Factors and Causes Affecting HRV

Understanding Heart Rate Variability (HRV) is crucial for assessing overall well-being and stress levels. HRV measures the variation in time between each heartbeat, which is influenced by the autonomic nervous system's balance. Here's a look at key factors and causes affecting HRV:

  • Stress: Chronic or acute stress negatively impacts HRV, reducing its variability.
  • Sleep Quality: Poor sleep can lower HRV, indicating that the body isn't resting properly.
  • Physical Activity: Regular moderate exercise improves HRV, while overtraining can decrease it.
  • Diet and Hydration: A balanced diet and proper hydration support higher HRV.
  • Cardiovascular Diseases: Conditions like hypertension or heart disease can lead to decreased HRV.
  • Mental health Issues: Anxiety and depression are linked with lower HRV values.

This overview highlights the association between lifestyle choices, health conditions, and HRV. Changes in HRV can reflect the body’s response to various internal and external factors.
