Time change leads to sleep disruption for many

For people with insomnia, the extra hour provided by the end of Daylight Savings Time usually does not translate into an additional hour of quality sleep. Instead, the time change (both in fall and spring) often further disrupts circadian rhythms (which play a major role in regulating sleep) for people already struggling with sleep problems. Roseanne Armitage, Ph.D., director of U-M’s Sleep & Chronophysiology Lab and a professor of psychiatry, was quoted in an Ottawa Citizen article on the topic.
