Vitamin A plays an important role in the process of connecting skin tissue. The best way to supplement vitamin A is to obtain beta carotene from food. Sweet potatoes are the fastest way to obtain this nutrient. They are rich in beta carotene and are low in calories.

Tea: fights bacteria and prevents influenza. Immunologists at Harvard University have found that people who drink five cups of black tea a day for two consecutive weeks will produce a large amount of anti-viral interferon in their bodies. The content is 10 times that of people who do not drink tea.

Adding some onions and garlic when simmering chicken soup can make the effect more obvious.

Beef: Supplement zinc to enhance immunity. Zinc is very important in the diet. It can promote the growth of white blood cells and thus help the body protect against harmful substances such as viruses and bacteria. Even mild zinc deficiency can increase the risk of infectious diseases. Beef is an important source of zinc for the human body, so in winter, appropriate beef supplements can not only resist cold but also prevent influenza.

Mushrooms: Promote white blood cells to fight infection. Mushrooms have long been used as a food to boost immunity. Now, researchers have found a reason to do so: Eating mushrooms boosts the production and activity of white blood cells, making them more defensive.

Fish and shellfish: Supplement selenium to prevent viruses. British experts have pointed out that supplementing enough selenium can increase the amount of immune proteins, thereby helping to clear the body of influenza viruses. Selenium mainly comes from seafood such as oysters, lobsters, crabs and clams. Omega-3 in fish such as Atlantic salmon can help the blood produce a large number of flu-fighting cells and also help improve the body's immunity.

Garlic: Allicin fights infections and bacteria. Experimental results by British researchers show that eating garlic can reduce the chance of catching a cold by 2/3. People who chew garlic regularly also have a significantly lower chance of colon and stomach cancer. Therefore, it is recommended to eat two cloves of garlic raw every day and add some minced garlic when cooking dishes.

Oats and barley: healthy fiber and antioxidants. Both oats and barley contain beta glucan, a fiber that has antibacterial and antioxidant properties. Eating oats and barley can enhance immunity, speed up wound healing, and help antibiotics work better.

The social circle is too narrow. Friendship can strengthen immunity. The fewer friends a person makes, the more susceptible he is to illness, and even his lifespan is greatly affected.

I owe "sleep debt" on weekdays. Frequent deprivation of sleep time will sharply reduce the number of immune cells produced by the body. People who sleep 7-8 hours a day have only 50% less influenza antibodies in their blood than those who sleep only 4 hours a day.

Always think of the worst in everything. When pessimists view life's misfortunes in a positive light, their physical condition improves significantly

People who drive around all day are sick twice as long as people who like to walk. By doing 30 minutes of aerobic exercise (such as brisk walking) every day, the immune system works more efficiently.

Over-reliance on antibiotics. Taking antibiotics at the first sign of cold symptoms will only make the virus resistant, leading to a more serious infection.

Not easily amused. Laughter can reduce the secretion of stress hormones and increase the number of immune cells. Watching a funny video during lunch break, sharing jokes or comics forwarded by friends are all ways to gain happiness

My friend is a heavy smoker. It's not enough to just quit smoking on your own. The impact of secondhand smoke on health goes without saying.
