In fact, a study by the American Journal of Preventive Medicine shows that the improvement of the home environment , reduces exposure to allergens or irritants and can improve the quality of life of asthma patients. The report also shows that the number of days of asthma symptoms and the number of days of absenteeism are reduced as a result of improving the home environment. Therefore, self-care at home has a real effect on improving the quality of life and productivity of children and adolescents.

Dust mites

You can choose allergen-infiltrated or dust-resistant pillows and bedspreads, wash sheets with hot water above 60 degrees. If hot water is not available, then use cold water, detergent and bleach as it can achieve almost the same efficacy. Remove old carpets and use a dehumidifier or central air conditioner to reduce the humidity in your home to less than 60%. Also, avoid lying on upholstered furniture or sleeping on it. Please also reduce the number of stuffed dolls on your child’s bed and wash them weekly.

If you can, try to clean up your home once or twice a week by someone outside your home. Do not come near for a short period of time when the outside cleaning staff cleans the room and after cleaning. If you are cleaning yourself, use a dust mask and a vacuum cleaner with a HEPA filter or double dust bag.


Protect people who are sensitive to mold by removing mold from hard, porous surfaces; discarding moldy materials (e.g. carpets, ceiling tiles); and finding the source of moisture that causes mold growth. This includes repairing leaking faucets, pipes and other water sources.


Remove food and water, clean the table and floor, seal the trash bin, store food carefully, use bait to eradicate cockroaches. Also, seal cracks and holes at home to prevent cockroaches from approaching. Be careful not to expose food or garbage, using toxic baits, boric acid, and traps to catch cockroaches are better than using chemical pesticides.

If a spray is used, the home should be fully ventilated, and asthma patients should not go home until the smell disappears. In addition, care should be taken when using these methods so that young children at home will not be exposed to cockroach drugs and toxic substances.


Not keeping pets at home is the most effective way for sensitive patients to reduce allergens, if not, then the alternative is not to keep pets close to the bedroom, which can reduce the allergens by nearly 5 times. The patient’s bedroom door should be kept closed and upholstered furniture and carpets should be cleared of pet’s fur removed. An efficient air purifier can also reduce dander in the air.

If possible, choose odorless and fragrance-free personal cleaning and care products.
