Can Babies Sleep With Red Light?

    In this blog post, we’ll explore the advantages of using red light for babies’ sleep, the science behind it, and the factors to consider when making this choice.

    What color light is best for baby sleep?

    The best color light for baby sleep is no light at all, as complete darkness is ideal for promoting healthy sleep patterns. However, if you need to use a light for nighttime activities such as feedings or diaper changes, red light is the preferred option. Red light has the least impact on the circadian rhythm and melatonin production, which helps maintain a proper sleep-wake cycle for your baby.

    Do babies sleep better in dark or red light?

    Babies sleep better in complete darkness, as it helps regulate their sleep-wake cycle and promotes the production of melatonin, the sleep hormone. However, if a light is necessary for nighttime activities, red light is the better choice compared to other colors. Red light provides gentle illumination without overstimulating your baby’s developing eyes or interfering with their circadian rhythm.

    Is red light bad for babies’ eyes?

    Red light is not bad for babies’ eyes when used appropriately. It provides gentle illumination that is less likely to overstimulate their developing eyes compared to other light colors. However, it is essential to use a dimmable red light and position it away from the crib or bassinet to avoid direct exposure to your baby’s eyes. Always ensure that the intensity is kept low to create a calming and soothing atmosphere without causing any harm to your baby’s vision.

    The Science of Light and Sleep

    Our body’s internal clock, or circadian rhythm, is influenced by light exposure. Blue light, which is emitted by screens and electronics, can disrupt sleep patterns and suppress melatonin production, the hormone that helps regulate sleep. Red light, on the other hand, has the least impact on our circadian rhythm.

    Benefits of Red Light for Babies’ Sleep

    • Gentle Illumination: Red light provides soft illumination that won’t overstimulate your baby’s developing eyes. This makes it an excellent choice for night feedings and diaper changes without disturbing their sleep.
    • Promotes Melatonin Production: As mentioned earlier, red light does not interfere with melatonin production. This helps maintain a healthy sleep-wake cycle for your baby.
    • Sleep Environment: Red light can create a calming and soothing atmosphere in the nursery, helping your baby feel more comfortable and secure during bedtime.
    • Easier Transition to Sleep: With red light, your baby is less likely to be overstimulated before bedtime, making it easier for them to drift off to sleep.

    Factors to Consider When Using Red Light

    • Age: While red light is beneficial for babies, it’s essential to remember that newborns need complete darkness for optimal sleep. Only introduce a red light when your baby is a few months old and has developed a more stable sleep pattern.
    • Intensity: Opt for a dimmable red light to control the brightness. Too much red light can still be stimulating and interfere with your baby’s sleep.
    • Timing: Use the red light only when necessary, such as during nighttime feedings or diaper changes. Turn it off when not needed to ensure a dark sleep environment.
    • Positioning: Place the red light away from the crib or bassinet to prevent direct exposure to your baby’s eyes.


    Using a red light in your baby’s nursery can be a helpful tool in promoting a healthy sleep environment. The gentle illumination and minimal impact on the circadian rhythm make it a great option for parents seeking to minimize disruptions during nighttime feedings and diaper changes. However, it is important to introduce red light at the appropriate age, monitor its intensity, and use it only when necessary. By considering these factors, you can create a comforting and sleep-friendly atmosphere for your little one.
