During the past few years many neew studies have come out explaining the risks of using nalgene bottles.
Nalgene bottles are great for hiking, trips, school, and many other great activities, but in recent years new studies have confirmed that Nalgene bottles actually cause cancer. When put under harsh conditions such as putting boiling water and freezing water within the bottles small particles of plastic neoprene fall off into the water being drunk. These may only be small particles of plastic but they can be ever so damaging to your daily health.
In the daily life of many people you are used to putting your water bottle into the freezer at night to freeze the water. The particles find there way into your blood stream and are able to further attach themselves to other cells inside your body. Once attached these particles unseen to the eye mutate the cells growth making abnormal cists which in turn will turn into cancerous tumors.
The short term effects may not be staggering but the long term affects of such a dangerous intake can cause life ending circumstances.
