How does posture affect heart rate?
Lying down is slower than sitting, because of pressure differences in the carotid sinus. Sitting is slower than standing, because of pressure differences in the legs and thighs.
Yes music can affect your heart rate. I am a 7th grader and I did a science fare project on music and your heart rate. Music can and will affect your heart rate. Music with a faster tempo will higher your heart rate adn visa versa. Well im doing a science project on that to and im in sevnth grade and do you need a stethoscope for this?
