Some of the tips which can help you to prevent from common cold are as follows-
* Wash your hands often. This is probably the single best measure to prevent transmission of colds. Especially after shopping, going to the gym, or spending time in public places, hand washing is critical. Frequent hand washing can destroy viruses that you have acquired from touching surfaces used by other people. You can also carry a small tube of hand sanitizer or sanitizing hand wipes when visiting public places. Teach your children the importance of hand washing too.
* Avoid touching your face, especially the nose, mouth, and eye areas, if you are around someone with a cold or have been touching surfaces in a public area.
* Don't smoke. Cigarette smoke can irritate the airways and increase susceptibility to colds and other infections.
* Maintain a healthy lifestyle. While there isn't direct evidence to show that eating well or exercising can prevent colds, maintenance of a healthy lifestyle, with adequate sleep, good nutrition and physical exercise can help ensure that your immune system is in good condition and ready to fight infection if it occurs.
