Music is capable of a number of health benefits including lowering stress levels, raising states of consciousness, changing moods, accessing different states of mind, developing the brain and is useful in meditation -which has a ton of health benefits.
“I think music in itself is healing. It’s an explosive expression of humanity. It’s something we are all touched by. No matter what culture we’re from, everyone loves music.” ~ Billy Joel
Keeps an aging brain healthy
Research has shown that having musical training and listening to or playing music in old age can help keep the brain healthy especially as it ages. Since listening to music is like exercising the brain, one can expect the benefits of better memory and mental sharpness as they age.
Even people who have some form of brain damage can regain partial or full access to memories (depending on severity) by listening to music, as listening can help draw on old memories and neurological patterns due to the fact that the rhythm and sounds of music stay within the core of the mind for a long time.
Music Makes You Happier
As mentioned before, music has the power to do so much. It can make you feel happy, sad, excited or even pumped up. Listening to music that hits you in a special way causes your brain to release dopamine which is known as a feel good chemical. It causes us to feel emotions like happiness, excitement, joy, etc. Listening to music provides us with the same burst of happiness that we would get from eating a piece of chocolate, sex or certain drugs.
Another study showed that music with a quick tempo played in a major key made people feel happy, while music with a slow tempo in a minor key more easily led to feelings of sadness.
Heartbeat, Pulse Rate & Blood Pressure
‘We listen to music with our muscles.’ Nietzsche
Studies have shown that music strengthens the heart and improves the recovery time of patients who were suffering from heart disease.
Regardless of the genre of music, listening to your favorite music releases endorphins in the brain that help to improve vascular health. It has been seen that both men and women who listened to music soon after cardiac surgery were much less anxious and even reported having less pain as opposed to those who rested quietly.
An observation made at Massachusetts General Hospital, found that heart patients confined to a bed that listened to music for 30 minutes had lower blood pressure, slower heart rates, and less distress than those who didn’t listen to music.
Improves Sleep Quality
Some of the most common things to interfere with sleep are stress and anxiety (heart rates.) Since music has the ability to affect both in a positive way, research has found that listening to music at various times promotes better sleep patterns for people and even created more restful sleeps. In some cases music might even be able to be used to effectively treat insomnia.
Boosts Your Immune System & Reduces Pain
Research has shown that music is capable of reducing levels of the stress hormone cortisol, which is responsible for weakening the immune system, increasing risk of heart disease, interfering with learning and memory, lowering bone density, blood pressure, etc.  Research found that by listening to just 50 minutes of uplifting music the levels of antibodies in the human body increases. While different types of music were not studied, it is important one listens to music they enjoy as personal preference of music does have an effect on overall physical effects.
Reduces Depression & Anxiety
Researchers from Drexel University found that cancer patients who either listened to music or worked with a music therapist experienced a reduction in anxiety, had better blood pressure levels and improved moods. Music can have positive effects on the psyche, mood, pain and quality of life as well.
