Regular moderate exercise such as walking may prevent the common cold a study reports in the American Journal Of Medicine. The exercise/colds study took 115 overweight seattle women, average age 61, and split them into two groups, the exercise group, and the control stretching program group. Overall the non-exercise group came down with twice the number of colds as the continuous exercise (walking) group.

Researchers are not clear as to exactly why regular exercise helps prevent colds, but some feel physical activity aids immune function.

In my opinion, more reasearch needs to be done in the field. I would like to see the sample group grow to thousands. Until then, lace your walking shows and go take your daily walk. You health depends upon it!
