When you inhale, your diaphragm moves down, expanding your lungs and allowing your heart to fill more, which can slow blood flow and trigger a response to speed up your heart rate.

To speed up your heart rate, inhale longer and more vigorously than you exhale; conversely, to slow your heart rate, make your exhales longer and more vigorous than your inhales.
