A recent study published in Environmental Science and Technology has highlighted the potential negative impacts of overusing disinfectants on our health and the environment. Many cleaning products, including antibacterial soaps, contain substances called quaternary ammonium compounds (QACs), which are effective at destroying germs, fungi, and viruses.
However, the study suggests that excessive use of these products may be harmful. Consuming too much of the active ingredient can be irritating to the skin and may have adverse effects on our health. Additionally, overcleaning can potentially lead to the development of bacterial resistance, where bacteria become resistant to the disinfectant, making it less effective in the long run.
Dr. Mark Olszyk with Carroll Hospital warns that by overusing disinfectants, we may inadvertently breed bacteria with built-in resistance, creating a highly resistant species of bacteria. This outcome is the opposite of what we intend when using disinfectants to eliminate bacteria.
It’s important to strike a balance in cleaning practices and follow the recommended guidelines for disinfectant use. Regular handwashing with soap and water, along with targeted disinfection in high-touch areas, is generally sufficient to maintain hygiene and reduce the risk of infection without resorting to excessive use of disinfectants.
