An interesting recent study published in Lancet Psychiatry found that a web-based program of cognitive behavioral could improve sleep in some people.
There are several weaknesses in this study – online registration, self-reporting, large drop-out rate – but still, the results are encouraging in that insomnia is very prevalent and there are simply not enough psychologists and sleep therapists (never will be) to handle the mass of humanity who might benefit from such therapy so online programs would be a great benefit to the sleepless among us.
Plus, a DIY online program should also presumably not be too expensive: win, win, win all around.
Interestingly, this study also found that some study participants reported that certain symptoms that are often associated with mental illness – such as paranoia and hallucinations – also improved with better sleep, leading to the obvious question as to whether some forms of milder mental illness might not also be at least partly linked to poor sleep.
As an aside, however, I think it’s also important to add that in these Trumpian times, paranoia may not actually be a sign of mental illness; rather, it may be a sign of mental health.
