Research has shown that singing increases levels of immunoglobulin A, a vital antibody that plays a frontline role in defending the body against infection.
Whether performed solo or in a group, singing has also been linked to a reduction in cortisol, the body’s primary stress hormone. Since elevated cortisol can weaken immune response, lowering it through activities like singing may help the body stay more resilient against illness.
Studies from institutions such as the University of Oxford support the idea that singing offers measurable physiological benefits alongside emotional well-being.
Participants often report feeling happier and more connected after singing, and now science confirms there are biological reasons behind that boost. With its ability to simultaneously reduce stress and strengthen immune defense, singing emerges as a simple yet powerful practice for improving both mental and physical health.
