SLEEP 2026 | AHA Life’s Essential 8: sleep recommendations for cardiovascular health

It all started before it was Life’s Essential 8. It was Life’s Simple 7. That was the American Heart Association’s framework for understanding cardiovascular-metabolic health. But it was recently updated. So now there are eight components, which include diet, physical activity, weight, fasting glucose, blood sugar, lipids, smoking, and also now sleep health, where sleep health is now seen as one of the pillars of health alongside some of those others. In addition, the American Heart Association has followed up with a couple of other position statements. One of them defines multidimensional sleep health, describing that sleep health itself is not just one thing, even though Life’s Essential 8 focuses just on sleep duration, saying that people are recommended to get seven or eight or seven to nine hours for optimal health, where more than that or less than that is seen as suboptimal. There are other dimensions of sleep health too. So the multidimensional sleep health paper talks about things like regularity, timing, quality, sleep continuity, sleep architecture, and how sleep impacts your daytime functioning as all being really important dimensions of sleep. And then there’s also another statement from the AHA about circadian health and how internal timing and circadian regulation are also related to heart health. They have specific guidelines, there’s the hours of sleep guidelines, but guidelines for the other dimensions aren’t out yet. They’re still working on them.
