Chemicals in everyday plastics may disrupt the body’s natural 24-hour sleep-wake cycle and circadian rhythm in a way similar to coffee, which increases the risk of sleep disorders, diabetes, immune problems and cancer, new in vitro research shows.

The study looked at chemicals extracted from a PVC medical feeding tube and a polyurethane hydration pouch, like those used by long-distance runners. PVC and polyurethanes are also used in everything from kids toys to food packaging to furniture.

The findings showed for the first time how plastic chemicals probably wreak havoc on cell signals that regulate the body’s internal clock, throwing it off by up to 17 minutes.
