Why Newborns Love White Noise: The Science Behind the Soothing Sounds

White noise has long been known to help people fall asleep and stay slumbering, but did you know it can do the same for newborn babies? It turns out that babies, especially newborns, have a strong affinity for this type of sound. But why do newborns like white noise?

The answer lies in their womb experience. Before a baby is born, they spend nine months in the womb of their mother, which is a loud and constant environment. The sound of the mother's blood flow, heartbeats, and various other bodily functions create an ambient noise known as in utero sounds. These in utero sounds can be as loud as 80-90 decibels, which is similar to the volume of a vacuum cleaner or a busy restaurant.

When a baby is born, they enter a world that is relatively quiet compared to the womb. This sudden change can be a bit unsettling for them, making it harder for infants to sleep. White noise can provide a sense of comfort and familiarity as it closely mimics the loud, consistent sounds they've become accustomed to in the womb.

Another reason newborns favor white noise is that it helps block out other abrupt and startling noises. Unlike adults, newborns have yet to develop a sleep pattern and cycles are lighter and more frequent. White noise serves as a consistent backdrop, reducing the impact of sudden sounds that may otherwise wake a little one from their slumber.

For parents and caregivers, using white noise can be a helpful tool to soothe and settle a newborn baby. Devices such as white noise machines, apps, or even the sound of a fan or air conditioner can help your baby fall asleep faster and stay asleep longer. Remember, though, that it's recommended to keep the white noise at a safe volume level, around 50-60 decibels, and not too close to the baby's crib.

In conclusion, newborns like white noise because it provides comfort and familiarity, mimicking the sounds they experienced in the womb. Additionally, white noise can help drown out sudden, external sounds that can rouse a baby from their sleep. Incorporating a white noise machine or app can aid both newborns and their parents in achieving more restful sleep.
