Studies Suggest Use of iDevices at Night Harmful to Health: Understanding the Risks


While the research on the effects of exposure to smartphones during the nighttime hours is still in its infancy, there are some basics that we do know. You need to use your phone anytime, for example, scan app ios can be open always but don’t forget to care about yourself.


Exposure to what scientists call the short-wavelength-enriched light of our iPhones and iPads is most detrimental during the last few hours of waking. If you (like me) have a tendency to grab your iDevice late at night after the kids are asleep, or in the wee hours of the morning, it would seem you are only making matters worse. Our body's natural circadian rhythms are thrown off most when we use our iDevices at night, when really, according to these studies, we should be trying to rest and rejuvenate our systems through sleep.

Exposure to this short-wave, blue-spectrum light can significantly suppress melatonin production, which has been tied to incidences of diabetes, vision impairment, cancer, lupus, and obesity, as well as Attention Deficit Disorder and generally lowered immunity.

The use of special blue light filtering glasses and transparent screen protectors, which reduce the amount of blue spectrum light that makes it into our eyes and subsequently our brains, can be helpful for those of us who can't help but be exposed to such light at night.

The drawbacks of exposure to light at night go across the board, it's not just about our iPhones. Televisions, energy-efficient fluorescent bulbs, and e-Readers (like the Kindle) are also culprits when it comes to emitting disruptive light frequencies.

While it may not be the best thing for our natural circadian cycles to sleep with the TV on or even the bedroom light on, the blue spectrum light that our iDevices emit in particular seems to be particularly suspect and even dangerous, especially considering the close proximity these devices are held to our faces. As time goes by, one can't help but wonder; will our beloved iDevices, which seem so indispensable and so convenient, be revealed as greater and greater obstacles to our living a healthy life? An interesting point made by Doctor Richard Hansler, whose research I was reviewing in preparation for this article, was that the blue light emissions from these devices may not change for the better anytime soon. Hansler was pessimistic, observing that changing the amount of blue light would be tantamount to admitting that these screens are actually connected to health problems, and as you might imagine, lawsuits could, and quite likely would ensue.


For more on this topic, I'd encourage anyone interested to read this excellent and thorough article over at Gigaom by Elizabeth Armstrong Moore, which delves deeper into the science and case studies behind the relatively new threat to our well-being that blue light LEDs present. I've also included a short video, featuring Dr. Hansler, in which he talks briefly about the problems of using light at night and offers an optional solution.
