Final answer:
Sleeping problems are indeed 2-3 times more common in people with mental illness, with conditions like insomnia being frequent among those with various mental health issues.
Step-by-step explanation:
It is true that sleeping problems are 2-3 times more common in people who suffer from a mental illness. Mental illnesses, such as major depression, bipolar disorder, anxiety disorders, and others, often have a significant impact on sleep patterns, leading to disorders like insomnia. Individuals with these conditions frequently experience difficulties falling or staying asleep, and the presence of a mental illness can exacerbate the severity and frequency of sleep disturbances. The link between sleep disorders and mental health is recognized by the American Psychiatric Association in the Diagnostic and Statistical Manual of Mental Disorders (DSM), which outlines how these conditions are often interconnected.
