Listening to music or singing can also decrease levels of stress-related hormone cortisol. Higher levels of cortisol can lead to a decreased immune response.

Abstract
The purpose of this study was to determine the effect of Bach’s Magnificat on emotions, immune, and endocrine parameters in patients of specific infectious lung conditions. Participants (N = 40; 9 men & 31 women) ranging in age from 40 to 75 participated in the study. Patients were randomly allocated to an experimental and control group. During a 3-day period the experimental group received physiotherapy with the selected music, while the control group only received physiotherapy. ANOVA statistics indicate significant changes in the following parameters: POMS-scale, CD4+:CD8+ ratio, cortisol, and cortisol:DHEA ratio. The intervention of music demonstrates communication between the mind and body.
