“If you are buying a new iPhone, don’t use it in bed — and not just because nighttime smartphone use messes up your sleep cycle.
The blue light from personal electronic devices has also been linked to serious physical and mental health problems.
Blue light is part of the full light spectrum, which means we’re exposed to it by the sun every day. However, nighttime exposure to that light, which is emitted at high levels by smartphones, tablets, laptops, and other LED screens, may be damaging your vision. It also suppresses production of the hormone melatonin, which throws off your body’s natural sleep cues.
When your melatonin levels and sleep cycle go haywire, your risk goes up for a wide range of ailments, from depression to cancer.
Our various personal electronic devices emit blue light because it’s so bright. That’s the only way we can see those screens when the sun is shining. But we’ve started to have regular close-up nighttime exposure to this light only in the past 10 or 20 years, as a recent Gigaom story on the topic notes.
Now we’re really starting to see the consequences.
Blue Light At Night
1. The damage that this habit does to our eyes alone is both significant and surprising. Direct exposure to blue light can cause damage to the retina. The American Macular Degeneration Foundation warns that retinal damage caused by blue light may lead to macular degeneration, which causes the loss of central vision — the ability to see what’s in front of you.
It should be noted however, that most studies show this effect with the light being held very close to the retina, which may not exactly replicate typical phone use.
