HealthDay (7/17, Thompson) reports people with insomnia “have a much higher risk for depression if they have chronic inflammation, a new sleep lab experiment says.” Researchers found that “seniors with insomnia were three times as likely to report symptoms of depression if they’d been dosed with a substance that promotes inflammation.” One researcher said, “Insomnia not only robs older adults of rest but also primes their immune system to make them uniquely vulnerable to depression when faced with inflammation.” The findings were published in JAMA Psychiatry.
