Do
you often find yourself up late at night, basking in the cool glow of your
television or smartphone? If so, your sleep quality may be taking a hit.
Several
recent studies have shown that these devices actually steal sleep from kids and
adults alike. What makes this a problem is that more people than ever are using
electronics in the bedroom. Here’s a few stats demonstrating the pervasiveness
of the issue:
- The 2014 Sleep in America poll by the National Sleep Foundation estimates that 89% of adults and 75% of children have at least one electronic device in their bedrooms.
- Their 2011 poll found that in the hour before bed, up to 95% of adults regularly use tech and electronic devices.
- Younger people are more likely to use smartphones, laptops and play video games, while older adults are more likely to watch TV.
- Pew Research polls also found that two-thirds of adults take their smartphones to bed (that jumps up to 90% for 18 to 29 year-olds!).

on to learn why you should banish electronics from your bedroom and for tips on sleeping better
after your digital detox.
Five
Ways Electronics Affect Your Sleep and Health
Electronics
work on your physical body and on your mind, which can affect your sleep
schedules and contribute to sleep deprivation. Here are five of the most
important ways electronic devices like smartphones, computers and TV alter your
slumber.
1.
Blue Light Suppresses Melatonin
It
is well-established that light plays a powerful role in the regulation of our
internal circadian rhythms. Electronics like televisions, smartphones, tablets,
computers and even LED lights emit blue light, which is believed to be
particularly important when it comes to sleep.
Recent
research from Harvard and University of
Toronto researchers found that light in the blue spectrum acts on our
bodies by suppressing natural melatonin. Since melatonin is the hormone that
induces drowsiness, delaying its release means more time spent awake and
greater difficulty getting sleepy.
2.
Stimulation and Stress Keep Your Mind Awake
Active
and engaging electronics like tablets, laptops, smart phones, and televisions
stimulate your mind and distract you from sleeping. A recent Norwegian study correlated computer
and mobile phone use before bed in particular with increased insomnia.
But,
falling asleep is only part of the issue. In the 2011 NSF poll mentioned
earlier, 10% to 20% of younger adults admitted to waking up multiple times per
week due to disturbances from their phones and 26% admitted to texting or
emailing after initially going to sleep in the 2014 poll.
Waking
up to check your phone in the middle of sleep can affect deep sleep and make it
harder to get back to bed. And if checking those work emails or social media
accounts brings you stress, that can make it even more difficult to sleep.
3. Regularly Missing Sleep Sets the
Stage for Weight Gain
While
weight and obesity depend on several factors, sleep habits do appear to play a
role according to research from the past few years.
One childhood study recently published in the BMC
Public Health journal found overweight children slept less than normal
weight kids, which authors linked with chaos in the home as well as unchecked
screen time, TVs in bedrooms and other factors.
Another
Brigham Young University study found that
young women with inconsistent sleep schedules were more likely to have higher
body mass index ratings than consistent peers. A large scale study of nurses also found
that short sleep increased obesity risk over time.
It
is believed that consistent sleep deprivation acts on the body’s physical
metabolism and extra hours awake means extra hours to eat, both of which can
contribute to weight gain.
4.
Delayed Sleep and Wake Lag Can Affect Health and Productivity
An Australian survey of teenagers found that
greater use of electronics (including phones, computers and TV, but not radios)
was associated with greater delays to sleep/wake schedules and waking up later.
In
the 2014 NSF poll, children who had electronic devices on at night in their
rooms had the highest reports of fair to poor sleep, while those who left
electronics off had the highest reports of excellent sleep. Children who had
electronics on sometimes also had lower average sleep duration than kids whose
electronics were off or not in their bedrooms.
In
children, teens and adults alike, getting insufficient sleep is associated with
impaired cognition and learning, impaired memory, impaired decision making,
daytime fatigue and a wide range of health problems over time.
5.
Associating Your Bed with Other Activities Can Make Sleep Harder
Doing
non-sleep activities in bed like watching TV, playing games, working or
studying can be bad for sleep. Basically, the more things your brain associates
your bed with, the less it thinks of sleep when you are there.
Sleep hygiene experts recommend reserving the
bed for rest only to train your mind for better sleep. If you can’t sleep after
several minutes, it is better to get out of bed and do something like read or
listen to music until you feel sleepy.
Detaching
from Electronics and Sleeping Better
Here
are a few helpful strategies for weaning yourself or your kids off of
electronics in the hours before bed along with other recognized sleep hygiene
tips.
Institute
a digital detox in your home.
Set
an off limits time for televisions, computers, video games, tablets and cell
phones, and have everyone check their smaller devices in a central location if
needed.
Kill
the TV and dim lights two hours before bed.
In
the hours before bedtime, start reducing bright lights and turning off the
televisions. Consider swapping the bright lights in a couple of lamps for
reddish or orange-toned bulbs for better evening lighting. Harvard researchers
also suggest wearing blue light-blocking glasses for night owls and shift
workers.
Turn
phones to silent at night.
Make
sure everyone’s phones are set to silent at night to avoid disturbances,
especially if you feel like you must sleep with it nearby. If you are worried
about missing emergency phone calls, there are apps that will screen calls
during certain times or block certain notifications until morning so you can
get undisturbed rest.
Swap
electronics for other relaxation activities.
If
you are worried about being bored without your gadgets at night, there are
still many calming and
non-electronic things you can do to wind down. Read with dimmer light,
journal about your day, try yoga or meditation, chill out to favorite songs, or
find other ways to relax.
Tune
up your sleep hygiene and bedtime routine.
Healthy
sleep habits include sticking to regular bed and wake times, allowing for at
least seven hours of rest per night, getting regular sunlight and exercise
during the day, keeping rooms cool, and limiting stimulants. A normal
pre-bedtime routine can also help you get ready for sleep. A routine might
follow a pattern like: shower, get tomorrow’s outfit ready, sip some tea, read
a little, brush your teeth, stretch, and then hop into bed.
Reducing
electronics at night might take a little getting used to, but the benefits of
better sleep and a healthier body and mind are well worth it. Remember, all of
your e-mails, games and social media accounts will still be waiting for you in
the morning!
