Many parents do not pay much attention to the problem of allergies, thinking that their children do not have obvious allergy symptoms, but in fact they do not. Many diseases are closely related to allergies, and proper prevention can improve your child’s quality of life and reduce allergens, starting from daily life. 1. Prevention of pollen allergy The powder of flowers and plants is the most important allergen, with obvious seasonality, spring and autumn are the most pollen season. Go to botanical gardens or parks where flowers and plants are concentrated less often in spring and autumn; or when you go, remember to wear a mask. When you get home, wash off the pollen that falls on your hair and clothes quickly. Especially when there is wind, try to reduce or even avoid outdoor activities. Don’t plant flowers and grass at home, and try to open windows as little as possible during pollen season. Using a humidifier indoors can also effectively reduce the concentration of indoor pollen. Since pollen allergens enter the body through the nasal mucosa and cause allergies, wearing a mask is the most effective way to prevent them. Washing the nasal cavity with water after going out can also reduce the time pollen stays in the nasal cavity and reduce the occurrence of allergies. Washing your face with warm water can also reduce the amount of pollen that enters your body directly through your skin, but it is best not to wash your face with hot water. If you must occasionally go to a park or botanical garden, you can take anti-allergy medication 1 day in advance, and when you come back without symptoms, you do not need to take it continuously; if you have symptoms, you have to take it for 3 consecutive days. In the spring pollen period, the autumn pollen period and winter heat and cold changes and other periods that are prone to allergies, it is necessary to take anti-allergy drugs in advance. 2, prevention of dust mite allergy Dust mites mainly live in the home environment, so the home environment is very important. Bed sheets and other bedding are best used with anti-dust mite material products, and as much as possible, they should be washed once a week with hot water above 55 degrees Celsius. Although taking the sheets to the sun has some effect, it is far less effective than washing them in hot water. Try not to use carpets and tapestries, it is best to have wooden floors in your home, and you can also use some dust mite insecticide. Children’s stuffed toys and curtains may also become the hiding place of dust mites, try not to use fabric sofas, use leather sofas or wood sofas instead. Don’t use curtain cloth either. The cloth tends to attract dust, dust mites, microbes and other allergens from the room. Dust mites need humidity to grow, strengthen indoor ventilation, reduce indoor humidity can also effectively control the growth of dust mites. 3, prevention of microbial allergy Microbial is also a common allergen, mainly occurs in the rainy season. In the early summer and autumn to drink more water and wash your nose often. In addition to reduce the plant pot at home, because the moist soil is the ideal breeding ground for microbacteria. 4. Prevent hair and microscopic dust allergies Pet fur and secretions are strong allergens, especially in cats, and allergens can still be checked at home even after more than a year away from home. In addition, many communities have many pets and the air is filled with fine allergen particles, so many children run around with a runny nose all day, especially a runny mucous nose. The best thing to do is to clean your nose often. Regularly clean the air conditioning filter, easy to accumulate dust appliances and furniture should also be cleaned frequently, the floor should be sprayed with some water mist before sweeping. Stop smoking indoors and do not take your children to public places where people smoke. Allergy prevention tips: (1) Vaccinations for young children with allergies should be done with caution: some vaccines contain special proteins that are likely to cause allergy symptoms. (2) Cold air is also a common cause of allergic rhinitis: children’s noses are sensitive when they encounter temperature changes, and the best way to prevent it is to swim to increase resistance. But before swimming, let the child have a process of adaptation, it is best to let the child first wash his face with cool water, followed by ice water, and then go swimming after the child gradually adapt. (3) Eat less food that can easily cause hair allergies: whether allergens cause allergies, there is a superimposed effect in the body, reducing one allergen can effectively stop the stimulation of other allergies. In addition, you should also let your child exercise moderately and often to strengthen their immunity and prevent them from getting sick at the root.
