Winter prompts households to seal up tightly as temperatures drop to conserve warmth, inadvertently compromising indoor air quality. As windows remain shut and heating systems run, issues emerge. Understanding these issues is crucial in mitigating health risks associated with indoor environments in colder climates.
1. Reduced Ventilation
During winter, homes tend to seal up tight to retain warmth, reducing the fresh airflow from outdoors. Closed windows and minimized ventilation systems trap indoor air, allowing pollutants to accumulate. With less air exchange, indoor air quality can deteriorate as pollutants like dust, pet dander, and volatile organic compounds (VOCs) linger longer, leading to respiratory issues and allergies.
2. Increased Indoor Pollutants
With people spending more time indoors due to colder weather, indoor activities contribute to higher levels of pollutants. Cooking, burning candles, using cleaning products, and even hobbies like painting or crafting release particles and gases into the air. Inadequate ventilation allows these pollutants to accumulate, exacerbating respiratory problems and affecting overall health.
3. High Humidity Levels
Cold outdoor air holds less moisture, and the relative humidity drops significantly when heated indoors. To combat this, people often use humidifiers. However, improper use or excess moisture can elevate indoor humidity levels. Excessive moisture can promote mold growth, exacerbate allergies, and cause respiratory problems. Furthermore, high humidity levels create a conducive environment for dust mites, another common indoor allergen.
4. Mold Growth
Mold thrives in damp and poorly ventilated areas. During winter, condensation can accumulate on windows and walls due to temperature differences between indoor and outdoor environments. When this moisture isn’t properly addressed, it provides a breeding ground for mold. Persistent dampness in basements, bathrooms, or attics can lead to mold growth, triggering allergic reactions, asthma, and other respiratory issues.
5. Chemical Exposure
Many households use various chemicals for cleaning, pest control, and maintenance. With reduced ventilation, these chemicals’ volatile compounds accumulate indoors. Prolonged exposure to these substances can lead to irritation of the eyes, nose, and throat. It can sometimes cause headaches, dizziness, or more severe health issues. Additionally, off-gassing from furniture, carpets, and building materials containing formaldehyde and other chemicals can worsen indoor air quality during winter.
