The jury is still out regarding whether antibacterial gels and hand sanitizers work, or if the chemicals used in them are bad for you. But the reality is that there’s no need to use chemical sanitizers when there are all-natural alternatives that can not only help you stay healthy, but smell good, too. When shopping at your health-food store, take a look at small vials of essential oils. Oils like tea tree, peppermint and rosemary have natural antibacterial properties that disinfect on contact. Carry a small bottle, put a few drops in the palm of your hands and rub away. These oils disinfect and leave a really pleasant scent.
