Happy music, usually featuring a fast tempo and written in a major key, can cause a person to breathe faster, a physical sign of happiness. Similarly, sad music, which tends to be in the minor keys and very slow, causes a slowing of the pulse and a rise in blood pressure.
Knowing that music has this impact on the body may eventually influence treatment and care for a wealth of patients. For example, music has been found to boost the immune systems of patients after surgeries, lower stress in pregnant women and decrease the blood pressure and heart rate in cardiac patients, thus reducing complications from cardiac surgery.
Music therapy has also proven to be more effective than other types of therapies in patients suffering from depression, and it’s been shown to lower levels of anxiety and loneliness in the elderly. However, it is also worth to noting that too much music could be too much of a good thing.
Since music triggers reward systems in our brains much like drugs do, music could also become an addiction that becomes impossible to feed. Having music around us constantly — from department stores to elevators to our headphones — could numb us to its effects. Unplugging that iPod every now and then might just help your favorite song sound sweeter later on.
