This study published in the November issue of the American Journal of Medicine// reports that there was 50% reduction in the number of attacks of cold in older women who walked for half-an-hour daily for one year when compared to those who did not exercise.

While the other 62 in the control group went for a 45-minute stretching class only once a week.

There was no change in the dietary habits of the participants. Data concerning cold symptoms or other upper respiratory infections were collected every 3 months in the form of a questionnaire.

"In the final three months, one of 10 exercisers had a cold, but one of three of the non-exercisers did," Ulrich noted.
