Most of us don’t give a second thought to common household items we use every day. But recent findings suggest that some of these seemingly harmless things might carry health risks if not used or cleaned properly. While the danger isn’t always immediate or severe, being aware can help you make smarter choices for your family’s well-being. Here’s what you need to know.
1. Scented Candles and Air Fresheners
Scented candles and plug-in air fresheners make our homes smell lovely, but some of them can release substances called volatile organic compounds (VOCs), such as formaldehyde or benzene, especially when burned or heated. At high levels or with long-term exposure in unventilated spaces, these compounds may irritate the respiratory system or contribute to other health issues. The good news is, occasional use in a well-ventilated room is generally safe. For safer alternatives, try essential oil diffusers or beeswax candles.
2. Humidifiers
Humidifiers can make your home more comfortable in dry weather, but if not cleaned regularly, they may spread bacteria and mold spores into the air. Dirty humidifiers have been linked to respiratory issues, especially for people with asthma or allergies. In rare cases, poorly maintained humidifiers have led to serious conditions like humidifier lung. Be sure to clean and dry your humidifier daily, and use distilled water to avoid mineral buildup.
3. Dry Cleaning Chemicals
Some dry cleaners use a chemical called perchloroethylene (PERC), which is classified as a possible human carcinogen by health authorities. While brief exposure from your clothes is low risk, it’s a good habit to remove the plastic cover and air your dry-cleaned garments outside for a few hours. If possible, look for cleaners that advertise as “eco-friendly” or “green” and avoid PERC altogether.
4. Thermal Paper Receipts
Cash register receipts often use thermal paper that contains Bisphenol A (BPA), a chemical linked to hormone disruption. While the amount absorbed through skin is low, repeated handling can increase exposure. If you work in retail or frequently receive printed receipts, consider minimizing contact or choosing digital receipts when possible. Many businesses are switching to BPA-free paper, but alternatives may still contain similar chemicals.
5. Hairbrushes
A dirty hairbrush can accumulate oils, dead skin, hair product residue, and even bacteria. Regularly using an unclean brush may contribute to scalp issues like dandruff or clogged follicles. Experts recommend removing hair after each use and washing your brush weekly with warm water and gentle shampoo to keep it clean and effective.
6. Remote Controls
TV remotes, especially in shared spaces or hotels, are often overlooked when it comes to cleaning. Studies have shown they can harbor bacteria such as E. coli and Staphylococcus if not disinfected. Cleaning your remotes regularly with disinfecting wipes is a quick and easy way to reduce germ exposure—especially during cold and flu season.
Final Thoughts
There’s no need to panic over the everyday items in your home. Most of the risks discussed here are low and manageable with basic hygiene and awareness. Making small changes—like airing out clothes, cleaning your humidifier, or choosing natural air fresheners—can help you maintain a healthier living environment for you and your loved ones.
