    People who are allergic to ultraviolet rays should prioritize eating more foods rich in vitamin C, vitamin E, carotenoids, and niacin, and try to avoid large amounts of photosensitive foods. It is also recommended to eat less alcohol and highly spicy foods to avoid aggravating inflammatory reactions.

    I met a girl who was in college two years ago. During the spring break, my classmates and I went to the countryside to dig wild vegetables. We made a large meal of shepherd's purse dumplings and went hiking for two hours the next day. It turned out that her cheeks were just prone to redness after being exposed to the sun. That time, she broke out in small contiguous rashes all over her face. It was so itchy that she couldn't sleep at night. After going to the hospital, she found out that it was an acute allergy caused by ultraviolet radiation combined with photosensitive foods. It took almost ten years to completely subside.

    There is a saying on the Internet that you should not touch even one bite of photosensitive foods. In fact, there is no need to be too absolute. If your allergies are very mild, you just occasionally feel itchy after being exposed to the sun for a long time, and you do not plan to stay outdoors for a long time that day. Occasionally eating a few bites of photosensitive foods such as fennel and gray cabbage will not be a big problem. There is no need to directly add these vegetables to the forbidden blacklist.

    When it comes to foods that can help relieve allergies, the core is to help the skin resist oxidation and strengthen the barrier. It is equivalent to laying an invisible cushion on the inner layer of the skin to reduce the inflammatory damage caused by ultraviolet stimulation. My skin tends to turn red easily when exposed to the sun. After the summer, I used to grab a dozen plain almonds as a snack every day, along with a kiwi fruit or a few fresh dates. Last month, I went camping at the beach with my friends and spent more than three hours in the sun. Before, it would stay red for at least two or three days and still itch. This time, my cheekbones were a little pink, and I put on a soothing mask at the hotel and it was almost gone.

    Many people don’t know that niacin is also helpful for ultraviolet allergies. It is what we often call vitamin B3. It is found in whole grains and lean beef. It can help stabilize the barrier function of the skin and reduce the release of inflammatory factors after ultraviolet stimulation. I have an old fan before. She told me that she used to have allergies at least two or three times a week after summer, and she would develop small blisters when exposed to the sun. She drank a bowl of unsweetened oatmeal for breakfast every day for more than two months. This summer, she has only done this once, and it was because she forgot to wear a hat and ran for half an hour for takeout at noon.

    Of course, don’t overestimate the role of food. It can only assist in relieving the symptoms. If you are really itching after an allergy attack, you still have to follow the doctor’s instructions and take anti-allergic medicines. Daily hard sun protection (sun hat, sun protection clothing, mask) is the most effective preventive method. There was a girl who took more than ten vitamin C supplements a day to prevent allergies. As a result, she had diarrhea for several days, and her immunity was reduced, which made her allergic reactions more frequent. It was completely worth the loss.
