Is it safe to paint or renovate a nursery while pregnant?

What's actually in it

Wall paint, primers, wood stains, and new furniture all release volatile organic compounds (VOCs) into the air. Common culprits include formaldehyde, benzene, toluene, and xylene. These chemicals evaporate from wet paint and new materials for days or even weeks after application. The process is called off-gassing.

A freshly painted nursery with new furniture can have VOC levels many times higher than normal indoor air. That "new paint smell" is literally a cocktail of chemicals you're breathing in.

What the research says

A 2026 study in Environ Int found that prenatal exposure to indoor VOCs impaired synaptic plasticity and cognitive function in offspring. The researchers showed that VOC exposure during pregnancy disrupted retinol (vitamin A) metabolism in the developing brain, which is essential for forming healthy neural connections.

Synaptic plasticity is how the brain learns and forms memories. When it's impaired during fetal development, the effects can last a lifetime. The study provides a clear biological mechanism for how something as common as paint fumes can affect a baby's brain before birth.

The risks are highest during the first and second trimesters, when the brain is forming its basic architecture. But exposure at any point during pregnancy is worth avoiding.

If you need to paint the nursery, finish the job at least 2 to 4 weeks before your due date and have someone else do the painting. Choose zero-VOC or low-VOC paints. Keep windows open for ventilation. For new furniture, let it off-gas in a well-ventilated room or outdoors before moving it into the nursery.
