg capsules containing 4% ginseng glycosides every day instead of taking ginseng tablets directly.

　　5. Take 200 mg of vitamin C and 200 international units of vitamin C every day. Taking 200 to 500 mg of vitamin C every day can help the body develop resistance. Experts point out that the number and vitality of the body's weapons against external aggression, including interferons and various immune cells, are related to vitamin C.

　　As long as you take 200 international units of vitamin e every day, you can strengthen your ability to fight infectious agents. For people over 65 years old, after taking vitamin E for 8 months, their immune response improved significantly and returned to the level equivalent to that of a 40-year-old.

　　6. Do not drink more than one cup a day. Alcohol will inhibit the B cells that produce antibodies and increase the chance of bacterial infection. Therefore, experts recommend that even though drinking wine may lower your cholesterol, you should not exceed one cup a day.

　　7. Do not use antibiotics together. Colds are caused by viruses. There is news that taking antibiotics is not only ineffective, but may even reduce the hormones responsible for the immune system in some patients. Do not take antibiotics unless you are sure you have a bacterial infection (usually phlegm or nasal discharge will turn yellow or green).

　　8. People who have a lot of close friends are not only less likely to catch colds, but also have 20% better immune function than introverts. Studies have shown that good social relationships can help fight stress, reduce stress hormones, and affect immune cell function. But interacting with too many people can also become stressful. Don't force yourself. A few close friends are much more important than a bunch of casual acquaintances.

　　9. Laugh often and participate in artistic activities. Laughter can reduce stress hormones. It is said that laughter can significantly increase interferon, stimulate immune function, and immune cells become more active. If you think you lack a sense of humor. You can watch more comedies and funny cartoons, think about the plots when you are nervous, and learn to face the situation at hand optimistically. Music can increase antibodies against infection and cancer. No matter what kind of music you like, listening to it can stimulate healthy physiological responses. Swedish research also shows that people who frequently participate in recreational activities (such as attending concerts, going to museums to see exhibitions, and watching football games) generally live longer than their colleagues who stay at home. These methods of maintaining health are easy, enjoyable and don’t cost a lot of money. In the new year, take action with your family and friends!

　　10. Spend 5 minutes a day daydreaming. Take 5 minutes a day to daydream while taking a deep breath. Let pleasant pictures drift through your mind, which can increase the number and activity of immune cells. A professor at the University of Texas in the United States pointed out that people who engage in such activities have reduced immune system depletion because of reduced stress.

　　When you catch a cold, you must pay attention to your diet. You must be more careful in this aspect and do not eat the wrong things, otherwise it will cause great harm to your body.
