What common practice should be followed after using the restroom?

Washing hands is an essential practice after using the restroom because it effectively removes pathogens, including bacteria and viruses, that may be present on the hands. This action helps prevent the transmission of infections, especially in environments like healthcare settings where the risk of spreading contaminants is high. Proper handwashing techniques, which include using soap and water for at least 20 seconds, significantly reduce the likelihood of cross-contamination and the spread of gastrointestinal and respiratory illnesses.

In contrast, changing uniforms may be unnecessary after every restroom visit, as uniforms are generally not a direct source of infection when proper hand hygiene is practiced. While the use of antiseptics can be beneficial in some situations, it is not a replacement for thorough handwashing, which is the most reliable method for maintaining hand hygiene. Similarly, using a disinfectant spray is relevant for cleaning surfaces rather than for personal hygiene practices post-restroom use.
