Why do nightlights reassure children? Scientific explanations + practical advice
🌙 Why do nightlights reassure children?
Fear of the dark is a normal part of children's development, especially between the ages of 2 and 6. Their imagination becomes more vivid, their sense of orientation changes, and certain shadows or noises can become a source of anxiety.
To soothe these nighttime anxieties, many parents turn to nightlights. But why do they work so well? And how do you choose the right light to help your child fall asleep?
In this article, we explore the opinions of sleep specialists , as well as concrete tips for creating a soothing bedtime ritual .
🌟 Why are children afraid of the dark?
The fear of the dark appears at the time when the child is developing their imagination.
Experts explain that:
-
Children have difficulty distinguishing between imagination and reality.
-
Shadows sometimes take on disturbing shapes.
-
Total darkness eliminates reassuring visual cues.
➡️ A night light therefore offers a stable and reassuring point of light , helping the child to feel safe.
💡 How does a nightlight help a child sleep better?
A soft, warm light can:
✔ Reduce anxiety
It creates a constant visual reference point, soothing children prone to nighttime awakenings.
✔ Promotes sleep
Warm lights do not interfere with melatonin, unlike blue lights.
✔ Encourage autonomy
The child can get up or find their cuddly toy without stress.
🌈 Which nightlight colours are most suitable?
Recommended colors:

Amber, orange, soft red → soothing
-
Warm yellow → reassuring
To avoid:

Black or cold white , which can disrupt sleep.

The room should not be lit like daylight.

Fast-paced animations can overexcite the child.

A smooth transition helps the child gain confidence.
