Studies Suggest Use of iDevices at Night Harmful to Health
Did you just score a new iPhone or iPad over the holidays? How often do you use scan app ios? Well, not to rain on your parade, but evidence continues to mount that these devices aren't quite as safe for us as you might think. Don't get me wrong, I love my iPhone and my iPad, but they are a double-edged sword. Previously I've written about the potentially dangerous side-effects of harmful EMFs that these pocket-sized microwaves emit. I've also written about steps that those concerned about the effects of constant low-level radiation exposure can take to mitigate these effects. Now new scientific studies are again calling into question the safety of these devices, which for many of us, are practically an extension of our body.
This time it's not the electromagnetic frequencies that are being questioned, but rather, the disruptive effects on our bodies of the blue spectrum light these devices give off; a topic especially relevant for those of us who keep our iDevices handy through the night.
The awareness within the scientific community of the detrimental effects of being exposed to electric light at night is certainly nothing new. Going back to a 2012 Harvard study, it was determined that the same super bright and extremely hot blue spectrum light that enables us to see our iDevice's brilliant, high-resolution screens also significantly disrupts our sleep patterns and melatonin production. The evidence presented in the 2012 Harvard study, and more recently, the evidence presented in a 2014 study conducted by the National Academy of Science, confirms the sad truth that our continual exposure to our iDevice's display can have a serious downside.
In September 2014, the National Academy of Science issued the following statement: "We found that the use of these devices before bedtime prolongs the time it takes to fall asleep, delays the circadian clock, suppresses levels of the sleep-promoting hormone melatonin, reduces the amount and delays the timing of REM sleep, and reduces alertness the following morning. The use of light-emitting devices immediately before bedtime also increases alertness at that time, which may lead users to delay bedtime at home. Overall, we found that the use of portable light-emitting devices immediately before bedtime has biological effects that may perpetuate sleep deficiency and disrupt circadian rhythms, both of which can have adverse impacts on performance, health, and safety."
