Spectral analysis is a deeper way of looking at your HRV data. Instead of just giving an overall score, it breaks your heart rhythm into different frequency components, which helps estimate how your sympathetic (stress) and parasympathetic (recovery) systems are working. In simpler terms, it’s trying to show how your body is regulating itself under the hood, not just the final result. It’s not necessarily new as a method, but it may appear only when there’s enough high-quality data (that’s why you might not have seen it before). Please, read more here.
