New Research May Make You Wonder If Blue Light
May Be Good For Sleep After All
These days, it is customary for people to take
mobile devices into the bedroom when turning in.
They may check their social media, chat to
friends or even watch a movie or tv show on their
phone. The consensus is artificial light stops
you getting to sleep at night. It is felt the
blue glare keeps you awake. However, a study has
reportedly cast doubt on this assumption,
suggesting the issue may not lie with the shade
of the light, but the type.

According to researchers at Manchester
University, it might not be the blue of the light
disrupting your rest, but its warmth and
brightness. In the course of their experiments,
they showed a variety of light settings to
laboratory mice, to see how they
reacted. Although the study, which published its
results in the Current Biology journal, has not
been without criticism. It was designed to
explore the long-held belief artificial blue
light can affect a persons sleeping
pattern. So, researchers decided to expose their
mice/ guinea pigs to different colours, switching
from blue to yellow. They also altered the
brightness from a high to low register.
Scientists noticed that, when both the blue and
yellow were bright, the subjects were stimulated,
instead of feeling restful. Just as they had
anticipated. However, when researchers turned
the brightness down, the mice were more restful
under blue light, compared to yellow, which they
claim truly reflects what happens in nature.
During the day, the light is comparatively white
or yellow coloured, which is better for staying
awake. However, when the sun goes down, it
becomes increasingly blue, going on dark, which,
going by the findings, is more conducive for
sleep. But, ironically enough, devices like
laptops and mobile phones are fitted with
night-mode settings to diminish blue light, to
negate sleep disruption. Although, the
researchers conducting the survey claim this may
have the opposite effect than intended.

The findings of the research may be debatable in
some circles, but they do pose an interesting
question, which may make people look at the
notion of mobile screens affecting sleep patterns
in a different light. Source https//www.bbc.co.
