Sleep is essential for newborns as it is crucial for their development and growth. Darkness is important for restorative sleep for babies, children, and adults. Light exposure is the only thing telling newborns the difference between day and night, considering they were in total darkness for nine months in the womb. While newborns can sleep in both light and dark rooms, darkness and the use of a white noise machine can be beneficial.

What You'll Learn
Newborns can sleep in the dark, but they don't have to
Newborns can sleep in light or dark rooms, but creating a distinction between day and night may help them develop a consistent sleep-wake cycle.
Newborns can sleep in the dark, and many sources suggest that they sleep better in darker rooms. Darkness helps to prevent stimulation that could disrupt their sleep and encourages their bodies to produce melatonin, a hormone that helps them sleep. However, newborns can also sleep in light rooms, and some parents prefer to let their newborns nap during the day in a light room to help establish their circadian rhythm.
When babies are first born, their circadian rhythm is still developing, which means they do not yet have a consistent sleep-wake cycle, and their bodies need help determining whether it is time to sleep or be awake. They will typically sleep for short periods throughout the day and night. To help them develop a healthy sleep-wake cycle, parents can establish a routine by keeping the room bright during the day and dark at night. This distinction between light and dark will help set their biological clock to waking and sleeping at the same times each day.
However, newborns do not have to sleep in the dark. Some newborns may sleep better in light rooms, and parents can experiment with different lighting conditions to find what works best for their baby. For example, if a baby is experiencing day and night confusion, parents can try adding more light during the day and keeping the room dark at night to help regulate their circadian rhythm.
Ultimately, the decision of whether to have a newborn sleep in a light or dark room depends on the baby's preferences and the family's needs. Some newborns may be more sensitive to light than others, and parents may need to try different lighting conditions to find what works best for their baby.

Light and dark play a role in baby sleep
Light and dark play a significant role in baby sleep. When babies are first born, their circadian rhythm is still developing, and their bodies need help determining whether it is time to sleep or be awake. Newborns typically sleep for short periods throughout the day and night, and this can range from 30 minutes to 4 hours at a time, which is healthy and normal.
During the day, it is recommended to let your newborn nap in a light room to help establish their circadian rhythm. If your baby sleeps all day in the dark, they may confuse their days and nights, waking up frequently at night. However, if your baby is dealing with day/night confusion, you can try naps in a dark room. Darkness helps to signal to their bodies that it is time to sleep and prevents stimulation that could disrupt their sleep.
At night, it is beneficial to keep the room as dark as possible. Darkness promotes the release of the sleep hormone melatonin, which is crucial to your baby settling and sleeping well. Exposure to light, especially blue light, can stimulate babies, making it harder for them to fall asleep or stay asleep. Light suppresses melatonin production and disrupts the circadian rhythm. Even small amounts of light, such as a night light, can impact sleep quality.
It is important to note that babies do not develop a fear of the dark until they are older, typically around two years old. Therefore, night lights are not necessary and can be introduced later if the child expresses a fear of the dark.

Babies find the dark comforting
Darkness is essential for restorative sleep, for babies, children, and adults. When we sleep, our bodies go through different stages of sleep, including light sleep, deep sleep, and REM sleep. These stages are important for the body to repair itself, consolidate memories, and process emotions.
Babies do not need night lights, as any light will be stimulating for them and can prevent them from falling asleep or staying asleep. Light suppresses the production of melatonin, and disrupts the circadian rhythm. Even small amounts of light, such as the light from a night light, can have an impact on sleep quality. When melatonin levels are low, it's harder for babies to fall asleep and stay asleep.
However, there are times when a night light in the nursery or the room that you share with your baby can be helpful. Night lights can be a great tool for night feedings, diaper changes, or other nighttime activities. If you choose to use a night light, consider a night light that has a very dim setting and the option to change the light color. There is no need to introduce a night light into your baby or toddler’s room before they ask for it.
Babies sleep better in the dark. During the day, it is recommended to let your newborn nap out in the open in a light room to help establish their circadian rhythm. If you let your baby sleep all day in the dark, they may wake up frequently at night, thinking it's time to play. Newborns need a lot of sleep, usually between 14 and 17 hours a day. At night, it is beneficial to keep the room as dark as possible, and this is where swaddling, as well as keeping it quiet and unstimulating, is recommended. The darkness helps to signal to their bodies that it is time to sleep, helps to prevent stimulation that could disrupt their sleep, and encourages their bodies to produce melatonin, which is a hormone that regulates sleep.

