How does music help relieve stress? In this video, Neuroscientist Dr. Daniel Levitin explains how listening to music allows your mind to wander. Stress is bad for your brain because it releases excess amounts of cortisol and adrenaline, which can lead to a weakening of the immune system. Music counteracts this by allowing your brain to enter the default mode, where it can wander. This effectively hits a reset button in your brain by forcing it to take a break!
