Over the past fifty years, sleep duration has fallen by around 1.5-2 hours. This should be all the more concerning since a study published in the European Heart Journal found that short sleepers were 48% likelier to develop coronary heart disease within 7-25 years, and 15% likelier to suffer from a stroke during the same period.
It's worth mentioning that researchers don't know why there appears to be a higher risk of heart disease in those who don't get enough sleep. Right now, the link isn't completely understood - those who slept too long were also found to be at a higher risk of heart problems.
This is a new area of research, yet an increasing number of studies are finding a link between heart health and lack of sleep. Let's hope we see the release of more results and information sooner rather than later. Perhaps they'll be the trigger we need to change society's general ignorance towards insomnia.
