The Color of Your Night Light Affects Mood

For young children still learning how to be independent, a night-light can come in handy. Not only
are night-lights useful for children, they are also useful for lighting hallways for midnight trips to
the bathroom or kitchen. Since night-lights are created with multiple designs and different colors,
people have a lot to choose from. According to a new study, researchers found that the color
of the night-light can play a huge factor in affecting people's moods.
"Our findings suggest that if we could use red light when appropriate for night-shift workers,
it may not have some of the negative effects on their health that white light does," Nelson said.
Furthermore, for young children, a red night-light might be the best option.The only group
of hamsters that exhibited normal moods and behaviors were not exposed to light at all and
moved around in the darkness. The researchers believe that these findings could potentially be
applied to humans. For people who work late nights and night shifts, the color of the lights
could affect their mood. For example, people who work the security desk at night and are
exposed to blue light could be at a higher risk of developing depression.
The study was published in the journal, Neuroscience.
