How does breathing affect your heart rate?

The faster you breathe the faster your heart rate gets (more oxygen to pump around) The slower you breathe the slower your heart rate gets. Although correct, this answer does not explain why your heart rate increases. If you are breathing quickly, you are not getting as much oxygen in as if you were breathing normally. Therefore, your heart rate increases because your heart is trying desperately to pump the required oxygen throughout the body that isn't available. For example, if a restaurant is understaffed, the remaining workers will work twice as hard. With not enough oxygen, your heart needs to work harder to deliver the available oxygen. The deeper breaths you take, the slower your heart rate will be, due to the excess of oxygen; your heart won't need to work as hard with lots of oxygen available.
