While we haven't quite figured out how to cure a common cold (would someone get on that, please?), we can offer ways to address cold and flu viruses when they happen. First of all, rely on our collection of tips for preventing illness (like monitoring and purifying the air quality in your home, eating an immune-boosting diet, stress relief, and getting enough sleep). Then, trust us to stay on top of the latest innovations in remedying colds, flu, and allergies (like neti pots and antiviral medications).
