Stop. If you are buying a new iPhone, don t use
it in bed---and not just because nighttime smart-
phone use messes up your sleep cycle.
The blue light from personal electronic devices
has also been linked to serious physical and mental
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 mela-
tonin, which throws off your body s natural sleep
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 ten 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 expo-
sure 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
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
2. There may also be a link between cataracts and
blue light, though more research is needed. Gigaom
cited an eye doctor who says he s starting to see 35-
year-olds with eyes that are as cloudy with cataracts
Though a single account can t prove that blue light
exposure causes cataracts---this doctor just thinks
there s a link, which doesn t count as evidence---the
idea is being investigated. Still, studies haven t con-
cluded anything certain yet.
3. Exposure to blue light at night can ruin sleep.
Bright blue light disrupts the brain s production of
melatonin, a hormone that helps regulate the sleep
cycle. That s fine in the morning, but our brains are
supposed to start producing melatonin when we are
ready for sleep, and blue light interferes with that
process. That s why smartphones ruin sleep, and
messing with your sleep has a long list of associated
health consequences that range from obesity to genetic
disruption and memory problems.
4. Sleep disturbance and "light at night" have been
linked to higher cancer risk, particularly for breast
and prostate cancers. In addition to helping us sleep,
melatonin also functions as an antioxidant. And while
more research is needed, researchers have pointed
to "uninterrupted darkness" as potentially protective
against cancer. People whose natural melatonin pro-
duction is suppressed are at a higher risk for a variety
of cancers, though a causal relationship has not been
5. Blue light may also take a toll on mental health.
Research also shows that people whose melatonin
levels are suppressed and whose body clocks are
thrown off by light exposure are more prone to
Our weird relationship with blue light
Light tells us when to wake and when to sleep. When bright
blue light sends a signal to the brain to stop producing melatonin,
it also primes your brain to start production of the hormone
again later---in theory while you are getting ready for bed.
When nighttime screen usage convinces our brains that it s
morning and they shouldn t produce melatonin, that starts
to wreak havoc on our bodies. (Business Insider)

Exposure to blue light from personal electronic devices, at night can ruin
