In the evening, everything feels calm… until darkness falls. Then a familiar question appears for many parents: should we leave the night light on, or is it better to turn it off? On one hand, we want our child to feel safe. On the other, we worry about sleep quality and health. Let’s take a closer look at how light affects children’s sleep and how to find the right balance.

Why children want to sleep with a night light on

Fear of the dark is a natural stage of development, especially between the ages of 2 and 6. At this time, a child’s imagination becomes more active, and darkness can intensify feelings of anxiety. A gentle night light provides a sense of control and predictability, helping the child calm down and fall asleep more easily. This is not a whim, but a genuine need for security.

How light affects a child’s sleep

A child’s sleep, just like an adult’s, is regulated by the circadian rhythm. A key role is played by melatonin – the sleep hormone, which is released in darkness.
Too intense or cool-toned light:

• can make falling asleep more difficult
• may cause more frequent awakenings
• can result in lighter, less restorative sleep

However, this does not mean that all light is harmful.

Is sleeping with a night light on unhealthy?

No – as long as the light is appropriate. The issue is not the night light itself, but:

• excessive brightness
• a cool, white light colour
• improper placement (for example, shining directly into the child’s eyes)

Soft, warm night lighting does not disrupt sleep as much as many parents fear. For many children, it actually supports calm and peaceful falling asleep.

What kind of light is safe at night

If a child sleeps with a night light on, it’s worth paying attention to a few key points:

• warm light colour (yellow or amber tones)
• low intensity – the light should be a background glow, not room lighting
• no flickering or harsh points of light
• safe materials that do not heat up and are suitable for a child’s room

A well-chosen night light creates a soft, soothing atmosphere instead of overstimulating the child.

Where to place the night light so it doesn’t disturb sleep

Placement matters a lot. A night light:

• should not shine directly onto the child’s face
• works best near the bed or slightly to the side as an orientation light
• should gently illuminate the space, not the entire room

In Montessori-inspired rooms, low, subtle lighting that is accessible to the child but not intrusive is often preferred.

Should you gradually help your child stop using a night light?

If a night light helps your child feel safe, there is no need to force a change. Over time, many children naturally give up the light as their sense of security grows. You can:

• gradually reduce the brightness
• choose increasingly subtle lighting
• give the child a sense of choice and control

Gentle transitions are always better than sudden changes.

In the end, it’s worth remembering one thing: good sleep is not only about darkness, but above all about a sense of safety. If a soft night light helps your child fall asleep calmly, it is a support – not a problem. The key lies in moderation, warm light, and making conscious choices that truly serve the child and the whole family.
