Experts: Kindle Helps You Sleep, iPad Causes Insomnia

Illustration for article titled Experts: Kindle Helps You Sleep, iPad Causes Insomnia

According to sleep experts, the iPad's bright LCD display could be hampering your body's ability to create melatonin. Translation: Insomnia. The Kindle and other e-ink devices, on the other hand, won't disrupt your sleep cycle.


The reason for this is the bright light cast into your media-consuming eyes. With the iPad, the LCD display confuses your body, hampers melatonin, and causes sleeplessness. The Kindle, as we all know, has no back light and the impact on your Circadian Rhythm is non-existent.

"The take-home lesson is that insomnia and electronics gadgets emitting light should not [be] mixed before bedtime," UCLA Neurology Clinic Director Alon Avidan, also an associate professor at the university, wrote in an e-mail to the Los Angeles Times. However, "Kindle is better for your sleep."

For some reason I get the impression that Amazon will not be folding the whole "Kindle as a sleeping aid" idea into their marketing materials. [LA Times]



OTOH it might be useful for those who suffer from Seasonal Affective Disorder which is caused by not getting enough light in the winter months.

But I wonder if it is bright enough, the led light arrays that Doctors recommend for this are much brighter than an iPad.

"Light therapy boxes can offer an effective treatment for seasonal affective disorder. Features such as light intensity, safety, cost and style are important considerations when you buy a light box.

By Mayo Clinic staff

A light therapy box is a device used mainly to treat seasonal affective disorder (SAD), a type of depression. Its use is also being studied in other types of depression. Light therapy mimics outdoor light. This causes a biochemical change in your brain that lifts your mood and reduces symptoms of seasonal affective disorder. Light therapy boxes are also known as light boxes, bright light therapy boxes and phototherapy boxes.


Intensity. Look for a light therapy box that provides the right intensity of light when you're a comfortable distance away. Some light boxes offer the preferred 10,000 lux only when you're within a few inches of the box, while others can reach a distance of nearly two feet."


I seriously doubt an iPad puts out 10,000 lux.
