|Chronic Insomnia Linked To Depression, Anxiety
By Amy Norton
NEW YORK (Reuters Health) For some people, chronic insomnia may be a sign of broader mental health problems like depression and anxiety, according to a new study. In surveys of more than 25,000 Norwegian adults, researchers found that those with chronic insomnia were more likely to also be suffering from depression or an anxiety disorder. What's more, people who reported insomnia during the first wave of the survey were at increased risk of having an anxiety disorder during the second wave, conducted a decade later.
