As winter persists, many of us are staying inside to keep warm and cosy. However, the colder months also bring challenges to indoor air quality, particularly for individuals with asthma and allergies. While most Aussies are aware of our hot and sticky summers, indoor humidity can sometimes be higher during winter due to limited ventilation, condensation, and increased indoor activities. The hidden winter humidity can create ideal conditions for unexpected allergens like dust mites and mould to thrive.

Understanding winter allergens: dust mites and mould

Dust mites and mould are common indoor allergens that thrive in warm, damp conditions. During winter, homes are often sealed to retain heat, leading to reduced ventilation and increased humidity levels. Activities such as cooking, showering, and drying clothes indoors can contribute to moisture buildup, creating an environment that promotes allergens.

Dust mites, found in bedding, upholstery, and carpets, thrive when indoor humidity exceeds 60%, leading to allergen levels that can trigger asthma and allergy symptoms.

Mould also prospers in humid environments. It can grow on various surfaces, including walls, ceilings, and furniture, often going unnoticed until it becomes visible or emits a musty odour. Mould can impact the integrity of organic materials like timber, plasterboard, and insulation, potentially leading to structural damage and costly repairs to your home. Mould exposure can also cause respiratory issues and exacerbate asthma symptoms, so combating mould before it spreads is extremely important.

The importance of managing indoor humidity

Maintaining optimal indoor humidity levels is crucial for preventing the growth of dust mites and mould. The National Asthma Council Australia recommends keeping indoor humidity between 30% and 50% to minimise allergen presence.

Selecting allergy-friendly winter bedding

Choosing the right bedding is essential for reducing allergen exposure during winter. Choose hypoallergenic materials that resist dust mite colonisation, such as tightly woven fabrics. Cover mattresses and pillows in allergen-proof covers to create barriers against dust mites. Regularly washing bedding in hot water (at least 60°C) can also help eliminate allergens.

Heating solutions for sensitive individuals

When selecting heating options, consider systems that do not add to indoor humidity. For example, unflued gas heaters release water vapor into the air, increasing humidity levels. Electric heaters or flued gas heaters are preferable choices as they provide warmth without adding moisture to the indoor environment.

Additionally, ensure that heating systems are well-maintained and that rooms are properly ventilated to prevent moisture build-up.
