One study found that babies as young as five months old reacted to happy songs, while by nine months they recognized and were affected by sad songs [source: LiveScience]. Physiological states brought on by music only intensify as we grow. 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 [source: Leutwyler].
In this case, 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 [sources: Lloyd, Wiley-Blackwell]. Researchers at Cal State University found that hospitalized children were happier during music therapy, in which they could experiment with maracas and bells while a leader played the guitar, than during play therapy, when their options were toys and puzzles [source: Hendon and Bohon]. 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 [sources: Parker-Pope,
