Healthy lifespans are improving, do we know why?

Understanding the Improvement in Disability Free Life Expectancy In the U.S. Elderly Population

If you want to know the reason behind the improvement of healthy life expectancy in US, then you have to read this chapter.  Three fundamental conclusions:
First, we show that healthy life increased measurably in the US between 1992 and 2008. Years of healthy life expectancy at age 65 increased by 1.8 years over that time period, while disabled life expectancy fell by 0.5 years. Second, we identify the medical conditions that contribute the most to changes in healthy life expectancy. The largest improvements in healthy life expectancy come from reduced incidence and improved functioning for those with cardiovascular disease and vision problems. Together, these conditions account for 63 percent of the improvement in disability-free life expectancy. Third and more speculatively, we explore the role of medical treatments in the improvements for these two conditions. We estimate that improved medical care is likely responsible for a significant part of the cardiovascular and vision-related extension of healthy life.
And this is what I said two years ago in this post with Catalonia data:
Fortunately, new data about recent trends has been published and we can confirm that has increased over a period of 7 years, between 2005 and 2012 from 63 to 65.7 years for men and from 60.6 years  to 66.1 for women . In women the proportion of years lived in good health has gone up by 5 percentage points, from 72 to 77 % in men and has increased only one point from 81 to 82 %. In any case, in marginal and in absolute terms there is a substantial improvement . Nobody would have been able to foresee changes of this magnitude.
Unfortunately we don't know why.
