<pclass="answer">Next, with the cooperation of 32 nursing students, the number of bacteria on hands and hands and fingers after defecation was investigated depending on whether or not the bidet function was used.<br> The results showed that the average value was 40,000 bacteria/hands and fingers when unused, and 4,200 bacteria/hands and fingers when used (Table 1). <br>Using the bidet function reduced the number of bacteria contaminating hands to approximately 1/10. The duration and water pressure (high, medium, or low) for washing the buttocks were left up to each individual in this study.</p>
