How your fitness watch can predict if you're getting sick

The article from MSN discusses how fitness watches, like those from Fitbit, can predict if you're getting sick by monitoring changes in your heart rate variability (HRV). HRV reflects the variation in time between each heartbeat, which can indicate stress levels, fatigue, and overall health. A study highlighted in the article showed that a significant drop in HRV could precede symptoms of illness by about 24 hours, suggesting that these devices could serve as an early warning system for health issues. This predictive capability is due to the autonomic nervous system's response to infections, which affects HRV. The article also mentions that while this technology shows promise, it's not foolproof, and other factors like sleep quality, physical activity, and stress also influence HRV. Therefore, while fitness watches can provide useful health insights, they should be used in conjunction with other health monitoring practices.
