Hydrate Carefully

We've all heard the criticisms that bottled water is a needlessly wasteful product. Many consumers concerned with the health of themselves and the environment are drinking their water out of reusable containers. Unfortunately, there are dangers lurking there as well. Polycarbonate water bottles (like Nalgene) release small amounts of Bisphenol A (BPA), an estrogen-like chemical. Makers of water bottles have long-claimed that the levels were safe, but a growing number of scientists are beginning to have their doubts. Studies have shown BPA to have negative impacts in animal studies, and the human health concerns include increased cancer risks, reduced fertility and childhood behavioral problems. In a recent study, University of Cincinnati scientists tested both old and new polycarbonate water bottles exposed to boiling water. Their results showed BPA being released as 55 times the normal room temperature rate. BPA is not a rare chemical, either. Besides water bottles, it is found in many baby bottles, the epoxy resins lining most tin cans and dental fillings. Some retailers, such as Mountain Equipment Co-op of Canada, have actually chosen to pull their polycarbonate water bottles from their shelves until more conclusive research is done. Don't give up yet on your quest to remain hydrated. Companies are already coming up with alternatives, like CamelBak, which is now offering a new BPA-free water bottle. Drink responsibly!
