Some of the symptoms
associated with smartphone use includes eye strain and headaches. However,
another concern associated with smartphone use is the negative effect posed to
eye health by blue light rays. We are all aware of the importance of sleep on
eye health. Not only does sleep improve our health from an emotional, mental
and physical point of view, but a good night's sleep can also contribute to a
properly working visual system.
This is due to the fact
that when we don't get a quality night's sleep our eye health suffers. But did
you know that there is actually a connection between our exposure to blue light
rays at a particular time of the day that can disrupt our body's normal
circadian rhythm? What is the body's circadian rhythm? According to the
national sleep foundation the circadian rhythm refers to a 24 hour internal
clock that basically controls your normal sleep cycle. It includes periods of
the day between sleepiness and alertness at regular intervals. In other words
it's like an internal clock that tells us when to get up and when to retire to
bed and it determines our sleeping patterns. For example, some people at
certain periods of time during the day, for instance, in the morning between 4
am and 6 am experience cycles associated with low energy. These low energy
levels often carry into the afternoon periods whereby people feel like taking
an afternoon nap between 2.30 and 3.30 pm. Then, there is a high energy peak
after this period that extends to about 6 pm. This can differ depending on your
daily schedule as some people are night owls while others are morning people.
Why is maintaining a
good circadian rhythm so important? This is due to the fact that this 24 hour
clock determines sleep and wake patterns. It also controls bodily functions and
hormonal levels in the body. If our circadian rhythm is disrupted this can lead
to problems like sleep disorders such as insomnia and this can also cause
problems with our eye health. For example, lack of sleep can cause dry eyes and
a deficiency in moisture in the eyes can also lead to eye problems related to
light sensitivity, blurry vision, redness and eye fatigue.
Did you know that using
your smartphone before going to sleep can actually disrupt your body's normal
circadian rhythm? Actually, this is due to the fact that smartphones emit blue
light rays that affects the cells in our eyes in such a way that it
communicates to the brain that it is time to wake up. As a result, this signals
an alertness response in the brain that can actually lead to sleep deprivation
thereby causing you to stay up late at night.
Additionally, sleep
experts discourage the use of smartphones before going to bed also due to the
fact that the blue light emitted from such devices decreases the body's natural
production of the sleep hormone called melatonin. This is an essential hormone
that helps us to get a good night's sleep. It also encourages healthy sleep
patterns and helps us to maintain a normal circadian rhythm.
So, what is the
solution to this problem? Well, if you find it very difficult to avoid using
your smartphone before going to bed try wearing special glasses that filter
harmful blue light while accessing such devices. Studies have shown that people
who wore special glasses such as orange tinted glasses that filter blue light
were still able to maintain a healthy circadian rhythm and still had healthy
levels of the sleep hormone melatonin in their system.
