Will the iPad mini and Night Shift make the ereader obsolete?

A recent eMarketer study has shown that ebook readers are holding their own, but that was before Apple’s changes.

The iOS 9.3 update brought the “Night Shift” feature to iPhones and iPads and comes with the controversial claim that it has reduced the amount of blue light emitted by the mobile devices and may, therefore, help to push the ereader further toward being obsolete.

The reason is that while Apple says its devices may no longer interrupt sleep patterns, ebook readers still might.

The design of the “Night Shift” is meant to decrease the blue light emitted by the device. Those wavelengths of light are often blamed for disturbing people’s ability to sleep, so by removing them, the thought is that it will stop people from harming their sleep cycles through the use of tablets at bedtime. With this in mind, some have predicted that the use of the ereader, a device that is not backlit and that does not emit any blue light, will decline.

Some people have been using an ereader to read ebooks at bedtime in order to avoid wakefulness problems related to tablet use.

Will the eReader become obsoleteOverall, most doctors and sleep specialists recommend that patients stop using any kinds of mobile devices for an hour to 90 minutes before they go to bed. That is meant to decrease exposure to blue light but also to the stimulation these gadgets can bring with their use. Many doctors also recommend that patients use only dim lighting throughout that same span of time in order to help to encourage the production of melatonin (a sleep-promoting hormone that is light sensitive).

For that reason, eink displays from dedicated ereaders have been seen as great ways to take advantage of a certain limited amount of internet connectivity, as well as the comfortable ability to read an ebook, such as a favorite young adult fiction novel or the latest murder mystery in a series you’re enjoying.

So far, eink ereader displays haven’t been connected with sleep struggles and have been very appealing to people who are trying their best to give themselves a restful night of sleep. What has yet to be seen is whether the Night Shift in combination with the iPad mini from Apple will be enough to replace ereaders by providing a full tablet experience without the blue light exposure.

Study shows that tablet computers are causing insomnia

Though it has long been believed that light interrupts sleep, this research focused specifically on mobile device screens.

Scientists and doctors have known for many years that exposure to light can interrupt a person’s natural sleep patterns and make it harder to obtain the rest we need, but recently the light from tablet computers was put to the test by a team of researchers from the University of Bergen.

What they found was that people who use tablets and other mobile devices causes harm even when used in the dark.

The researchers looked into the impact of using tablet computers at bedtime when compared to reading a traditional print book. What the scientists discovered was that after reading a tablet screen for only 30 minutes while in bed, a negative impact on sleep can occur. The results of this study were published within the Sleep Medicine journal. The intention of the research was to determine whether the backlighting of the screens of mobile devices actually had a meaningful impact on the quality of sleep a user would receive.

The researchers compared the use of tablet computers with the results from people reading print books.

Tablet Computers Study - InsomniaThe study involved the participation of 16 students with an average age of 25.1 years. The research participants were permitted to sleep in their own homes and beds in order to ensure that the results were not compromised by an alteration in the participant’s sleep environment. The researchers then used a polysomnography tool in order to be able to detect sleep disorders in any of the participants. Before the study, none of the participants suffered from sleep struggles.

When the participants read from print books, the problem with sleep struggles was deemed nonexistent among the participants who already did not have problems with insomnia.

On the other hand, the tablet computers appeared to have an effect on the level of sleepiness of the users. It is suspected that the light emitted from the device screen may have played a role in this impact. That said, it’s important to note that while it may have taken more time for tablet users to doze off, the duration of sleep was the same regardless of the use of a digital screen or a print book.