Day/night confusion can be fixed by regulating their circadian rhythm
Newborns can sleep in the dark, and in fact, darkness is essential for restorative sleep for babies, children, and adults. When babies are first born, their circadian rhythm is still developing, and their bodies need help determining whether it is time to sleep or be awake. They will typically sleep for short periods throughout the day and night.
The circadian rhythm is the body's internal clock that plays a role in regulating bodily functions, not just sleep. It is the pattern your body follows based on a 24-hour day, and it is reset and restarts every morning when the first light hits the retina. It is guided by your brain, but outside factors, like light, can affect the rhythm too. For example, when light enters your eye, cells send a message to your brain that it can stop producing melatonin (a hormone that helps you sleep).
To help your newborn regulate their circadian rhythm, you can:
- Expose them to plenty of daylight and normal everyday activities. This will help them develop melatonin production and, consequently, a circadian rhythm more quickly.
- Keep a regular morning routine, as well as a regular evening routine. This includes predictable activities, such as regular meal times or patterns of activities in the day.
- Ensure the room is dark at night. Darkness helps to signal to their bodies that it is time to sleep, and it prevents stimulation that could disrupt their sleep.
- Keep the room light during the day. This will help establish their circadian rhythm and prevent them from getting their days and nights confused.
By regulating their circadian rhythm, your newborn's body will be able to operate on a healthy wake-sleep cycle.

Night lights can be useful for night-time activities
While darkness is generally recommended for newborn sleep, there are times when a night light in the nursery or the room can be beneficial. Night lights can be a great tool for parents during night-time activities such as night feedings and diaper changes. They can provide just enough illumination to navigate these tasks without fully waking the baby or disrupting their sleep.
The use of night lights should be minimal and as needed, as light exposure can impact a baby's sleep quality. Even small amounts of light can stimulate a baby's brain and make it harder for them to fall asleep or stay asleep. This is because light suppresses the production of melatonin, the sleep hormone, and disrupts their circadian rhythm. Introducing a night light with a very dim setting and the option to change the light colour can be a good compromise. Red light, in particular, is known to have a soothing effect and can be less stimulating for babies.
For newborns, it is recommended to keep days light and nights dark to establish a healthy sleep-wake cycle. During the day, letting your newborn nap in a light room with some noise can help set their internal body clock. However, keeping the room dark at night is crucial, as it signals to their bodies that it is time to sleep and promotes the production of melatonin.
As babies grow older, their sleep patterns and needs may change. Some babies may develop a fear of the dark around the age of two or older, and this could be an appropriate time to introduce a night light if they request it. Additionally, if your baby starts sleeping through the night and napping well, you can gradually introduce light into the room to see if they continue to nap well. However, if short naps or early mornings become an issue, reverting to a dark room may be necessary.

Frequently asked questions
Yes, newborns can sleep in the dark. In fact, darkness is essential for restorative sleep for babies, children, and adults. Light can disrupt the stages of sleep, leading to less restorative sleep. Darkness helps to prevent stimulation that could disrupt their sleep and encourages their bodies to produce melatonin, a hormone that helps them sleep.
While newborns can sleep in the dark, they do not need complete darkness to sleep. Newborns do not care much about where they sleep, so light won't bother them. However, as they grow older, they become more aware of their surroundings, and light can become a source of stimulation and distraction, making it harder for them to fall asleep or stay asleep.
It is recommended to keep the days light and the nights dark for newborns. During the day, let your newborn nap out in the open in a light room to help establish their circadian rhythm. Darkness during the day can confuse their sleep-wake cycle, leading to frequent waking at night.
There is no need to introduce a night light into your baby's room before they ask for it. Usually, babies are not afraid of the dark until they are around two years old, as their imagination does not develop until then. If your toddler expresses fear of the dark, you can introduce a night light with a dim setting and a red light option.
To improve your newborn's sleep, focus on creating a consistent sleep routine. This means having set wake-up and bedtime schedules. Additionally, ensure their room is dark, quiet, and free from distractions. You can also try using white noise or soft music to soothe your baby and block out sudden noises.
