Candles: Cozy Glow or Hidden Toxins?

As the days grow shorter and sunlight fades a little earlier each evening, many of us instinctively reach for candles—to bring warmth, peace, and a little sparkle into our homes. Their gentle flicker soothes the soul, and let’s be honest, everyone looks good in candlelight. It softens edges, evokes nostalgia, and makes a room feel just a little more magical. It’s no wonder they’re such a go-to gift during the holiday season.

But here’s the thing—while candles create ambiance, they may also be silently contributing to indoor air pollution. Yep, that cozy glow could come with an invisible cost to your health.

And trust me, I get it. Sometimes I wish I could just let it go and say, “Go ahead, light that cinnamon-sugar candle and don’t think twice.” But I can’t. I’ve seen too much and learned too much—and I feel compelled to keep sharing what I know. Because we deserve better than being exposed to toxins in the name of comfort.

So What’s the Problem with Conventional Candles?

Let’s start with the basics: there are no regulations requiring candle manufacturers to disclose what’s in their products. That means your favorite candle might contain anything—from petroleum byproducts and artificial dyes to synthetic fragrances and even toxic waste.

Most mass-produced candles are made from paraffin wax, a leftover sludge from the petroleum refining process. When burned, paraffin releases harmful chemicals—some of which are known carcinogens—into the air. The black soot you see? It’s similar to what comes out of a diesel engine. Not exactly the vibe we’re going for when we’re trying to relax at home.

Some candles may even contain lead-core wicks, especially if they’re imported or cheaply made. Burning these releases airborne lead, a serious health hazard—especially for children, pets, the elderly, or anyone with respiratory concerns.

Then there's fragrance. While it smells lovely, synthetic scents often include a cocktail of chemicals such as benzene, toluene, formaldehyde, and other volatile organic compounds (VOCs) that can trigger allergies, disrupt hormones, or worse.

And yes, all of this has been backed by studies—including ones from the EPA and independent researchers—confirming that burning many store-bought candles can contribute to indoor air pollution with lasting health effects.

Here’s What to Watch Out For:

Avoid these candle types whenever possible:

• Super cheap or dollar-store candles

• Imported candles without clear labeling

• Candles with metal-core wicks

• “Aromatherapy” candles from big brands like Glade or Febreze (the scents are synthetic and not actually therapeutic)

• Gel candles or those with an unnaturally bright color or strong artificial scent

Better, Safer Alternatives (That Still Smell Amazing)

Here’s the good news: you don’t have to give up on beautiful candles! There are clean-burning, non-toxic options that give you all the ambiance—without the health risks.

Look for candles made with:

• 100% Beeswax – Natural, non-toxic, and lightly scented with honey. Burns clean and lasts long.

• Soy Wax or Coconut Wax – Plant-based, biodegradable, and free from petrochemicals.

• Tallow or Lard – Traditional, sustainable options that can be locally sourced.

• Pure Essential Oils – Instead of synthetic fragrances, these provide natural, gentle aromas.

• Cotton or Wood Wicks – No metals, no toxins—just a clean, safe burn.

Beeswax candles are my personal favorite. Not only do they smell heavenly on their own, but they also naturally purify the air by releasing negative ions. How cool is that?

While these natural candles might cost a bit more upfront, they’re an investment in your health, your home, and your peace of mind. And when you make or buy them from trusted small-scale producers, you're also supporting more sustainable practices.

So, What’s the Takeaway?

You don’t have to ditch candlelight—you just have to be choosy. Creating a cozy, healthy home doesn’t mean giving up the little pleasures that make life sweet. It just means being informed, empowered, and a little more intentional.

And hey, if you want to learn how to make your own non-toxic candles (or swap recipes!), I’m always happy to help.

Light up your life—the safe way. ✨
