1, pollen Spring is the most serious season of pollen allergy, tiny pollen particles will be spread in the air in the process of propagation, and with the flow of air and flying around, and some of them will be inhaled and absorbed by the skin, pollen allergy can lead to respiratory tract infections, conjunctivitis of the eyes and other symptoms. 2. Microorganisms and insects Spring is the season when various microorganisms and insects are rampant. If the body’s resistance decreases, it is easy to be “defeated” by the viruses and bacteria lurking in the body, resulting in illness. As spring is also the season of outdoor activities, so the case of insect bites also often occur, due to mosquito bites leading to papular urticaria is very common. 3, pet fur and secretions You may not think that your own pet’s fur and secretions may also cause allergies. In the spring, animals secrete special sexual secretions for courtship, and these substances and the tiny fibers that remain when they change their fur are allergens to humans. Families with pets should observe themselves more often and disinfect their pets regularly. 4, climate change The climate in spring is variable, the temperature spring temperature is hot and cold, so that sensitive people facial redness, burning. At the same time, the climate is humid, resulting in the slow dispersion of pollutants in the air, so people have more opportunities to come into contact with pollutants, longer contact time, and lead to sensitivity. 5, food Food allergies do not only occur in the spring, but is an important cause of allergies in babies. Parents who find that their children have allergies in the spring cannot ignore food as an allergen. Milk, eggs, seafood, and nutty foods are all likely to cause allergies in babies. How to prevent baby allergies in spring? Keeping away from allergens is the key 1. Within 6 months: milk allergy After babies add complementary foods, they are prone to food allergies. The main manifestations are severe eczema, hives, asthma, nausea, vomiting, weight loss and so on. Follow the principle of “add small amounts, one at a time”, and stop eating in time if there are allergy symptoms. Give your child more fresh vegetables, fruits and green foods. 2. 1 to 2 years old: mainly allergies to complementary foods As the diet structure of children aged 1 to 2 years old continues to be complex, but the organs and functions of the body are considered to be fully developed, they may still be allergic to some foods, so parents should still be careful to gradually add complementary foods. In addition, after children can walk and run, their exposure to the outside environment increases, and the chances of being exposed to some foreign allergens such as pollen, insects, pets and even chemical materials increase greatly. Parents should pay attention to keeping the indoor environment clean, washing and disinfecting baby’s products and toys, especially stuffed toys, and not letting babies go in and out of dusty places and play, avoiding exposure to dust, pollen from flowers and trees, etc. Allergic factors, avoid contact with perfumes, paints, pesticides and other irritants. 3. 3 to 6 years old: inhalation allergy As children grow up, allergies to some foods may be alleviated. After the age of 3, children may have more allergies caused by some external allergens, especially inhalation allergies (such as pollen, dust mites, dust, fungi, animal fur, feathers, cold air, etc.). Clinical statistics show that more than 80% of childhood asthma is triggered by allergies, and nearly 1/2 of children with asthma develop symptoms such as coughing, wheezing and breathing difficulties before the age of 3. Parents should pay attention to reduce their children’s exposure to pollen, stuffed toys, animal fur and other allergy-prone substances, and also improve hygiene at home by frequently changing and washing baby’s sheets, covers, pillowcases and other supplies. It is important to note that the use of disinfectants and germicides should not be excessive, as too much “cleanliness” may cause the baby to lack contact with microorganisms, inhibiting the development of the immune system and triggering allergies.
