LED Night Light is the Best Night Light You Could Get
There is a big difference for people to sleep with or without their night lights on during the hours of night. This is especially true when it comes to youngsters who, at times get scared of the darkness afraid there is a monster hiding under their bed. Naturally, you feel like you’d want to protect your child(ren) from these nightly horrors which could turn a beautiful day into an evening nightmare. LED lights have been proven to provide children with a source of light to ward off these evils but not much is known or explained regarding to a person’s psychological responses regarding a night light during bedtime.

What Color Night Light is Best?
If you have to sleep with a night light on you might think that blue and white lights might create a calming sensation and help you sleep best. However, a new study involving hamsters done on August 6, 2013, at Ohio State University suggests that blue light had the worst effects on mood, followed closely by white light.
The hamsters exposed to red light at night had significantly less evidence of depressive-like symptoms and changes in the brain linked to depression, compared to those that experienced blue or white light. However, total darkness at bedtime is still best for sleep.
So why is the color red a better light for at night?
Specialized photosensitive cells are able to detect any light and send messages to a part of the brain that helps regulate the body’s circadian clock. This is the body’s master clock that helps determine when people feel sleepy and awake. These cells are most sensitive to blue wavelengths of light and least sensitive to red wavelengths.
In nearly every measure of this study, the hamsters exposed to blue light were the worst off, followed by those exposed to white light. While total darkness was best, red light along with dampened white light was not nearly as bad as the other wavelengths studied.
When you are looking for a midway of ensuring you, or your child suffers little to no side effects from having an LED night light to ensure the boo boos are away and you can get to sleep safely, a night light with red or dampened white color is best.
Is It OK to Sleep with A Night Light?
Our body’s basic rhythms, including our sleep/wake cycles, are tied to light exposure. Ordinarily, your body produces the soporific (sleep-inducing) hormone melatonin as a preparation for sleep. Melatonin suppression caused by light is at the heart of much of the research linking nighttime light to sleep disorders and poor health. The effect of even a brief amount of light is long-lasting. Bright light late in the evening — around midnight — can push your sleep/wake cycle back by half an hour or so, making you sleepy later in the evening the following night. On the other hand, bright light early in the morning, when you first wake up, advances your cycle, bringing on sleepiness earlier. For people whose light exposure and sleep habits are chaotic, the end result is a disordered sleep/wake cycle and related poor health outcomes.
