Use soap and water!

Smithsonian Magazine gives five reasons why you should probably stop using antibacterial soaps.

1. Antibacterial soaps are no more effective than conventional soap and water. So far, analyses of the health benefits don't show any evidence that triclosan can reduce the transmission of respiratory or gastrointestinal infections. This might be due to the fact that antibacterial soaps specifically target bacteria, but not the viruses that cause the majority of seasonal colds and flus.

2. Antibacterial soaps have the potential to create antibiotic-resistant bacteria

3. Antibacterial soaps could act as endocrine disruptors. A number of studies have found that, in rats, frogs and other animals, triclosan appears to interfere with the body's regulation of thyroid hormone, perhaps because it chemically resembles the hormone closely enough that it can bind to its receptor sites. If this is the case in humans, too, there are worries that it could lead to problems such as infertility, artificially-advanced early puberty, obesity and cancer.

4. The antibacterial soaps might lead to other health problems, too. There's evidence that children with prolonged exposure to triclosan have a higher chance of developing allergies, including peanut allergies and hay fever. Scientists speculate that this could be a result of reduced exposure to bacteria, which could be necessary for proper immune system functioning and development.

Another study found evidence that triclosan interfered with muscle contractions in human cells, as well as muscle activity in live mice and minnows. This is especially concerning given other findings that the chemical can penetrate the skin and enter the bloodstream more easily than originally thought. A 2008 survey, for instance, found triclosan in the urine of 75 percent of people tested.

5. Antibacterial soaps are bad for the environment.
