Scientists have said that using the grandmother’s method of bathing provides you with healthy skin, as washing the body in the old traditional way, which relies on washing the folds of the body, maintains the health of the skin microbiome, according to the Daily Express website.
One study suggests that the best way to clean yourself during… Bathing Using the “grandmother’s method” or “grandmother’s hypothesis,” a team of researchers from the Institute for Computational Biology at George Washington University investigated the skin microbiome — the community of microorganisms that live on people’s skin — in healthy individuals, focusing on differences across areas of the skin. , for example between the arms, and often neglected washing areas such as the navel, abdomen and behind the ears.
Keith Crandall, director of the Institute for Computational Biology and professor of biostatistics and bioinformatics at George Washington University, said that his grandmother always asked him to “rub behind the ears, between the toes, and in the navel,” explaining that these areas may harbor different types of harmful bacteria found in areas where Other parts of the body, which are often neglected during washing.
As part of the study, samples were taken from the legs, forearms, behind the ears, between the toes and in the navel of 129 graduate students. The students were taught how to sequence the DNA in these skin samples, comparing discarded fatty areas to samples taken from dry, cleaner areas.
The results proved Kendall’s grandmother was right—regularly cleaned areas have a more diverse microbiome and contain a healthier population of microbes than neglected areas.
“Dry skin areas (forearms and shins) were more toned, richer, and functionally distinct than oily (behind the ears) and moist (belly button and between toes) areas,” the team wrote in their study. The skin microbiome is made up of microbes that can be beneficial or harmful to you. Dr. Crandall emphasized that if the balance shifts towards harmful microbes, this could lead to diseases such as eczema or acne. The relationship between microbiome health and human health still needs more research, but the study served as a reference point for a healthy microbiome in adults.
