E-readers, phones and tablets are not advised to be used before sleeping


That means a such habit is disrupting sleep and will turn in time to affect health. The melatonin suppression is linked to the light emitted by e-reader. We should be advising people to minimize their [light-emitting e-reader] use in the evening, particularly teenagers who are a group that are using their phones and tablets late in to the evening” is the advice of Dr Victoria Revell, who researches the impact of light on the body at the University of Surrey. Even more, “people who already have a delayed body clock are delaying themselves much further and that is a very important message,” she added. Last year,Charles Czeisler, a professor of sleep medicine at Harvard Medical School, found that around 90 percent of Americans use some kind of electronic device within the hour before bed.
