The Garmin stress score is calculated based on Heart Rate Variability (HRV), a metric that reflects the balance of your autonomic nervous system, the body's control center for involuntary functions. It's a common observation for users to see this score spike after eating, which is a normal physiological response to the demands of digestion.

A reduced heart rate variability (HRV) is associated with an increased risk for numerous conditions, including cardiovascular disease, inflammation, and diabetes. However, a balanced diet rich in specific nutrients is a powerful tool for enhancing your body’s resilience and improving your HRV score over time.

Studies have shown that a diet rich in fruits, vegetables, and healthy fats, such as the Mediterranean diet, is associated with a higher heart rate variability (HRV). This nutritional guide explores what foods help increase HRV and support overall cardiovascular and autonomic nervous system health.

Data from fitness trackers like WHOOP consistently shows that even a single alcoholic drink can cause an average drop in heart rate variability (HRV), sometimes by as much as 22 milliseconds the following day. This dip isn't just a fleeting anomaly; it reveals a significant disturbance in your body's most vital regulatory systems, explaining why alcohol is so bad for HRV.

According to a 2020 review in the journal *Advances in Nutrition*, there is accumulating evidence suggesting deficiencies in certain micronutrients, such as vitamins D and B12, are associated with reduced heart rate variability (HRV). The complex relationship between diet, vitamins, and HRV is a growing area of research, offering insight into how nutrition can influence the autonomic nervous system and overall well-being.

According to official WHOOP guidelines, consistently hydrating by consuming roughly one ounce of water per pound of body weight can significantly improve your recovery metrics, including Heart Rate Variability (HRV). The question of 'What is the hydration goal for WHOOP?' is directly tied to achieving better overall physiological performance and health.

A 2022 review published in the *Journal of the American College of Cardiology* highlighted the growing link between certain micronutrients and heart health. This has sparked significant interest in what supplements improve HRV, a crucial biomarker for stress and recovery.

A growing body of research suggests that certain forms of fasting can positively influence the body's autonomic nervous system, leading to improvements in heart rate variability (HRV). This deep dive explores the physiological mechanisms, research findings, and practical considerations for those interested in knowing how can fasting improve HRV and overall cardiovascular resilience.

Research consistently shows that eating initiates a complex physiological process, often causing a temporary shift in the body's autonomic nervous system. This shift is a key reason why heart rate variability (HRV) can go down after eating, reflecting the body's reallocation of resources to digestion.

Research has shown that chronic inflammation, often fueled by poor dietary choices, can lead to decreased heart rate variability (HRV), a key metric for overall health. This critical measurement of your autonomic nervous system reveals exactly how **can diet influence HRV** and your body's resilience to stress.
