The Mid-Autumn Festival is approaching, the weather is not too cold and not too hot, it is a good time to travel, so, are you ready to travel? Autumn is the high incidence of allergic diseases, allergic friends travel should be the first to prepare for: need to be alert to the occurrence of allergies, such as pollen allergy (especially in the summer and fall season to the grasslands, mountainous areas), dust mites, mold allergies (accommodation hotels), food allergies, and so on. People may ask the following questions: 1. Fall is the time for fruiting, no pollen, right? A: People think that spring is the season to bloom, and in the fall season it’s time to bear fruit, no pollen. In fact, the summer and fall season is the flower blooming season of weeds, such as artemisia, pulling seedlings, every year at the end of August and early September there are a large number of weed pollen drift. This pollen can spread with the wind and drift hundreds of kilometers away. Even if people do not touch or go near these flowers, they can still experience allergic symptoms. Of course, if you go to the grasslands or mountains during this season, the allergy symptoms will be even worse. 2. What are the symptoms of pollen allergy? A: Pollen allergy most often causes allergies in the five senses, manifesting as itchy nose, itchy eyes, itchy ears, itchy palate, itchy throat, continuous sneezing, sneezing 5, 10 or even more sneezes in a row, flowing a lot of watery nasal discharge, nasal congestion. Severe allergies in the lower respiratory tract, manifested by coughing, wheezing, dyspnea, breathing can be heard whistling like “squeak – squeak -” sound. Wheezing at night, especially in the middle of the night, the early hours of the morning, when the seriousness of lying down, sitting up and leaning forward in order to gasp for air, very much affect the quality of life. 3.What measures should be taken for the above situation? A: If you have pollen allergy, the first thing you should do is to choose the right time and place to travel, and try not to go to the grasslands or mountains in summer and fall; if you have to go, you need to take strict protective measures, such as wearing masks and windscreen; at the same time, you need to carry anti-allergy drugs, such as cetirizine, loratadine, and salbutamol aerosol, etc, so as to be prepared for any problems. 4. Shouldn’t I be allergic if I stay in a hotel? A: Staying in a hotel may also cause allergies. There are a lot of dust mites on the beds and bedding in hotels, especially in the carpets; if the room is dark and damp, there will be a lot of mold. People who are allergic to dust mites or mold will immediately develop allergies when they enter such a room, manifesting themselves in sneezing, runny nose, and even coughing and wheezing. In this case, you should rush out of the room to get fresh air, and the symptoms can be gradually relieved. If you have spare drugs to take in time. 5, traveling outside will have a lot of food, inevitably make people can not help but want to taste fresh. So food allergies? A: Food is the most common allergen and often causes severe allergic reactions such as anaphylaxis. If you are already aware of allergic foods, you should strictly abstain from eating foods that contain allergenic food ingredients when traveling. Some people may only be known to have respiratory allergies and not expect to have food allergies as well. For example, a person with dust mite allergy may be allergic to shrimp or crab, and a person with pollen allergy may be allergic to a variety of fruits and vegetables. Because allergies are caused by specific proteins, and some pollens or foods have the same or similar proteins between them, cross-reactivity can occur. This is something that people with allergies need to be very aware of. For some novel, not eaten seafood or vegetables and fruits, do not eat easily, otherwise, may be induced by cross-reaction allergies. 6.Is there any way to improve allergy? A: Allergen-specific immunotherapy is recommended by the World Health Organization as “the only treatment that can influence the underlying mechanisms of allergic diseases and thus change their natural course”. It can improve allergies to a certain extent and gradually increase the level of tolerance to allergens. The method is to expose allergy sufferers to the allergens to which they are sensitized in small increments. This treatment is therefore allergen-specific immunotherapy, which presupposes that the allergens must be identified, otherwise immunotherapy is not possible.
