Unfortunately, yes. A bed can make you sick for a few reasons. One, a mattress with cheap materials (synthetic latex, poorly-made memory foam, and poly-foam) can sometimes contain chemicals like formaldehyde and benzene, which have been linked to cancer, developmental brain disorders, and more. Two, old mattresses can accumulate dust and other allergens over time. If you don’t wash or vacuum your mattress periodically, you’ll inhale and ingest allergens, dirt, and dust throughout the night, leading to a number of different health issues.
