Researchers find direct link between bedtime media device use & inadequate sleep

Children and teenagers who use mobile devices like smartphones, tablets and computers at night lose sleep time as well as sleep quality, a new research cautioned.

Teachers often face classrooms filled with yawning students. The new research found that students yawn in classroom due sleep depreciation caused by mobile devices that keep them awake till late in the night.

Dr. Ben Carter of King's College London and colleagues analyzed hundreds of studies conducted between January 2011 and June 2015. They selected twenty research reports involving 125,198 kids with an average age of 14½ years.

They found a strong and consistent correlation between bedtime media device use and inadequate sleep, poor sleep quality as well as excessive daytime sleepiness.

Dr. Sujay Kansagra, the director of the pediatric neurology sleep medicine program at Duke University Medical Center, said, “Sleep is vital for children. We know that sleep plays a crucial role in brain development, memory, self-regulation, attention, immune function, cardiovascular health and much more.”

Light emitted from devices like smartphones and tablets may also affect the person’s circadian rhythm -- the internal clock that times biological processes, including temperature of the body and release of hormones.

The findings of the new study were detailed in the Oct. 31st edition of the American Medical Association’s JAMA Pediatrics journal.
