So, what do you do in this debate?

The debate whether the bedroom lights should be turned off completely when children are asleep at night has no one-size-fits-all answer. It ultimately depends on your child’s comfort, age, and personal preferences.

In this article, we help you make informed and thoughtful choices for your child’s bedtime routine.

The Importance of Sleep Environment

Creating an ideal sleep environment for you and your child is crucial for the well-being of everyone in the house. Quality sleep is essential for physical and mental development, and the sleep environment plays a significant role in achieving this.

Creating an ideal sleep environment is a multifaceted task, one that involves careful consideration of various factors.

These are explained below:

1. Melatonin Production and Deep Sleep

The hormone melatonin plays a pivotal role in sleep environment and health. This hormone, also called the hormone of darkness, is the body’s natural sleep regulator, and its production is influenced by light and darkness.

The hormone secretion increases soon after the onset of darkness, peaks in the middle of the night, between 2 and 4 a.m., and gradually falls during the second half of the night. This circadian rhythm of secretion plays an important role in its hormonal activity. 


When exposed to darkness, the body increases melatonin production, signaling that it is time to rest. This leads to a deeper and more restful sleep, to ensure your child wakes up refreshed the next day.

2. Circadian Rhythms

A consistent sleep schedule is essential for children, as it helps establish and maintain healthy circadian rhythms. Circadian rhythms are the body’s internal clock, determining the sleep-wake cycle. It is a cyclical 24-hour period of human biological activity.

When properly aligned, a circadian rhythm can promote consistent and restorative sleep. But when this circadian rhythm is thrown off, it can create significant sleep problems, including insomnia.

Keeping the bedroom dark at night helps synchronize your child’s internal clock, ensuring that their body knows when it is time to sleep and when to wake up.

3. Minimizing External Disturbances

External disturbances, such as the glow of passing car lights, street lamps, or early morning sunlight, can significantly disrupt the bedroom environment, and your child’s sleep in particular. A dark bedroom minimizes these disturbances, by providing a tranquil and uninterrupted sleep environment.

Let us consider these key factors when deciding whether to keep the bedroom bright or dark.

The Pros of Complete Darkness in the Bedroom

  2. Healthy Circadian Rhythms: Complete darkness helps establish and maintain a healthy circadian rhythm, ensuring your child’s body knows when it’s time to sleep and wake.
  3. Minimal Disturbances: A dark room reduces the chances of external disturbances, such as passing car lights or street lamps, disrupting your child’s sleep.

The Cons of Complete Darkness in the Bedroom:

  1. Fear of the Dark: Some children may develop a fear of the dark, leading to bedtime resistance or night terrors.
  2. Inconvenience: If your child needs to use the bathroom during the night, complete darkness can be inconvenient and may increase the risk of accidents.

  3. Invest in Light-Blocking Curtains: To minimize external disturbances, invest in light-blocking curtains or blinds to keep the room as dark as possible.
  4. Create a Bedtime Routine: Establish a consistent bedtime routine to signal to your child that it’s time to sleep. This routine can include dimming the lights as part of the wind-down process.
  5. Open Communication: Talk to your child about their preferences and any fears they may have about the dark. Open communication can help address their concerns and ease bedtime anxiety.
