There are certain points in the year when it seems just about impossible to avoid catching a cold. This is usually because every man, woman and child around has a bug, and is coughing and sneezing their way around town. This is especially true in the winter. However, there are certain ways in which people can help to stave off cold and flu symptoms, as long as they are diligent and make sure to keep their immune system up.

One way to avoid getting sick even when everyone else is sick is for people to wash their hands after coming into contact with others. It may sound a little extreme, but carrying a hand sanitizer will go a long way. By the same token, people should avoid touching their eyes and nose too much, but especially right after they have come into contact with someone else.

The health of people during the cold and flu season can also be boosted by getting enough sleep. This sounds like a simple idea, but it is one that so few people take to heart. Getting a full eight to 10 hours of sleep is one of the best ways to ensure that one's body is fighting the viruses at full capacity.

There are many healthy foods that can also contribute to one's remaining healthy. Jeff Robertson, who is an MD and health insurer at Regence, says, 'Eating plenty of fruits and vegetables supports your immune system.' Fruits with vitamin C, such as citrus fruits, should be given particular priority.

For those who are smokers, a final tip to avoid getting sick is to quit. In 2004, the Archives of Internal Medicine published a study that showed the structural changes caused in the respiratory tract by smoking increases the risk of infections. Thus, when it comes to cold and flu season, the motivation to quit is stronger than ever.

On the topic of keeping the lungs healthy, staying active and working out will help to keep the immune system healthy. Dr and Just Wellness founder Ann G. Kulze emphasises “Get those sweats on and exercise.” Depending on the person, this exercise could be anything from a game of football to a walk up the stairs. The point is to keep the body active in some way.

Finally, in an interesting development, Carl Charnetski, who is a psychology professor at Wilkes University, recently conducted a study that found a positive attitude to be a beneficial factor in combating illness. This is simply thanks to the fact that happiness boosts the immune system. The activities that induce the most happiness will vary from person to person, but the activities that were highlighted in the study included spending quality time with a favourite pet, and having intimate time with a partner.
