    If you’re a music lover, 

you already know that turning on the tunes canhelp calm your nerves, make
stress disappear, pump up your energy levelduring a workout, bring back old
memories, as well as prompt countless other emotions too varied to list.

    Even if you’re not a music aficionado, per se, there are compelling
reasons why you may want to become one, which were recently revealed by a
series of new research.

Music Prompts Numerous Brain Changes Linked to Emotions and 

Abstract Decision Making

    When you listen to music, much more is happening in your body than simple
auditory processing. Music triggers activity in the nucleus accumbens, a part
of your brain that releases the feel-good chemical dopamine and is involved
in forming expectations.

    At the same time, the amygdala, which is involved in processing emotion,
and the prefrontal cortex, which makes possible abstract decision-making, are
also activated, according to new research published in the journal Science.

    Based on the brain activity in certain regions, especially the nucleus
accumbens, captured by an fMRI imager while participants listened to music,
the researchers could predict how much money the listeners were willing to
spend on previously unheard music. As you might suspect, songs that triggered
activity in the emotional and intellectual areas of the brain demanded ahigher

    Interestingly, the study’s lead author noted that your brain learns how
to predict how different pieces of music will unfold using pattern
recognition and prediction, skills that may have been key to our evolutionary

Time reported: 


        “These predictions are culture-dependent and based on experience:
someone raised on rock or Western classical music won’t be able to predict
the course of an Indian raga, for example, and vice versa.

        But if a piece develops in a way that’s both slightly novel and still
in line with our brain’s prediction, we tend to like it a lot. And that, says
[lead researcher] Salimpoor, ‘is because we’ve made a kind of intellectual

        Music may, in other words, tap into a brain mechanism that was key to
our evolutionary progress. The ability to recognize patterns and generalize
from experience, to predict what’s likely to happen in the future — in short,
the ability to imagine — is something humans do far better than any other
animals. It’s what allowed us (aided by the far less glamorous opposable
thumb) to take over the world.”

Why Music Makes Us Feel United


    So far we’ve covered that music is involved in both emotional and
intellectual centers of your brain, but music also has an, almost uncanny,
ability to connect us to one another.

    Separate research published this month showed one reason for why this
might be. When listening to four pieces of classical music they had never
heard before, study participants’ brains reacted in much the same way. Areas
of the brain involved in movement planning, memory and attention all had
similar activation patterns when the participants listened to the same music,
which suggests we may each experience music in similar ways.

    The study’s lead author noted:


        "We spend a lot of time listening to music -- often in groups, and
often in conjunction with synchronized movement and dance … Here,
we've shownfor the first time that despite our individual differences in
musicalexperiences and preferences, classical music elicits a highly
consistentpattern of activity across individuals in several brain structures
including those involved in movement planning, memory and attention."

    Co-author Daniel Levitin, PhD, expanded:


        "It's not our natural tendency to thrust ourselves into a crowd of
20,000 people, but for a Muse concert or a Radiohead concert we'll do it …
There's this unifying force that comes from the music, and we don't get that
from other things."

Music Relieves Anxiety Better Than Drugs and Benefits Premature Babies

    If you want a more concrete example of music’s powers, a meta-analysis by
Levitin and colleagues found some striking benefits of music after reviewing
400 studies. Among the data was one study that revealed listening to music
resulted in less anxiety and lower cortisol levels among patients about to
undergo surgery than taking anti-anxiety drugs. Other evidence showed music
has an impact on antibodies linked to immunity and may lead to higher levels
of bacteria-fighting immune cells.

    Still more research revealed that playing music in the neonatal intensive
care unit (NICU) improved the health of premature babies with respiratory
distress or sepsis. When parents sang to their babies, or sounds mimicking
those in the womb were played, numerous benefits occurred, including changes
in heart rates, sucking behavior and parents’ stress levels. The researchers

        “Entrained with a premature infant’s observed vital signs, sound and
lullaby may improve feeding behaviors and sucking patterns and may increase
prolonged periods of quiet–alert states. Parent-preferred lullabies, sung
live, can enhance bonding, thus decreasing the stress parents associate with
premature infant care.”

    Taken together, the latest research makes a strong case for using music
as a therapeutic tool for babies and adults alike.

Why Music Should be a Part of Your Workouts, Too


    Many people instinctively don a headset linked to their favorite music
when hitting the gym, which makes sense since certain types of music can
motivate you to run faster, or keep going even though you're fatigued, giving
you a better workout. Additionally, research has shown that listening to
music while exercising boosted cognitive levels and verbal fluency skills in
people diagnosed with coronary artery disease (coronary artery disease has
been linked to a decline in cognitive abilities). Signs of improvement in
verbal fluency areas more than doubled after listening to music compared to
that of the non-music session.

    Listening to music while exercising can also improve your performance,
increasing your endurance by 15 percent, and your movement will likely
follow the tempo of the song. For instance, in one study when the music's
tempo slowed, the subjects' exertion level reduced as well. And when the
tempo was increased, their performance followed suit.

    Your body may be simply responding to the beat on a more or less
subconscious level, but the type and tempo of the music you choose while
working out may also influence your conscious motivation.

What Music Is Best?

    When a song gets you energized and rearing to go, you'll know it, and
these are the types of songs you probably naturally add to your workout
playlist.  For that matter, when a song makes you feel relaxed, eases your
anxiety or pain levels, or boosts your mood, you’ll know it too, as selecting
music is a highly personal – and highly intuitive – process. In other words,
only you know the “best” music for you, and that will inevitably change – not
only day to day with your mood but also over time with the different chapters
of your life.

    For now, technology has given us a simple way to harness the power of
music by allowing you to create different playlists for exercising, relaxing,
working and other important aspects of your day so you can instantly access
the right music for your mood or activity. You can also listen to music over
Internet radio using free services like Pandora, which will actually create
stations for you based on your musical tastes.

    Whatever method you choose, making music part of your lifestyle is a
simple yet powerful way to enhance your health and your life.
