The winter season can be a hard time for many because it usually means the beginning of the flu season. For many with a less than ideal immune system this can mean agony. Many people seem to get one cold right after another during the winter months and rather than get better they usually get worse. Many people actually have a lot of misconceptions about what causes the common cold. Many people believe that the actual colder temperatures have something to do this but the reality is that no study ever done has been able to show a correlation between temperature and the ability of the virus to reproduce. A better and more reliable theory is that the cold causes people to spend more time indoors where they are in closer proximity to each other and then sharing more germs.
Washing your hands is the number one thing that you can do to prevent colds. Through the day you touch a myriad of objects and your both leave and pick up microbes on your hands. All it takes is touching your mouth or eyes to transfer the virus internally and become ill.
Another very effective preventive treatment is to take a multivitamin every day. This is not intended to be a cure-all but will help to pick up on nutrition where your normal diet may have left off. There are a lot of multivitamins on the market and when it comes to choosing one just remember that the simpler the better.
