sleeping longer than ten hours might be indicative of other problems that might give cardiologists concern, adds Brooke Aggarwal, Ph.D., a behavioral scientist and clinical health education specialist in the Division of Cardiology at Columbia University Medical Center who was not involved in the study. “Scientists are not totally sure if sleeping too much is a risk to health itself, or if it is simply a marker of increased risk, she tells Inverse.

I used to equates 8 hours of in-bed time to roughly 8 hours in sleep but found that unless I prepare for an ideal sleeping condition beforehand, it was more like 7.25 hours.

Given that I didn't drill down to the study that this article (and other recent articles) are based on, my comment is as much a critique of the journalism as anything else. But by my reading of other studies, 9 hours is in the range of "normal" and this article leaves it in a grey area.
But you are 100% correct, there is more to sleep than simply closing your eyes and preparing for a good nights rest starts as early as the time when you wake up.
