As spring and summer change, it seems as if nature is putting on a gorgeous "dress-up" show. Flowers are in full bloom and everything is reviving, but in this colourful season, many people's bodies are starting to "revolutionize" - allergies are acting up frequently. Sneezing like a series of cannons, eyes itchy and want to rub, the skin is red and itchy, as if the spokesman for the "itch".

Allergies may seem commonplace, but there is a lot of "mystery" behind them. People often think that allergies are just a few red dots on the skin or something wrong with the food you eat, but the truth is much more complicated than that. The symptoms of allergy are also varied, ranging from mild redness of the skin to severe shock and even life-threatening symptoms. They think that as long as they endure, the allergy symptoms will subside naturally. This kind of thinking is like treating allergies as a "little cold" and thinking that if you just carry on, you'll get over it.

His eyes and nose always protested in unison, itching unbearably, and his tears and snot were like open floodwaters that could not be stopped. Over the years, Ross knew his allergens by heart and was prepared for the "old problem" of pollen allergies. When spring comes, he is like a warrior about to go to war, all armed tightly, afraid of a trace of pollen in the nostrils or eyes. However, recently Ross has encountered an unprecedented "new enemy". Originally thought it was just pollen allergy aggravation, but I did not expect the forehead, arms and neck to appear as a grain of red rash, like being mercilessly branded "allergy" marks. These rashes are red and itchy as if mocking his many years of "anti-allergy" experience. Ross couldn't help but mutter in his heart: could this pollen allergy be "upgraded"? With a belly full of doubts, Ross found a doctor. After a careful examination, the doctor found that these rashes are concentrated in the exposed parts of Ross's skin, which can not help but think of another possibility - light allergy. Sure enough, the results of the photosensitivity test confirmed the doctor's suspicion that Ross was unusually sensitive to medium-wave ultraviolet UVB rays. Now, Ross's "anti-allergy" battle has a new task - sun protection. Every time he goes out, he has to be like a knight who is about to go on a battlefield, all over the body is coated with thick sunscreen, wearing a sun hat and mask, afraid of a ray of sunshine through the cracks to hurt themselves. At the same time, the doctor also prescribed him some anti-photosensitizing drugs to help relieve his symptoms.

If you also suffer from allergies, you may want to master some self-checking tips to become the guardian of your health. To find the root cause of allergies, you have to be like a detective and carefully collect clues, from medical history to condition, every detail should not be spared. Time, seasonality, occasions, weather, and even the details of food, housing, living and mood swings can be key clues.

Allergens are like cunning criminals who invade our bodies in three ways: inhalation, ingestion and contact. To bring these "criminals" to justice, we need to use some high-tech means. Blood tests, like advanced DNA testing, can pinpoint inhalant and ingested allergens, while skin patch tests are like specially designed decoys to keep contact allergens at bay. These allergens are like criminal gangs with different modus operandi and characteristics. For some people every pollen season "hits”, then tree pollen, and grass pollen, these "suspects" should be focused on screening; some people use long unused air conditioning after allergy symptoms, then mould allergens are like that hidden in the dark! The "real culprits" must be screened.

Do not underestimate allergies, they may bring more harm to the body. Therefore, in the face of allergies, we must not take it lightly, let alone "get over it". Only by taking timely measures can we win the battle against allergies.
