Heart rate variability (HRV) is everywhere, and in no space has it made a bigger splash than in sleep medicine. Not only is HRV influenced significantly by sleep, but it is also at the core of wearable sleep technology. In this episode we will:

• Define heart rate variability
• Discuss what increased or decreased heart rate variability means
• List the medical conditions often associated/predicted by changes in HRV
• Characterize how HRV is utilized in sleep medicine
• Contrast how different stages of sleep are reflected in HRV changes and how this is utilized in wearable technology
• Touch upon the factors that positively and negatively influence HRV
