What Is Cardiac Coherence?
Cardiac coherence (CC) is a physiological parameter that tells you how well your heart, lungs, endocrine system, and brain are synchronized. It’s a measure of the order, stability, and harmony in the oscillatory outputs of your body’s regulatory systems during any period of time.
Why Is Cardiac Coherence Important?
CC reflects your psychophysical and emotional state and determines your ability to resist mental, emotional, and physical stressors. During sleep, typical values for the CC in adults are between 2 and 10. Generally, the higher the average CC value is during sleep, the better prepared you are to manage the stressful situations to which your body and mind are exposed.
How Is Cardiac Coherence Measured?
It’s measured through heart rate variability and breathing analysis. Ivy measures CC during sleep and can measure only when you’re still enough. Missing data means your body movement was too intense for Ivy to detect your CC or that you're wearing your Ivy too loosely.
What Do My Statistics Mean?
Average - The number here expresses the central value in your set of CC data points that have been collected during your sleep cycle. This is the typical value for that particular sleep cycle and can be used to make comparisons between days. The higher the average CC value is during sleep, the better prepared you are to manage stressful situations to which your body and mind are exposed.
Minimum - This is the smallest value in your given set of CC data points collected during the sleep cycle. It shows the moment during sleep when your body was the least peaceful and rested.
Maximum - This is the highest value in your given set of CC data points collected during the sleep cycle. It shows the moment during sleep when your body was at its most peaceful and rested state.
What Does the Graph Mean?
The graph shows you how your CC data changes throughout your sleep cycle. The sleep period, when data is collected, is divided into hourly intervals. Each point on the graph represents the average value for a particular interval and the box around the data points represents its min-max range.
