Plastics in everyday objects believed to disrupt sleep in same way as caffeine, study finds

Chemicals found in everyday plastics may disrupt the body’s natural sleep-wake cycle similarly to caffeine, The Guardian reported citing new research. The study, published in Environmental International, revealed that plastic chemicals from common materials like PVC medical tubes and polyurethane hydration pouches interfere with the body’s internal clock by up to 17 minutes. This disruption occurs through the activation of the adenosine receptor, a key regulator of circadian rhythm, which controls alertness and tiredness.

Unlike caffeine, which deactivates this receptor to keep us awake, plastic chemicals activate it but still cause similar delays in the body’s physiological processes. Although less potent than caffeine, the chemicals’ effects on cellular processes happen faster than their known hormone-related impacts. The study was conducted in vitro on human cells, with further research planned on animal models to better understand the consequences.

Experts warn this disruption could increase risks of sleep disorders, diabetes, immune problems, and cancer. They call for urgent changes in plastic design and production to ensure safety.
