On average, we spend about 90% of our lives indoors, which makes indoor air quality an important aspect of our wellbeing. Research from the US EPA shows that indoor air can be 5-10x more polluted than outdoor air, and in some cases, up to 100x times worse.
This is especially relevant in the winter months, when we tend to keep our windows closed and spend even more time indoors. With less fresh air circulating, airborne pollutants can build up more quickly.
Poor indoor air quality can contribute to fatigue, headaches, asthma, allergies, mood changes, respiratory irritation, and long-term health concerns.
Why is indoor air so polluted?
Couple of reasons:
1. We don’t open our windows and modern homes are tightly sealed for energy efficiency, which limits fresh air exchange.
2. Many household items release chemicals into the air, including furniture, carpeting, paint, cleaning products, and fragranced items.
What can we do about it?
• Open windows daily, even briefly, to bring in fresh air when conditions allow
• Reduce unnecessary sources of indoor pollution. Start with fragranced items such as candles, plug-ins, and room sprays. Replace conventional cleaning and laundry products with lower-toxicity alternatives (the Environmental Working Group’s Guide to Healthy Cleaning free database is great place to start to find lower-tox options)
• Minimize fragranced personal care products when possible (EWG Skin Deep database is great resource/guide)
BONUS ✨ Consider adding an air filter to frequently used spaces. Look for two key features: HEPA filtration, which captures fine particles like dust, pollen, and smoke; and activated carbon, which captures gases, odors and VOCs. Both together offer the most comprehensive support.
The winter season is an ideal time to reassess what’s in your indoor environment and make a few small, intentional changes. Even simple, no-cost/low-cost shifts can make a meaningful difference in the air you breathe at home.
