Chemicals commonly found in plastic products may interfere with the body’s natural 24-hour sleep-wake cycle in a manner similar to the stimulant effect of caffeine, reports the Baltimore Chronicle, citing Environmental International.
The study focused on substances released from feeding tubes made of polyvinyl chloride (PVC) and hydration bags composed of polyurethane—materials frequently used in food packaging, medical devices, toys, and furniture. Scientists discovered that these compounds can alter cellular signaling involved in regulating the body’s internal clock, causing a shift of up to 17 minutes in circadian rhythms.
The circadian clock governs the timing of numerous physiological processes, including sleep patterns, hormone release, and metabolism. Disruptions to this clock have been linked to increased risks of obesity, cardiovascular disease, and neurodegenerative conditions like dementia.
Martin Wagner, a co-author of the study from the Norwegian University of Science and Technology, emphasized the critical role of circadian rhythms in maintaining overall health. He highlighted the need for further research to understand the full impact of plastic-associated chemicals on the body’s internal timekeeping mechanisms.
Researchers pointed out that these findings add to growing concerns over the biological effects of everyday plastic exposure. The authors call for a systemic overhaul in the design and production of plastic materials to ensure they are safe for human use.
