For those living with allergic rhinitis or asthma, caring for the environment where you live can be part of a routine to prevent flare-ups. Dust, mites, mould, and other agents present on surfaces, fabrics, and objects can contribute to respiratory discomfort. Beyond medical treatment, some cleaning and organisation habits can help keep your home more comfortable.

"Patients often focus only on medication but forget that successful control of rhinitis also depends on reducing allergen exposure in the environments where they sleep and live. Proper cleaning of fabrics and surfaces can help," explains Dr Brianna Nicoletti, allergist and immunologist.

Below are some tips for maintaining a healthy home and reducing dust and mites.

1. Pay special attention to the bedroom

The bedroom deserves frequent care, as it's a space where you spend extended periods. Avoid excess objects that accumulate dust — such as fluffy rugs, too many cushions, and stacks of books. Keeping surfaces clearer also makes cleaning easier.

2. Wash bedding regularly

Sheets and pillowcases should be cleaned frequently to reduce dust, skin cells, and mites. The specialist recommends maintaining a regular washing routine and following temperature recommendations on each item's label whenever possible.

3. Keep rooms well-ventilated

Opening windows during the day promotes air circulation and helps control humidity. Natural light also contributes to a fresher environment.

4. Watch for moisture and mould

Leaks in bathrooms, kitchens, and other areas should be fixed as soon as possible. Mould can contribute to respiratory symptoms, so controlling humidity is an important measure for those with respiratory sensitivities.

5. Prefer cleaning methods that reduce dust dispersion

When cleaning surfaces, mattresses, upholstery, and curtains, it's important to avoid simply spreading dust around. Steam cleaning is an alternative. According to Vinícius Marin, sales director at Kärcher Brasil, cleaning can also be an act of care. Steam acts at high temperatures and can be used on different surfaces, helping remove dirt and allergens without the need for chemicals in certain applications.

"Steam equipment can reach crevices and fabrics where regular cleaning doesn't always reach. For people with sensitive airways, reducing exposure to volatile chemicals can also be an important precaution," adds Dr Brianna Nicoletti.

6. Pay extra attention to frequently used items

Toys — especially those that come into direct contact with children's hands and mouths — also need regular cleaning. The same applies to frequently touched surfaces and objects. The chosen method should always be appropriate for the item's material.

7. Reduce dirt brought in from outside

Doormats at the entrance and the habit of removing shoes when arriving home can help reduce pollutants and external dirt entering the house. This simple measure complements the overall cleaning routine.

Quick summary

The bottom line: Reducing allergens at home goes beyond medication — it's about creating an environment that supports respiratory health. Regular cleaning, good ventilation, and smart habits can make a real difference in managing rhinitis and asthma symptoms.
