Concord-Carlisle, Massachusetts

Concord-Carlisle forms a start time committee.

“Dr. Charles Czeisler, chief of the Division of Sleep and Circadian Disorders at Brigham and Women’s Hospital, told The Concord Journal last month that earlier start times have resulted in a loss of 50 hours of sleep monthly for students, which “induces harmful biological effects,” including a reduction in a sleep stage called Rapid Eye Movement (REM), when students integrate new information from the day’s learning with previous learning. Other harmful effects, according to Czeisler, include higher risk of traffic accidents because students are drowsy, physiological effects like chronic sleep deficiency, which can lead to higher glucose levels that increase the risk of diabetes and high blood pressure, and mental health issues such as compromised attention spans, increased levels of distractibility, higher risk of substance abuse and greater risk of depression and suicide.”
