Why are Dilated Blood Vessels Good?
When your blood vessels are dilated, the vessel walls are thinner, allowing for more oxygen and nutrients to pass through to the muscles. This of course gives the muscles what they need to function. Additionally, since the heart doesn’t have to work harder to push more blood through constricted blood vessels to feed the muscles, dilated blood vessels lowers blood pressure and heart rate. Lower blood pressure and heart rate leads to other benefits: the body is able to exercise for longer periods of time; the body is able to work harder; the body feels relaxed.
