While we all like to think that our bad health habits aren't that harmful, the truth is some behaviors are so unhealthy they're toxic. Smoking, excessive drinking and lack of exercise are all things we know that are dangerous, but there's so many more things that we don't think about that can cause serious damage. Eat This, Not That! Health spoke with Gabby Martin, a supervisor at Bio Recovery who revealed what habits we do at home that are toxic and ranked them in order of their toxicity.  Read on—and to ensure your health and the health of others, don't miss these.

The number one thing people can do that's really toxic is reuse an old dirty sponge. Martin asks, "Did you know that microbiologists have found a sponge harbors more harmful bacteria than any other object in your home? Technically, it should be replaced once a week. Most people forget about their sponge until it gets to a serious state of disrepair (or just plain nasty). It's also very overlooked how bad sponges get, particularly because they absorb so much."
