Babies Sleep Listening to Lullaby: Often, when babies don't sleep and start crying, it's recommended to lull them to sleep by singing a lullaby. Because listening to a lullaby makes a child feel safe.

Why do babies fall asleep listening to lullabies?
Babies Sleep Listening To Lullaby: For centuries, there has been a tradition in Indian society of singing lullabies to put children to sleep. On hearing a lullaby in the mother's slow and sweet voice, even a crying child calms down in a moment and falls into a deep sleep. After all, what is the connection between lullaby and sleep that a child falls asleep immediately after hearing a lullaby? A child crying loudly starts sleeping deeply with a lullaby. There is no big science behind this, in fact, the rhythm of a lullaby calms the heartbeat of the child, due to which the child starts sleeping.
lullaby feeling
From the time a baby is in the mother's womb, it listens to its mother's voice and her heartbeat. When a mother gently sings a lullaby while holding the baby close to her chest, the baby is reminded of that safe environment. The mother's soothing voice reminds the baby that it is completely safe. This feeling of security helps the baby sleep. Furthermore, when a baby is young, its nervous system is not fully developed. Therefore, when someone speaks loudly or shouts, the baby becomes frightened and starts crying.
According to science, when a baby listens to a lullaby or music sung in a monotonous rhythm, their heart rate and breathing rate slow down. The calming music of a lullaby relaxes the baby's body, allowing them to become drowsy and fall asleep.
Decreased stress hormones
When a child cries or becomes irritable, the stress hormone cortisol increases rapidly in their body. When they hear a parent's soothing voice, their mind immediately calms down. This releases happiness hormones like oxytocin and endorphins in the child's body. These hormones reduce pain and stress, allowing the child to fall asleep more easily. Furthermore, young children often cry due to loud noises around them or due to their own pain, such as a toothache or leg pain.
In such situations, when children listen to lullabies, their attention shifts from their discomfort and pain to the sweet sound of the lullaby. This is medically known as audio-visual distraction. When the child's attention is diverted, they forget their pain, close their eyes, and fall asleep.
