Copper Water Bottles: A Modern Gimmick Which Can Make You Seriously Sick
The concept of drinking water from copper vessels was acquired from our ancestors. They used various sizes of copper vessels to store and to drink water from it. Due to many health benefits of copper, now-a-days every manufacturers are making new products made with copper including water bottles. But is it really safe to drink water from these bottles?
If you look at the age old copper vessels, they were designed in such a way that the vessels had no complicated bends and designs. The opening of the vessels was large. The reason was a familiar chemical reaction. Copper slowly reacts with atmospheric oxygen to form a layer of brown-black copper oxide which protects the underlying metal from further corrosion. This copper oxide has slow but sure bad effects on our body. It can cause gastrointestinal irritation with symptoms such as nausea, vomiting, and diarrhea.
To get rid off copper oxide, vessels have to be washed thoroughly with hands. They designed opening of the vessels in such a way that hands can reach each and every corner to clean it properly. People those days used either lemon or tamarind mixed with ash to wash copper vessels. They did not use any detergent or other chemicals for cleaning. Because copper can easily react with those and create other harmful salts.
Complicated designs, narrow bends, small mouths are out of reach from hands while washing it. When these areas are left unattended, corrosion happens. A copper water bottle can not be scrubbed properly due to small opening. Every copper water bottle after a day or two has the same harmful copper oxide inside it.
Without daily and proper cleaning all copper utensils are bad for health. So better not to use copper water bottles at all. You can always go for a stainless steel or a glass bottle. Copper water bottles are just another gimmick from modern manufacturers who are simply hiding few simple facts.
