Copper is a metal that has been used for centuries for its antimicrobial properties. It has been shown to have antibacterial, antifungal, and antiviral properties, making it an effective tool in the fight against infections.

One study, published in 2011, found that copper surfaces were effective in reducing the bacterial load in hospital environments. The study compared the bacterial load on copper surfaces to that on stainless steel and plastic surfaces in a hospital setting and found that copper surfaces had significantly lower bacterial counts.

Another study, published in 2014, found that copper alloys were effective in reducing the incidence of secondary infections in intensive care units (ICUs). The study compared the incidence of secondary infections on copper alloy surfaces to that on stainless steel and plastic surfaces in ICUs and found that copper alloy surfaces had a significantly lower incidence of secondary infections.

In addition to its antibacterial properties, copper has also been shown to have antifungal and antiviral properties. A study published in 2015 found that copper was effective in inhibiting the growth of several different types of fungi. (3) Another study, published in 2016, found that copper was effective in inactivating several different types of viruses, including norovirus and influenza virus. (4)

Copper sleep surfaces, such as copper-infused mattresses and pillows, may be an effective way to create a more sterile bedroom environment. Copper has been shown to reduce overall bacterial loads in the immediate environment, which may help to alleviate acne and other skin conditions caused by bacteria.

While the evidence for the use of copper for its antimicrobial properties is strong, it is important to note that the use of copper is not without risk. Copper can be toxic if ingested in large amounts, and it is important to follow proper safety guidelines when handling copper.

In conclusion, copper has strong antibacterial, antifungal, and antiviral properties. It has been shown to be effective in reducing the bacterial load in hospital environments and in reducing the incidence of secondary infections in ICUs. Copper has also been shown to be effective in inhibiting the growth of fungi and in inactivating viruses. Copper sleep surfaces may be a useful way to create a more sterile bedroom environment and may help to alleviate acne and other skin conditions caused by bacteria. However, it is important to follow proper safety guidelines when handling copper.
