Are chemicals in new mattresses linked to headaches and allergies?

What's actually in it

Many conventional mattresses contain brominated flame retardants. These chemicals are added to foam to slow down fire spread. They don't stay trapped in the mattress forever. Instead, they can shed into the air you breathe while you sleep.

These chemicals are part of a larger group of substances that researchers track for their impact on human health. While manufacturers often prioritize fire safety, the chemical trade-off can affect your immune system.

What the research says

A 2026 study in Sci Total Environ found a clear association between brominated flame retardants and the diagnosis or symptoms of allergies in a nationally representative sample of people in the US.

This is not the only concern regarding chemicals in our living spaces. Other research highlights how common household chemicals can build up in our bodies. For example, a 2026 study in Int J Hyg Environ Health examined the risks of nine different reproductive toxic chemicals, showing that exposure to mixtures of these substances is a significant issue for children and adolescents.

Additionally, a 2026 study in Environ Sci Technol looked at how 1,4-dioxane exposure integrates into our biological systems, further proving that the chemicals in our home environment are not just sitting there. They are interacting with our bodies in ways that science is only beginning to fully map out.
