As we approach the changing of our clocks for daylight saving time on Sunday, March 12, University of Minnesota Medical School expert Michael Howell speaks about how the time change can impact sleep.

Michael Howell, MD
“Sleep is critically important to our brain and body health, yet most people don’t sleep well. This has consequences ranging from missed free throws to cancer. The hour of sleep loss during the change into daylight saving time is linked to car accidents and heart attacks, providing a little glimpse into the importance of sleep.”

Specializing in sleep disorders, Dr. Howell is a professor at the U of M Medical School and is the medical director of M Health Fairview’s Sleep Performance Training program for Athletes. His clinical interests include sleepwalking and related disorders such as REM sleep behavior disorder, sleep-related eating disorder, sleep seizures and other violent sleep behaviors.
