People can mobilize their immune system as much as they can to ensure that their body is in a “very healthy” state. If the immune system is strong, if infected with a virus, the virus will be minimized. In this regard, experts recommend some ways to enhance immune function in a short period of time: 1, increase the absorption of antioxidants. Antioxidants are chemicals found in foods that can strengthen the immune system. You can boost your immune function by taking some antioxidant supplements: – Take 1000 international units of vitamin E daily. There are two forms of vitamin E: d-vitamin E and dl-vitamin E. d-vitamin E is the natural form and can be absorbed by the body more quickly. a. 1,000 mg of vitamin C per day. You can also get vitamin C by consuming two citrus fruits per day. b. Carotene, take no more than 10,000 international units per day c. Selenium, 200 mcg per day d. Zinc, no more than 500 mg per day e. Lipoic acid, 50 mg per day f. Glutathione, 50 mg per day 2. Drink green tea daily because it contains high amounts of antioxidants flavonoids and theophyllic acid. Eat more tomatoes and other red and dark fruits. 3, do not do strenuous exercise during this period. Because strenuous exercise can depress the immune system function (immune system function related to upper respiratory tract infections). If you are already in the habit of exercising regularly, you can do some light or moderate exercise during this period. 4. Make sure you eat enough carbohydrate foods, such as rice and other starch-rich foods. Because carbohydrates are the most important food for immune cells. 5, ensure enough sleep every day, do not put yourself under tension and stress. Anxiety, tension can affect the body’s stress hormones, thus suppressing the body’s immune function. 6, wear a mask. Although not 100% prevention of infection, but can play a role in reducing the chances of being infected.
