Drinking water from copper cups after storing it overnight has become a popular trend on social media.
Supporters claim that copper-infused water improves digestion, strengthens immunity, and promotes healthy aging. Although copper utensils have gained renewed attention, several cultures have used them for hundreds of years.
Experts Warn Against Exaggerated Claims
Experts say some claims about drinking water from copper cups contain a degree of truth. However, social media posts often exaggerate the potential benefits.
Copper’s antimicrobial properties remain its most strongly supported advantage.
Copper May Help Reduce Bacteria
Research suggests that storing water in a copper container for several hours may reduce certain harmful bacteria.
For this reason, communities with limited access to safe drinking water historically relied on copper vessels. However, this benefit becomes less significant when people already have access to clean and properly treated water.
Meanwhile, strong evidence does not support claims that copper water improves digestion, reduces inflammation, enhances thyroid function, or significantly boosts overall health.
Copper Is an Essential Mineral
The body needs copper to support several important functions. Nevertheless, most people already receive enough copper through a balanced diet.
Copper cups also offer an alternative to plastic containers that may contain certain chemicals.
However, frequent or improper use of copper utensils may gradually increase copper intake. Excessive exposure can lead to digestive problems, including nausea, vomiting, and stomach pain.
Therefore, people with conditions that affect copper metabolism should consult a doctor before regularly drinking water stored in copper containers.
