Is the night light harmful to your child?

There are some persistent rumors that the night light is harmful to children. Their development could be disturbed and the light is even suspected of promoting myopia. This is accompanied by major concerns if you want to use a night light for children in the room.

But is there something to the rumors and is the night light actually harmful to children?

Here you can find out how safe the little slumber lights are and how they affect sleep.

Why do you actually want to use the night light on your child and is it even needed?

There are several reasons for using a light during the night.

If your child is anxious and has just moved into the nursery, the environment looks completely new. It still has to find its way around this new environment. However, during the night the darkness is a threat. Your child cannot see the room and the darkness increases the feeling of threat.

Every shadow and little noise can startle the child . It cannot process these impressions properly yet and the shadow quickly becomes a dangerous ghost.

That there are no ghosts in the room can be quickly proven with a night light. Because this gives just enough light that the room is lit up a little. So your child can see that there are no dangers lurking and fall asleep relaxed.

With the night light you can donate a little security and a feeling of security is conveyed.

Furthermore, the light is an important aid if your child has to go to the toilet at night or if they still go to their parents’ bedroom. It can orient itself better in the room and does not trip over the toys or other objects in the room. A night light with a motion detector only switches on when your child actually moves out of bed. This is a good compromise if you don’t want to keep the lights on all night.

The night light is therefore an important means of promoting sleep. Unlike other light sources, the body’s melatonin production is not inhibited. This is based on the composition of the light colors in night light.

There are other tips you can follow to promote sleep.

Before going to sleep, ventilate the children’s room and keep an eye on the temperature
Use sleep rituals like reading a story to the child
Darken the room
Reduce the volume

With these measures you create the best conditions so that your child feels comfortable in the room and can sleep deeply.


The question of whether night lights are harmful is easy to answer. The use of the night light does not cause any damage and this has been proven in several studies .

The rumor that night lights would cause myopia is based on a published study from 1999 .

In this study, a link was established between ambient light during the night and the occurrence of myopia. According to this, the night light would lead to a higher risk of myopia in children under the age of 2 years .

Since myopia is also a risk factor for other eye diseases and even blindness in adulthood, this should not be taken lightly at first.

more recent study from 2000 looked directly at myopia and night light. To this end, more than 1,200 children were examined. A connection between the brightness of the children’s room and the occurrence of myopia could not be established. Accordingly, it does not matter whether the room is completely dark, only illuminated with a night light or completely bright. Rather, a connection can be observed between the visual properties of the parents and the children.

Further scientific research confirms these impressions. The night light is not a risk factor for children when it comes to myopia.


So the night light does not favor myopia. However, does electrosmog pose a risk and could it affect sleep?

When using electronic devices, a magnetic field is generated. Harmful properties are ascribed to this field. In science, however, the harmfulness of electrosmog is controversial.

The WHO states that low-frequency electrical fields stimulate the nerves and muscles, but a health hazard has not been confirmed.

However, other public institutes warn more clearly about the dangers of electrosmog. These can damage the nervous system or affect the hormonal balance.

Let’s assume that you don’t want to expose your child to electrosmog – how dangerous are night lights in this context?

With night lights in the socket there is actually a small amount of electrosmog. A very weak magnetic field is built up. But this is negligibly small. In addition, the night light is not placed directly on the bed, but plugged in a little further. This means that your child does not even come into contact with the magnetic field.

If you want to be on the safe side, place the night light a little further from the bed. Then there is no danger.

If the night light is operated with a battery, there are no magnetic fields whatsoever. This means that your child is not exposed to electrosmog. So you can do thatLeave the night light in the shape of a turtle in your child’s bed with a clear conscience.


For your personal perception, it may hardly make a difference whether the light is bluish or reddish. Perhaps you have preferences here and you like one warmth of light better than the other, but superficially you won’t notice any difference.

However, it looks different for your body. This perceives bluish light differently. The blue light keeps your body awake. Melaton production is inhibited by the blue light components As a result, the body is not put into “sleep mode”, but remains on alert.

The blue light occurs, for example, on smartphones or other screens. Therefore, you should not use your smartphone before going to bed.

Reddish light, on the other hand, promotes falling asleep. The sunset may be conveyed to the body through this and the sleep hormone is thus increasingly produced. This fact is used with alarm clocks that simulate daylight .

The night light shines only weakly, so that the light color has hardly any influence. But if you want to be on the safe side, use a night light that glows reddish.


So that the night light promotes sleep and does not disturb you, you should pay attention to the following information.


The night light should only be so bright that the room no longer appears pitch dark. For a restful sleep, however, it is advantageous if the room is not too bright. As a rule of thumb, a light intensity of 10 lumens should be measured at a distance of one meter. Most night lights are designed so that they don’t shine too brightly. However, you should avoid using other LED lamps as night lights, as they will be too bright.


It is of course an advantage if the night light does not stay on all night. Because when your child sleeps, they no longer need the light.

You can therefore use night lights with sensors that , for example, react to movements and only switch on when your child moves. Or you take alternatives that use a timer and switch themselves off after a certain period of time. This saves you some electricity and the light does not shine all night.


Even if the night light is not a highly complex device, the current standards should be adhered to. Make sure that the products have the GS or TÜV seal. This ensures security.

With battery operated lights, the battery compartment must be securely closed. If the compartment is damaged, replace the entire device to be on the safe side.


The use of the night light is completely harmless for your children. There are no health risks and following the tips will promote sleep.

Thus, the night light is a sensible investment if your child is still afraid in the dark and their own room seems a bit scary. Thanks to the light, your child will no longer go to their parents’ bedroom, but will want to spend the night in their own room.

Hello, I’m Jamie Clark, 32 years old, and I have been living in the USA for a few years.
Since I was a child, I have suffered from a house dust allergy, severely affecting me. I felt the effects both while exercising and while sleeping. Constant sneezing after getting up and difficult breathing were the consequences. The allergy has also developed into asthma, which is still a sporting restriction today.
