Scientists at the University of Colorado Boulder have found that toothbrushes and shower heads contain bacteria that strengthen the oral cavity and the human immune system. This was reported by Science Daily.
Scientists analyzed the microbiome (community of microorganisms) on the surfaces of watering cans and toothbrushes in US homes. They found that the bacteria on these everyday items help the body resist various diseases and maintain a healthy balance of microflora on the skin.
In addition, scientists have found that toothbrushes live on beneficial microorganisms that help maintain oral health. These microorganisms produce substances that can prevent the development of caries and other dental diseases.
The study's findings highlight that over-sterilization of personal care products can be harmful to health. Moderate amounts of certain types of bacteria are important for normal functioning of the body and maintaining immunity.
Experts recommend avoiding the use of harsh antibacterial products on shower heads and toothbrushes. Instead, it is enough to wash them with warm water and change them as they wear out, so as not to disturb the natural balance of beneficial microflora.
