One of the most widely studied biometric effects of music is its ability to alter heart rate. Listening to music with a fast tempo can increase heart rate, while music with a slower tempo can have the opposite effect. This finding is supported by a review published in the Journal of Advanced Nursing, which found that music with a tempo of around 60-80 beats per minute can increase heart rate variability, a measure of the body’s ability to adapt to stress.
In addition to its effects on heart rate, music has also been shown to affect blood pressure. A study published in the Journal of Human Hypertension found that listening to music can lower blood pressure in individuals with hypertension. Similarly, a review published in the journal Music & Medicine found that music can reduce blood pressure in healthy individuals as well.
Music can also alter brain waves, with certain types of music being able to induce specific brain wave patterns. For example, a study published in the journal Frontiers in Human Neuroscience found that listening to music with a strong beat can increase alpha brain waves, which are associated with relaxation. Other research has found that listening to music can increase the production of the neurotransmitter dopamine, which is involved in the regulation of mood and emotion.
In conclusion, music has a powerful effect on various biometric measures, including heart rate, blood pressure, and brain waves. These effects can have potential benefits for physical and mental health, including the ability to reduce stress and promote relaxation. Further research is needed to fully understand the mechanisms behind these effects and to determine the optimal types of music for different health outcomes.
