Can I burn candles while pregnant? Here's the truth.

April 25, 2026

What every expecting mother needs to know about candles, chemicals, and how to stay safe.

You're pregnant, you love the cosy glow of a candle, and now you're not sure if it's safe. It's a question thousands of expectant mothers search every single day — and the answer is more nuanced than most candle brands want you to know. The short answer: it depends entirely on what's in the candle. Some candles are genuinely unsafe during pregnancy. Others are completely fine. And knowing the difference could matter more than you think. Let's go through everything you need to know — no fluff, no fear-mongering, just the facts.

Why pregnancy makes you more vulnerable to candle chemicals

When you're pregnant, your body is working in overdrive. Your blood volume increases, your respiratory rate rises, and your immune system shifts to protect the growing life inside you. All of this means you're absorbing more of what's in the air around you — and so is your baby. Chemicals you breathe in can cross the placental barrier and reach your developing baby directly. This is especially significant during the first trimester, when your baby's organs are forming. The risks aren't always dramatic or immediate — but they're real, and they're worth taking seriously.

The problem with most candles

Here's something most candle brands don't advertise: the majority of mainstream candles — including many labelled 'natural' — are made from paraffin wax, a byproduct of crude oil refining. When paraffin burns, it releases volatile organic compounds (VOCs) including benzene and toluene — chemicals registered as toxins by the US Environmental Protection Agency and the CDC. But the wax is only part of the problem. The bigger concern for pregnant women is what's in the fragrance.

Synthetic fragrances and phthalates: what they are and why they matter

Most scented candles use synthetic fragrance oils, which frequently contain phthalates — a class of chemical compounds used to make fragrances last longer. Phthalates are known endocrine disruptors, meaning they interfere with the body's hormonal system. During pregnancy, your hormonal system is working harder than ever to support fetal development. Research has linked phthalate exposure to: • Hormone disruption in the developing fetus • Impaired immune system development • Increased risk of premature birth and low birth weight • Potential contributions to asthma and allergies in children When a synthetic candle burns, those phthalates become airborne — inhaled directly into your lungs and potentially absorbed through your skin. And because they're often not listed on labels (hiding under the umbrella term 'fragrance'), most people have no idea they're there.

'But my candle says it's natural...' This is where it gets frustrating.

The word 'natural' on a candle label is almost entirely unregulated. A candle can legally be called 'natural', 'eco', or even 'beeswax' while still containing paraffin blends, synthetic fragrance chemicals, and unlisted additives. Specifically: a candle can call itself a 'beeswax candle' if it contains any percentage of beeswax at all — including just 10% beeswax blended with 90% paraffin. The label wouldn't technically be a lie. This is why reading ingredient labels carefully — and choosing brands that list every ingredient openly — matters so much, especially during pregnancy.

So what candles ARE safe during pregnancy?

Not all candles are a risk. The safest candles during pregnancy share these characteristics:

• 100% pure beeswax or coconut wax — not blends

• Scented only with pure essential oils — not synthetic fragrance oils

• Natural cotton or wooden wicks — no metal core

• Full ingredient transparency — every ingredient listed

• No artificial dyes, additives, or preservatives

Beeswax in particular is worth highlighting. Unlike paraffin, pure beeswax produces minimal soot and releases negative ions when burned — ions that may help neutralise airborne particles like dust and pollen. A genuine 100% pure beeswax candle is the closest thing to an air-friendly candle that exists.

A note on essential oils during pregnancy

Even with essential-oil-scented candles, a little caution is wise. Some essential oils are best avoided during pregnancy — particularly in the first trimester. Generally safe options include lavender, chamomile, ylang ylang, and citrus oils. Oils to approach with more caution include rosemary, clary sage, and peppermint in large amounts. If you're unsure, always consult your midwife or obstetrician — especially in the first trimester. And always ensure your space is well-ventilated when burning any candle.

Practical tips for burning candles safely during pregnancy

• Always ventilate the room — open a window or door while a candle burns

• Never burn a candle in an enclosed space with no airflow

• Keep burn sessions to 1–2 hours maximum

• Never burn a candle while sleeping • Keep candles away from your face and direct breathing zone

How Lumiere Roots is different

At Lumiere Roots, we make candles with 100% pure farm-sourced beeswax and pure essential oils. That's it. No synthetic fragrances. No paraffin blends. No hidden additives. No fine print. We list every ingredient openly on every product — because we believe you have a right to know exactly what you're breathing in your home, especially when you're pregnant. Our pillar candles burn for 50 hours, and because our wax is so pure, the leftover wax once the candle is done is safe enough for your children to mould and play with. That's not a marketing claim — it's simply the result of using ingredients with nothing harmful in them. We built Lumiere Roots for families who refuse to compromise. Because you shouldn't have to choose between a cosy, beautiful home and a safe one.
