The Bedroom Chemistry Atlas

What's actually in your bed?

A plain-language guide to the 0 chemicals researchers have measured in mattresses, bedding and bedroom air — what each one is, where it comes from, and why it matters. Every entry is cited to the original research. No scare tactics. No affiliate links.

1 Filter by where you'll find it — or just search “sunscreen”, “smoke”, “BPA”. 2 Tap any card for a plain-English “where” & “why”. 3 Open the full entry for the cited science.

What the hazard tags mean

The little coloured tag on a card is a cancer-hazard rating from the World Health Organization's IARC. Important: it rates how strong the evidence is that something can cause cancer — not how risky your everyday exposure actually is. Most bedroom exposures are low. The full entry always gives the honest, in-context read.

1 Known to cause cancer 2A Probably causes cancer 2B Possibly causes cancer 3 Studied — not a proven carcinogen P65 On California's Prop 65 list

An evolving reference — new compounds are added as the research expands. Hazard ratings reflect IARC, EPA, ECHA, Stockholm Convention and California Prop 65 classifications. No single card is a verdict on your home — tap through for the cited, in-context detail.
