Longevity research is finding that certain biomarkers can signal disease years before symptoms appear, and that small, measurable shifts in these numbers can meaningfully extend both how long and how well you live. Researchers have found that a higher resting heart rate is an independent risk factor for mortality, as it can be elevated for various reasons, including diabetes, cardiovascular disease, chronic obstructive pulmonary disease, and many other chronic conditions. The best predictor of outcomes is our nighttime resting heart rate because it’s more stable and not affected by our daily activities and stress.
