Health Alert: Tablets & E-Readers May Compromise Sleep Quality. Light emitted by electronic devices, like e-readers and tablets, may disrupt sleep if used in the hours just before bedtime. Harvard researchers found that individuals using these types of devices felt less sleepy and took longer to fall asleep than when they read a regular printed book. After using a light-emitting electronic device before bed, study participants also found it harder to wake up and become fully alert the following morning. The researchers assert that the light emitted from such devices suppresses the production of melatonin, a hormone that helps regulate the bodys sleep-wake cycle.
