Handwashing is More Effective Than Taking Vitamins for Cold Prevention

"Not only is there no proof that some antioxidants prolong life, but there is some evidence that certain products may even lead to earlier death", says professor Peter Sawicki, the Institute's director.

"Positive" news gives people hope, which can quickly spread, become deeply held beliefs. Sawicki notes, "It can be very difficult to accept that these beliefs are myths, but they are not true if further research does not confirm them or the research points to the opposite conclusion."

Whether it is caused by a mild cold or the flu, a runny nose and sore throat are signs of a viral infection. Many people are absolutely convinced that vitamin C provides protection against respiratory infections. Yet research has shown that vitamin C does not prevent infection, and that high doses can even be harmful.

There are many simple but effective ways to lower the risk of respiratory infections. These include frequently washing your hands with normal soap and water, and not touching your face with your hands. People who already have a respiratory infection can stop it from spreading by throwing away tissues immediately after using them and not shaking hands with other people.
