1.What dust control measures should be taken for patients with allergic rhinitis or asthma? Dust and mites are the most important allergens causing asthma, and it is crucial for asthma patients who are allergic to them to pay attention to dust and mites in their daily life. Even if the patients are not allergic to dust and mites, they should actively dust and mite control: because asthma patients are characterized by high airway reactivity, any stimulation, including inhalation of more dust, can easily lead to asthma attacks. The interior furnishings should be simple, and some people have too much furniture in their homes. And bulky. It is not easy to move and clean, so it is easy to leave a dead spot. Develop the habit of “wet work”, do not use a broom to sweep the room, sweep the bed, sweep the floor, and do not use the duster to dust the furniture. In fact, the duster can only play the role of dust moving, and can not remove the dust. Allergic rhinitis or asthma patients are best not to clean their own indoor hygiene, if you want to clean indoor hygiene should be careful to bring a mask. Try not to stack a large number of books in the bedroom, and do not hang paintings and calligraphy, because the dust on the book is very difficult to remove. It is recommended to keep the books that are not often read separately, and it is enough to put some commonly used books indoors. Carpets are harmful to asthma patients. Carpets are easy to hide dirt and inconvenient to clean, and are easy places for fungus and mites to breed. Air conditioners for sensitive people should be fully wiped before starting. Otherwise, after a winter, the dust stored in the air conditioner will be scattered with the cold wind, the electric fan is still a good and inexpensive appliance, but also often wipe the fan blades. In the winter of each year before opening the heating should be scrubbed heater, otherwise it is easy to smell. Try not to place large TV sets in the bedroom. Because the TV can form a large magnetic field, so that the organic dust particles with an electric charge swimming in the direction of the TV. If you open the back cover of the TV, you will find a lot of dust, which is an important allergen. The kitchen should be airtight between the kitchen and the bedroom, and there should be good ventilation in the kitchen (such as a range hood), because frying fumes are very strong asthma-causing agents. 2, some other considerations: inappropriate decoration is very bad for asthma patients. This is because adhesives and paints are very strong chemical asthma-causing substances in renovation. If you renovate your home, it is recommended that you fully open the windows before moving in and wait until there is no smell before moving in. Asthma patients should preferably not keep pets, let alone indoor pets, because a significant number of asthma patients are allergic to pet hair and dander. Cats have the habit of licking their fur so that allergens in their saliva will adhere to the fur and when the patient comes in contact with the cat. The allergen will be inhaled. In recent years, there has been an increase in the number of pigeons and birds. Some people seal up their balconies for raising birds. Allergens from bird hair, bird droppings and parasites on the bird’s body can be inhaled and can cause allergic alveolitis in addition to asthma. Keeping flowers indoors is not a good idea either. There are many mites and fungi in flower fertilizers, and some ornamental flowers can give off a strong scent that can also trigger asthma. It should be noted that. Indoor ornamental flowers generally do not cause pollen allergies, because ornamental flowers are mostly insect-borne flowers, while those that cause hay fever are mostly wind-borne flowers. Do not store food and food in the bedroom, because food is prone to mites and fungi, and food residues are feed for cockroaches and mites. Smoking should be strictly prohibited indoors. Active and passive smoking are both detrimental to patients. Insecticides should be banned indoors. Especially dichlorvos, many asthma patients inhaled can immediately cause asthma attacks, the use of other types of insecticides should also be extra caution. Indoor use of mosquito incense. If you want to use mosquito incense, should choose a less irritating mosquito incense, such as electric mosquito incense. Be careful with air fresheners indoors because many air fresheners contain a variety of fragrances, some of which can trigger asthma attacks.
