To help protect yourself from catching the common cold or flu, it is important to practice good hygiene and keep your hands clean. Make sure you wash them regularly with soap and water for at least 20 seconds, especially after being in public places like grocery stores and work. Additionally, avoid touching your face often, cover your mouth and nose when coughing and sneezing, and try to get plenty of rest and exercise.
