Do Light Projectors Help Babies Sleep? 

The answer can be yes or no, depending on the color of the light. While blue lights are terrible for the eyes, other choices can act as a soother.

Many of these projectors use a short wavelength of light that looks blue to human eyes. Such lights substantially impact circadian and melatonin rhythm more than longer-wavelength light. 

Moreover, our retinal neurons react most intensely to blue lights and signal our brain to remain alert even though the beam is weak. 

So, are projectors good for babies? These projectors may be harmful to your baby’s eyes if you use blue lights. If the color is different, they can positively influence your child. 

The three benefits of using these projectors are: 

Sleep pattern

Many parents are reluctant to keep their kids in the dark. On the other hand, a newborn doesn’t need a lot of light to fall asleep.

As you may notice, babies don’t sleep much during the daytime because the bright sunlight annoys their rest. 

In this case, dim lights in the bedroom can assist your children’s sleep. As long as the illumination is not too distracting or too bright, they will love it. 


Your baby may suffer from nighttime anxiety. A kid can develop a fear of the darkness for multiple reasons. Hence, a baby sleep soother projector can calm babies as they sleep.

The protectors can also help with your comfort. A baby’s room is likely to have toys thrown about. Stepping in the dark increases your chances of stumbling or stepping on something.

The illumination of night lights allows you to see your surroundings better and keeps accidents from happening.


It’s okay to let your baby sleep in the darkness. However, what if you want to check on him during the right? 

Often, parents turn on the lights to see things clearly. Unfortunately, the bright beams will interrupt your baby’s sleep. It’s much more challenging to put him to sleep again. 

If you set a dim light in your child’s room, you won’t need extra lighting. You can even feed him with that light on.

Do Babies Sleep Better With Light?

In most cases, babies do not require lighting while sleeping. They’re far too young to be afraid of the dark because they have spent their first months in the dark womb. 

However, infants are different. Certain hues of beams appeal to some babies, and they sleep much better in dim lighting.

Toddlers may start to hate the dark. The illumination may be soothing and calming in this scenario.

Only one fact nearly works for all: Infants do not sleep well in bright lights. Intense illumination stops your baby’s body from producing melatonin, a hormone that helps people fall asleep.

Which Color Night Light Is Best For Babies? 

Artificial lights may affect your child’s rest in many ways, but not all sorts of illumination have the same effect. 

The wavelength of the red-based beam is significantly longer than that of other hues. According to research, red lights have no impact on the melatonin process’s internal body clock.

Although red beams don’t improve your child’s sleep dramatically, they don’t restrict melatonin production like the blue ones. 

Moreover, this color is not too exciting for your child and provides sufficient visibility for night meals and diaper changes.

Tips For Using Night Light Projector 

The light projectors can be good or bad for your baby, depending on how you use them. Here are some tips that bring out the best of those lights. 


Movable lights, such as blue or white lights, may disrupt melatonin production, making it hard for your child to fall asleep. 

You should select a night light that produces red beams or utilizes only a dim glow. It’s less likely to disturb and irritate your baby.

Different hue options are available on some projectors. They will be more helpful than one that only emits red beams during a light display. 

White noise 

No one can deny the wonderful effect of white noise on sleep. However, you’ll need to find a unit that either produces white noise with only red lights on or one that allows you to switch off the display while leaving the noise on. 

Light show 

Light shows are enjoyable for your infant and might make them quiet. You can use them as a tool for entertainment as well. 

However, watching the lights flashing and moving across the ceiling can be too exciting for kids, making them more awake and less sleepy. 

If you wish to install a projector, go for one with a slow-rotating still display. The image moves slowly as the lights stay in place, and the various hues don’t flash or move.
