Sleep is essential for newborns, who need between 14 and 17 hours a day. Light and darkness play a huge role in baby sleep. Blue light, which is emitted by electronic devices, can be harmful to newborns and can even destroy retina cells and lead to loss of eyesight. It also suppresses the production of melatonin, a sleep-inducing hormone, and disrupts the circadian rhythm. Therefore, it is beneficial to keep the room dark at night to promote healthy sleep patterns. However, there are times when a night light can be helpful for activities like night feedings and diaper changes. If you choose to use a night light, consider a dim red light, which doesn't block melatonin production.
How to sleep light with a newborn
| Characteristics | Values |
|---|---|
| Light | Should be avoided before bedtime as it can reduce melatonin production and disrupt sleep. Blue light, in particular, is the most disruptive and is emitted by electronic devices. |
| Darkness | Encourages melatonin production and helps regulate sleep. It is recommended to keep the room dark during bedtime and let natural light in during the day to develop the baby's circadian rhythm. |
| Night Lights | Not necessary for baby sleep but can be helpful for night feedings, diaper changes, or other nighttime activities. Red lights are recommended as they do not block melatonin production. |
| Noise | Background noise can help some children sleep, while others prefer a quiet environment. Consistent noise levels can help maintain sleep. White noise or a fan can create a neutral sound to block out other noises. |
| Routine | A consistent bedtime routine can help babies fall asleep and self-soothe if they wake up. |

What You'll Learn
Blue light is harmful to newborns and can disrupt sleep
Newborns need a lot of sleep, usually between 14 and 17 hours a day. It is beneficial to keep the room as dark as possible at night, as darkness helps to signal to their bodies that it is time to sleep. It also helps to prevent stimulation that could disrupt their sleep and encourages the production of melatonin, a hormone that helps regulate sleep.
Blue light, which is emitted by electronic devices such as televisions, computers, and mobile phones, can be harmful to newborns and disruptive to sleep. Blue light stimulates the brain, making it harder for newborns to fall asleep and stay asleep. It suppresses the production of melatonin, which is essential for restorative sleep. Exposure to blue light can lead to inconsistent waking and sleeping patterns, as the brain associates blue light with noon and finds it challenging to settle into a deep sleep.
Additionally, blue light has been found to have negative effects on eye health. According to a study by the Scheie Eye Institute in Pennsylvania, children who sleep with the lights turned on are more likely to experience eyesight issues. Another study by Integrative Biology found that retinal cells exposed to high-intensity blue light exhibited cellular alterations and death.
To promote healthy sleep patterns for newborns, it is recommended to avoid blue light exposure for at least two hours before bedtime. This includes minimizing the use of electronic devices and ensuring that the sleeping environment is dark and free from light sources, such as night lights or streetlights filtering through windows.
While complete darkness can be beneficial for sleep, it is important to gradually introduce newborns to dim lights. Initially, they might find it frightening due to their underdeveloped eyesight. However, as they grow older, they can become accustomed to sleeping in darker environments, which may promote better sleep quality and independence during bedtime routines.

Darkness helps babies sleep better and deeper
Darkness plays a crucial role in helping babies sleep better and deeper. Light, especially blue light, can stimulate babies, making it difficult for them to fall asleep or stay asleep. Blue light is emitted by electronic devices such as televisions, computers, and mobile phones, and it can negatively impact a newborn's retina cells and lead to potential eyesight issues in the long term.
When exposed to light, the body suppresses the production of melatonin, a hormone that helps regulate sleep. This disruption to the body's natural melatonin production can make it harder for babies to fall asleep and stay asleep. Even a small amount of light, such as a night light, can impact sleep quality. Darkness, on the other hand, helps to signal to a baby's body that it is time to sleep and encourages the production of melatonin.
To create an ideal sleep environment for your baby, it is recommended to keep the room as dark as possible. This can be achieved through the use of room-darkening curtains or blackout curtains to block out any outside light. Additionally, light blockers for underneath doors can prevent light from creeping in. During the day, it is beneficial to let your newborn nap in a light room to help establish their circadian rhythm. However, as they grow and their circadian rhythm develops, longer periods of sleep at night and more regular nap times during the day will occur.
While some parents may worry about their baby being afraid of the dark, these fears typically do not develop until the age of two or older. It is also important to note that every baby is different, and it is always best to follow their unique routine for sleeping patterns and naps.

Night lights can be useful for night-time activities but aren't necessary
Night lights can be useful for parents during night-time activities such as feedings and diaper changes. However, they are not necessary for the baby, and it is beneficial to keep the room as dark as possible at night.
Babies sleep better in the dark as darkness helps to signal to their bodies that it is time to sleep. It also prevents stimulation that could disrupt their sleep and encourages the production of melatonin, which is a hormone that helps regulate sleep. Without melatonin, babies will have a hard time falling asleep and staying asleep.
It is important to note that light, especially blue light, can disrupt sleep patterns and brain development. Blue light is found in electronic devices such as televisions, computers, and mobile phones, and it can delay sleepiness and suppress melatonin production. Therefore, it is recommended to avoid electronics for at least an hour before bedtime and to keep the room dark during sleep.
If you choose to use a night light, consider a very dim setting with a red light option, as red light has a lower colour temperature and does not block melatonin production. It is also recommended to wait until your child is at least two years old before introducing a night light, and only if they are afraid of the dark.
To ensure a good night's sleep for your newborn, create a consistent routine and a quiet, dark environment. You can use room-darkening blinds or heavy curtains to block out light and noise. Remember, every baby is different, and it is important to follow their own sleeping patterns and routines.

Consistent noise and light levels can help babies sleep better
Keeping consistent noise and light levels can help babies sleep better. Light and darkness play a crucial role in baby sleep. While light stimulation is important for newborns to aid brain development, it can also be harmful. Blue light, for example, can stimulate the brain and delay sleepiness, suppressing melatonin production and affecting circadian rhythms. Melatonin is a sleep-inducing hormone, and darkness helps to encourage its production.
Babies sleep better in the dark, and it is beneficial to keep the room as dark as possible at night. This helps to prevent stimulation that could disrupt their sleep and encourages deeper sleep. However, during the day, it is recommended to let newborns nap in a light room to help establish their circadian rhythm.
Noise can also impact a baby's sleep. Some babies can settle for sleep and stay asleep with a little background noise, while others prefer a quiet environment. Keeping noise levels consistent can help your baby go to sleep and stay asleep. A fan, radio, or white noise machine can create a neutral sound that masks other noises and helps your baby sleep through sudden sounds.

A consistent sleep routine can help babies settle themselves
To help establish their circadian rhythm, it is recommended to let newborns nap during the day in a light room with noise. At night, it is beneficial to keep the room dark as darkness helps signal to their bodies that it is time to sleep, prevents stimulation that could disrupt their sleep, and encourages the production of melatonin, a hormone that regulates sleep.
As your baby grows, you can start to emphasise the difference between night and day. From 3-4 months, babies start to have their longest sleep at night, and you can begin putting them to bed drowsy but awake, which helps them learn to associate falling asleep with being in bed alone. This can aid in self-soothing, leading to longer and more restful sleep.
It is important to be consistent with your baby's sleep routine, and over time, they will learn to settle themselves and sleep through the night.
