Basically meaning that my sleep schedule is going to kill me!
On a more serious note, some studies have analyzed that there may be a link between insomnia & heart disease.
On the other hand, there has been some firm link to hypertension & atherosclerosis, which for me as a Med student makes sense, as it may be more related to the stress caused by Insomnia rather than Insomnia itself.
However, the problem is that (as the articles say), there is a lack of consensus to "how is insomnia defined".
In any case, it would be interesting!
