The Surprising Health Benefits of Wood

When we think about wood in our homes, we often focus on its aesthetics, warmth, and organic appeal. However, wood offers another remarkable benefit—its naturally hygienic properties. Here are five scientifically backed ways wood can contribute to a cleaner and healthier living space!

1. Wooden Cutting Boards Are More Hygienic Than Plastic

First things first, there’s been a long-standing misconception that plastic cutting boards are more sanitary than wooden ones. However, research from the University of Wisconsin's Food Research Institute found that bacteria like E. coli and Salmonella survive longer on plastic surfaces than on wood. Wood’s porous structure absorbs bacteria, trapping and effectively desiccating them, preventing further growth. In contrast, plastic cutting boards develop knife grooves that harbor bacteria, making them harder to sanitize effectively. Additionally, each cut on a plastic board creates microplastics, which we all know we already have enough of!

2. Wood Naturally Inhibits Bacterial Growth

A study conducted by Dean O. Cliver, a microbiologist formerly at the University of Wisconsin’s Food Research Institute, found that certain wood species, such as oak and pine, contain antimicrobial compounds like tannins and terpenoids that help kill bacteria. Although these antimicrobial properties are more effective in "naked" wood, this natural self-sanitizing property is an important benefit when choosing kitchen surfaces and high-touch furniture.

3. Wood Enhances Health & Productivity in Living and Workspaces

Dr. Graham Lowe, a leading expert in workplace health, highlights the benefits of wood in green buildings. Wood’s biophilic properties—our innate connection to natural materials—help reduce stress, lower blood pressure, and improve focus, mood, and overall well-being. Green-certified wood buildings also enhance indoor air quality, reduce volatile organic compound (VOC) emissions, and improve acoustics, leading to better cognitive function, job satisfaction, and performance. Organizations that incorporate wood into their spaces benefit from reduced absenteeism, higher employee retention, and a stronger eco-conscious brand image.

4. Wood Regulates Humidity, Reducing Mold and Mildew Growth

Unlike plastic, wood is hygroscopic, meaning it absorbs and releases moisture based on the environment. By naturally regulating humidity, wooden furniture, and decor help prevent excessive moisture buildup, which can lead to mold and mildew growth. Research from the Forest Products Journal found that wooden surfaces in homes maintain a more stable humidity level, reducing conditions favorable to fungal proliferation.

5. A Sustainable, Toxin-Free Alternative to synthetic Antimicrobial Coatings

Many commercial antimicrobial coatings on plastic and metal surfaces contain harmful synthetic coatings, which have raised concerns about potential health risks and environmental impact. for example, several studies have shown that long-term exposure to triclosan could pose health risks. Although banned in the US in 2013, this chemical still exists in old items found in our homes. Side effects could range from allergies to bacterial resistance. Wood offers a natural alternative, providing antimicrobial benefits without added chemicals, highlighting the risks of antimicrobial resistance linked to synthetic coatings, and reinforcing the benefits of using naturally antibacterial materials.

Conclusion: Wood for a Cleaner Home

Wood isn’t just a beautiful, organic material—it’s also a smart choice for a cleaner, healthier home. Whether in cutting boards, furniture, or decor, wood’s natural antimicrobial properties contribute to a healthier living environment. Next time you’re choosing between wood, plastic, metal, or even composite wood, remember that wood offers more benefits beyond aesthetics!
