According to Dr. Daniel Levitin, McGill University psychologist and author of the book This Is Your Brain on Music, playing or listening to music "increases the body's production of the antibody immunoglobulin A and natural killer cells" that improve immune system function. It also lowers your cortisol levels, reducing stress.
In other words, music makes us healthier. But unless you're a musician, you're probably not wetting a reed, rosining a bow, or tuning your guitar when you get home from the office. Instead, you're streaming a playlist or putting on a record. The issue is where you listen to your music.
Without a dedicated space for listening, you might be sharing your music with others – kids playing games? spouse reading a magazine? – who aren't as into your tunes as you are. You'll have to keep the volume low or try to ignore the ambient sounds.
And it's hard to reap the benefits of music when you're fighting distractions just to hear it. Its also a well known fact that the performance of any audio system largely depends on the room in which the system is set up.
Try to imagine a music system in a bathroom. It won’t work.
