The article explains that after a funeral, it is common for families to recommend bathing upon returning home, a tradition that has deep scientific roots. Proper hygiene is emphasized, particularly in the context of the deceased, whose immune system ceases to function after death, leading to an increase in harmful bacteria like E. coli and Clostridium that can proliferate and cause potential health risks.

These bacteria can become airborne and come into contact with attendees at the funeral, leading to concerns about the transmission of infections. The act of bathing with soap is suggested as a vital practice to remove these bacteria and other harmful germs from the skin and clothing, thereby reducing the risk of spreading pathogens to family members who were not present at the funeral.

The article highlights that while many people might associate this practice with religious beliefs, the underlying scientific reasoning offers an important public health perspective that encourages hygiene after exposure to potentially infectious environments, a practice that remains relevant even in modern contexts with better understanding of diseases.
