It turns out your difficulty getting to sleep could be related to reading on your tablet at night.
A study published by Proceedings of the National Academy of Sciences found that reading before bed on light-emitting electronic devices extends the time it takes to fall asleep, suppresses melatonin levels and even decreases alertness in the morning.
Researchers at Boston’s Brigham and Women’s Hospital monitored the heart rates and brain waves of 12 adults who spent five days reading paperback or hardcover books, then five days reading from electronic devices. Blood levels revealed that melatonin—the sleep-promoting hormone—was lower in those who read from electronic devices.
“In the LE-eBook condition, participants averaged nearly 10 minutes longer to fall asleep than in the print-book condition,” the study reported. “Participants also had significantly less rapid eye movement (REM) sleep following the LE-eBook condition, reflecting a lower average rate of accumulation of REM sleep during sleep.”
The study concluded it’s best to read SUCCESS in print at night rather than from our app.
