Keeping heart healthy: How does breathing affect your heart rate and cause heart rate variability
In this video series on keeping herat healthy, Dr Lim, author of Keeping Your Heart Healthy, part of the Penguin Life Experts Series, demonstrates with a 30 second ECG recording on his Apple Watch Series 4, how merely slowing your breath (to a 6 sec cycle in and 6 sec cycle out) can have a profound impact on heart rate variations. In this example, Dr Lim was able ot lower his herat rate by 22 beats per minute at the end of a short 30 second breathing exercise.
In general, we should learn to start breathing in this healthy and relaxing way more often - this will have a huge impact, not only on heart rate variability patterns, but allow us to destress, and emotionally regulate better too
