I was reading sometime back that our gut has good bacteria and initially when people didn't understand them there was a phase when some people were using antibiotics to kill their gut bacteria. Today, Most people agree on the benefits of good bacteria in our gut. Around 2010 I was reading an article about other good bacteria which also resides on our skin and then I decided to stop using anti-bacterial. I make sure that I was my hands thoroughly with water and use soap if required.
