A new study reveals cause for concern about the Daylight Savings Time change and teen brains in the spring.
According to the study published in the Journal of Clinical Sleep Medicine, the loss of sleep was associated with lapses of attention, longer reaction times, and increased daytime sleepiness. It raises concerns about teen driving safety.
“For many years now, sleep researchers have been concerned about sleep deprivation in adolescents. This study unveils a potential additional factor that may further restrict their sleep in the early spring,” said principal investigator Dr. Ana Krieger of the Weill Cornell Center for Sleep Medicine at NewYork-Presbyterian Hospital.
After the change to daylight savings time in March, the research team studied 35 high school students on weeknights. The teens slept on average 32 minutes less per night than before the time change. According to the American Academy of Sleep Medicine, teens should get at least nine hours of sleep a night. These teens got 7 hours, 19 minutes.
