Do you use a plastic water bottle over and over and into the next day? Well, stop it. The main thing is the soft plastic water bottles showed that after 24 hours there are a TON of chemicals in it. Junk that can mess with your hormones and, I hate to be so dramatic, could potentially cause cancer. This research is from the University of Copenhagen.
And if you think that you'll run it through the dishwasher and use it again. REALLY STOP it. There were even more chemicals after the researchers did that test.
The researchers suggest a quality stainless steel bottle instead.
When it comes to your plastic water bottle be ONE AND DONE!
