When it comes to nightlights, it sure is. Research shows that white, blue or green may inhibit the release of the sleep hormone melatonin. This hormone is released by the brain in response to light sensitivity in the eyes. The more exposure you and your children have to these wavelengths of light as you near bedtime may make it difficult to fall asleep and stay asleep. If you wake in the middle of the night, the wrong color nightlight can make it more difficult to fall asleep.
The right color?
According to multiple sources, the very best nightlight colors are red or orange. These colors are not usually seen in daylight wavelengths which are more blue/green and won’t falsely inform your brain that it’s time to wake up if your sleep in interrupted.
Avoid other blue light at night
If you or your children are exposed to the screens of your phone, tablet or computer the blue light emitted by these devices can have a detrimental effect on your ability to drift into slumber. Some studies show an even greater effect on teens and adolescents. There are many things you can do to avoid this effect: turn off screens an hour before going to bed, invest in some blue light blocking glasses or install an app that alters the screen color. Just dimming the brightness on your electronics can help reduce the sleep delay.
