A study from the Autonomous University of Barcelona reveals that polymer-based tea bags release billions of nanoplastics and microplastics into hot water, potentially entering the bloodstream and intestinal cells. This exposure can be minimized by using loose-leaf tea, selecting natural material tea bags, and brewing with filtered water, preventing possible health risks.
