Resting Heart Rate and Heart Rate Variability: What Your Numbers Really Mean
Your resting heart rate and your heart rate variability say a lot about how well your heart is actually working, and most people have never been taught how to read them. In this episode, Dr. Scott Saunders explains what a healthy resting heart rate looks like, why a lower number is often a sign of a stronger heart, and what heart rate variability can tell you about your cardiovascular health.
He clears up common myths, like the idea that you have a limited number of heartbeats, and shows why a perfectly steady beat is not the goal. Then he answers a full hour of viewer questions on sleep, food order, body fat, glucose spikes, exercise intensity, detoxing after chemotherapy, and the supplements he reaches for when blood sugar runs high.
In this episode, Dr. Saunders covers:
- What counts as a healthy resting heart rate, and why athletes often sit in the 40s
- Why a lower resting heart rate usually means a stronger, more efficient heart
- The elephant and hummingbird comparison that makes heart size click
- What heart rate variability is, and why a perfectly even beat is a red flag
- How sleep, stress, and food each move your heart rate and recovery
- Why body fat, glucose spikes, and insulin all change how your heart works
- Whether a high heart rate during exercise is something to worry about
- The blood sugar supplements he reaches for, and how he thinks about each one
