The amount of dangerous bisphenol A (BPA) that leaches from plastic bottles into the drinks they contain is most dependent on the liquid‘s temperature, according to new research. When both new and used polycarbonate drinking bottles were exposed to boiling hot water, BPA was released 55 times more rapidly.
BPA an endocrine disruptor which mimics your body‘s natural hormones. Hormones serve different functions throughout your body. BPA has been shown to affect reproduction and brain development.
The increased release of BPA continued even after the hot liquid was removed, meaning that even washing plastic cups or bottles in a hot dishwasher could lead to increased BPA content in cold drinks.
