Dr. Daniel Levitin is a prominent psychologist who studies the neuroscience of music and its benefits to our brains. To Doctor Levitin, listening to music has much more benefits than we think, listening to music not only feels good, but also can translate into physiological benefit.
Researchers working along with Doctor Levitin studied patients who were about to have a procedure. Participants were asked to either listen to music or take pills. Scientists tracked patient's ratings of their own worrying, as well as the levels of Cortisol.
The results were fascinating; the participants who decided to listen to music were more relaxed and less stressed than their counterparts who took medication.
