Heart rate variability (HRV) analysis is a method for assessing the changes in intervals between heartbeats. It measures how much the heart rhythm varies in response to different physiological and external factors such as stress, physical activity, or rest. The higher the variability, the better the body's ability to adapt to changes. Read more about the Health Monitor

HRV is considered an important indicator of overall health, as it is closely linked to the functioning of the autonomic nervous system, which regulates key bodily processes (heart rate, breathing, blood pressure). High heart rate variability indicates good adaptability and resilience to stress, while low variability may signal fatigue, stress, or health issues.

In everyday life, HRV is useful for monitoring physical and mental well-being, helping to track stress levels, recovery after exercise, and sleep quality. Modern health monitoring devices are based on HRV analysis, providing valuable insights into the body's condition in a short time, often detecting health changes before symptoms appear. This kind of monitoring helps adjust lifestyle habits and reduce the risk of developing illnesses.
