To be fair, it's a press release about a scientific study, not a self-help blog post, but you raise a good point when you say that poor sleep patterns "just happen to me." I've always valued sleep, but often in my life, my sleep has been disrupted because of stress, anxiety, and depression. The article says the researchers controlled for "other factors that may have heightened the risk of dying, including lower socioeconomic status, smoking and alcohol consumption and other medical conditions," but did they control for stress? The author quoted in the press release seems quite confident that we can eliminate these bad mortality outcomes by teaching people to sleep better, but another way to interpret the result is that any factor that increases stress will damage health and also disrupt sleep. I also wonder where the author gets his confidence that "good sleep hygiene" can have such a great impact. How does he assume that "sleep hygiene" will overcome the factors causing poor sleep? Does he really believe that they've controlled for every other factor and isolated "sleep hygiene" as the root cause? My personal experience says that what he calls "sleep hygiene" helps a little bit, but it doesn't overcome the effects of stress or poor life management due to depression, and those factors have to be managed directly.
