Mind and body: Do music, imagery, touch, or prayer improve cardiac care?
Even the most hard-nosed scientist is likely to agree that there is a strong connection between mind and body. The link between head and heart is particularly strong. Many studies have shown that stress, hostility, anger, depression, and social isolation increase the risk of heart disease and impair recovery from heart attacks. And although scientific proof is less secure, many clinicians have observed that patients who are optimistic, relaxed, and confident seem to come through illness and procedures better than those who are gloomy or anxious.
Hospitals can provide medications to help patients get through taxing tests and treatments, but can they also offer spiritual interventions that may help? It's an important question, but like many areas of alternative medicine, it has not been fully investigated. Two excellent American studies do not completely settle the question of the efficacy of spiritual interventions, but they do serve as models for rigorous scientific approaches to this complex issue.
