Title: Meditation or Exercise for Preventing Acute Respiratory Infection (MEPARI-2)
Brief Summary: The primary goal of this project is to determine whether behavioral training in mindfulness meditation or moderate intensity sustained exercise will lead to reductions in acute respiratory infection (ARI) illness, such as common cold and influenza like illness. Specifically, this project aims to:

1. Determine whether an 8-week training program in mindfulness meditation, as compared to the control group, will lead to significant reductions in incidence, duration, and severity of ARI illness.
2. Determine whether an 8-week training program in moderate intensity sustained exercise, as compared to the control group, will lead to reductions in incidence, duration, and severity of ARI illness.
3. Assess whether any observed reductions in ARI illness are accompanied by fewer ARI-related health care visits and less time lost to productive work (reduced absenteeism).
4. Compare the potential benefits of mindfulness meditation to those from moderate intensity sustained exercise.
5. Discern potential mediating factors and causal pathways that might help explain how these interventions lead to improved ARI illness-related outcomes.

The investigators' preliminary findings suggest substantial benefit of these interventions in terms of reduced incidence, duration and severity of ARI illness, with corresponding reductions in days of work lost to illness. If the proposed research confirms these findings, there will be major implications for public and private health-related policy and practice, as well as for scientific knowledge regarding health maintenance and disease prevention.
