HRV - Your Body's Signal for Wellness

What does a “bad” HRV score really mean when you live with adrenal insufficiency?

In this episode, Jake and Rachel take a deep dive into the My Adrenal Life article “Heart Rate Variability & Adrenal Insufficiency: Why the Trend Matters More Than the Number.” Together, they unpack why HRV can be both validating and deeply misleading for people living with adrenal insufficiency.

For many people with primary adrenal insufficiency (Addison’s disease), secondary adrenal insufficiency, tertiary adrenal insufficiency, or steroid-induced adrenal insufficiency, wearable devices often show chronically low HRV. In the general wellness world, that number is usually framed as a sign of poor recovery, high stress, or failing health. But this episode explains why that interpretation does not always fit adrenal insufficiency.

Jake and Rachel break down what heart rate variability actually measures: not heart rate itself, but the variation in timing between beats. In healthy physiology, a higher HRV is often associated with better flexibility in the autonomic nervous system. But adrenal insufficiency changes the whole context.

Because cortisol plays an important role in how the body regulates stress, blood pressure, inflammation, and autonomic balance, people with adrenal insufficiency are often functioning without the smooth hormonal rhythm that supports a more flexible nervous system response. Even with replacement medication, cortisol delivery is still far more static than the body’s natural minute-to-minute regulation. That means HRV may look lower than average even when a person is doing relatively well.

A major theme in the episode is this: the number itself matters less than the trend.

Rather than comparing one person’s HRV to someone else’s, Jake and Rachel explain why it is far more useful to understand your own baseline and watch for patterns over time. A low HRV may simply be part of your normal physiology with adrenal insufficiency. But a sharp drop from your usual baseline over several days may act as an early warning sign that your body is under more strain than usual.

The conversation also explores how HRV can reflect exercise load, illness, missed medication timing, poor recovery, tapering stress, and autonomic compensation. For people with adrenal insufficiency, this can make HRV a useful management tool when used gently and wisely rather than as a harsh scorecard.

Jake and Rachel also discuss the risks of using HRV the wrong way. If a low number becomes a source of panic, self-judgment, or obsessive checking, it can do more harm than good. This episode strongly reinforces that HRV should be used as context, not condemnation. It is not a diagnosis, not a measure of personal worth, and not a replacement for symptoms or medical guidance.

The discussion also touches on exercise and recovery, emphasizing that adrenal insufficiency often responds better to consistency than intensity. When used thoughtfully, HRV trends may help patients recognize when to push a little, when to rest, and when their body may need a gentler day.

At its core, this episode offers something many people with adrenal insufficiency need: permission to stop comparing themselves to healthy populations and start reading their own body more accurately. Your tracker may not fully understand adrenal insufficiency, but your patterns still matter.

If you have ever looked at your HRV and felt discouraged, confused, or frightened, this conversation can help you see the data in a more compassionate and useful way.
