If you have been wiping your butt with a tissue paper, then you have been doing it all wrong. Wet wipes are better, doctor told the Independent. "Tissue paper leaves faeces behind and could also be rough on your bottom causing irritations and anal fissures," said Dr. Rose George.
A caregiving blog Hosiped went on to demonstrate how bad tissue papers are in wiping your anus. If you pour some chocolate on a table and then try to wipe it off with a tissue paper, it will not wipe it really clean. All that happens is that the waste is pushed to the crevices and get spread to other parts of the table. This is what the tissue paper does; it spreads faeces on your butt rather than cleaning it. This could lead to urinary tract infections.
Wet wipes, on the other hand, pick out all the dirt because they are moist. This could be the reason why Japanese, Italians and Greeks use water powered bidets to wash off their dirt after emptying their bowels.
