Will a newborn's lack of sleep affect their development?

Introduction
Newborns who do not sleep well may suffer from sleep deprivation, leading to circadian rhythm disturbances and interfering with the pituitary gland's secretion of growth hormone, thus affecting physical development. It can also impair the development of brain cells, neural pathways, and the cerebral cortex. If the sleeplessness is caused by conditions such as colic, respiratory infections, or rickets, it may further lead to decreased immunity.
Neonatal sleep deprivation may affect physical development, intellectual development, and may also lead to decreased immunity.
1. Impaired Physical Development
The cerebral cortex of newborns has relatively low excitability, and sufficient daily sleep is essential for physical and nervous system development. The pituitary gland in newborns secretes growth hormone continuously over 24 hours, promoting skeletal development and height growth. Lack of sleep in newborns can lead to insufficient sleep and circadian rhythm disruption, which often interferes with the pituitary's secretion of growth hormone, thereby negatively affecting physical development.
2. Impaired Intellectual Development
The nervous system of newborns is not yet fully mature and develops rapidly after birth. During sleep, cerebral blood flow increases, promoting greater synthesis of brain proteins and supporting intellectual development. If newborns do not sleep adequately, it may adversely affect the development of brain cells, neural structures, and the cerebral cortex.
3. Decreased Immunity
Newborns naturally have weak immune function. Sleep deprivation may be caused by underlying illnesses such as colic, respiratory infections, or rickets, which can further reduce immunity, impair mental state, and negatively impact overall health.
