If you are a shift worker or someone who has short sleep chronically, this could be a reason that these groups have a higher incidence of cardiovascular disease and diabetes and all sorts of things. It could be related to sleep duration.Heart rate variability has been shown to be a good measure of cardiovascular risk.

Heart rate variability is quite simply the variation in the interbeat intervals of our heart,” “It is a very sensitive index of the health of our body’s stress response systems. It’s one way to measure the health and fitness of the fight or flight system.

When the body experiences stress, for example, from exercise or extreme temperatures, — it can maintain a stable blood pressure and constant body temperature in part by dialing the heart rate up or down. And HRV plays an important role in maintaining this balance. A familiar related problem is in driving. To get to a destination despite varying weather and traffic conditions, any driver — even a robotic one — will change factors such as acceleration, braking, steering, and wipers. If these factors suddenly became frozen and unchangeable while the car was still moving, it would be a nearly certain predictor that a crash was imminent. Similarly, loss of heart rate variability predicts some kind of malfunction or ‘crash,’ often before there are any other indications.

Whenever you want to nurture innovation, you need to have metrics… The reason HRV was chosen was… one, we have decades worth of heart rate variability data…. there is good cohort data, population level data, that suggests that declining HRV is also due to a chronologic age…. [and] unlike most biomarkers in health, HRV can be measured continuously, contextually. You can measure it for 24 hours.
