Is it good to drink water from a copper cup over a long period?

Drinking water from copper cups over a long period is not advisable, as it may lead to excessive heavy metal intake, causing symptoms such as vomiting and abdominal pain. The detailed analysis is as follows:

With prolonged use, copper cups develop a surface layer of copper oxide, which is harmful to the human body. Additionally, when hot water comes into contact with the cup, copper ions can be released, posing potential health risks. While copper deficiency can cause various diseases, excessive intake may result in poisoning symptoms such as nausea and vomiting.

Copper is a trace element in the human body and should not be consumed in excess. Long-term use of copper cups may lead to heavy metal accumulation, resulting in symptoms of toxicity, including severe vomiting, nausea, diarrhea, abdominal pain, hematuria (blood in urine), and hematemesis (vomiting blood). Chronic use of copper cups for drinking water may also contribute to jaundice, pancreatitis, red blood cell toxicity, esophageal problems, and anemia.

In daily life, unless someone has a diagnosed copper deficiency, it's best to use glass or ceramic cups for drinking water, as these materials are generally safe and unlikely to cause harm to the body.
