Myth or Fact?
1. A higher HRV always means you are healthier.
MYTH
HRV is highly individual and influenced by many factors. It should be interpreted in context rather than as a simple "higher is better" score.
2. HRV can provide insights into autonomic nervous system function.
FACT
HRV can offer valuable information about autonomic regulation and help identify changes associated with autonomic dysfunction.
3. HRV can be used on its own to diagnose a health condition.
MYTH
HRV is not a standalone diagnostic tool. It should be combined with clinical assessments and other diagnostic measures.
4. Regular physical activity can improve HRV and autonomic function.
FACT
Regular physical activity is associated with improvements in HRV and overall autonomic function.
5. Slow-paced breathing can influence HRV.
FACT
Slow-paced breathing can stimulate vagal activity and is a practical, noninvasive approach that may enhance HRV.
How many did you get right?
HRV is more than a number - context matters.
