Every living creature needs to sleep. It presents primary activity of the brain during early development of any organism. Sleep deprivation may have a great negative effect at any age and good night sleep is of critical importance especially during childhood. Also, certain cognitive functions of the brain may not be working effectively as they should if there is not enough sleep in this critical period of development.


Many studies came to results which say that irregular bedtimes at the age from 0 to 3 years old will have a negative effect on math skills, reading skills and spatial awareness. We may say that sleep is of the same importance as food, regarding its role in developing and proper functioning of the brain in future.

Sleep effect on brain development

Good sleep increases development of brain circuits known as synapses and also brain tissue. First, three years of life are most crucial for these brain changes. In fact, this is one of the main reasons that children recover much faster from head traumas than adults. This strong relationship between brain development and sleeping is called neuroplasticity.

Sleep effects on health

We all know poor sleep is connected to diabetes, heart disease risks, and high obesity, especially among children. Children with enough sleep have lower vascular damage risks. Also, some sleeping disorders within the children bring problems like elevated cortisol and glucose levels. Numerous everyday research studies warn people about this neglected and quiet, dangerous situation.

Sleep effects on learning capability

Those baby twitching seen within newborns is testing of the nervous system about connections between the brain and muscles. The brain of an infant is very busy throughout the night.


Many study types of research say that newborns are usually learning in their sleep and that kids with more amount of naps remember more.

Sleep affects growth

Most effective secretion of the growth hormone happens during deep sleep. Outnumbering studies show and confirm a relationship between deficient levels of the growth hormone and poor sleep.

So, according to above facts, it is of primary importance that internal clock of the children synchronizes with uninterrupted and sufficient sleep. There are many other reasons to take care of this like for example weight loss, reducing injury risks, increasing alertness which should make any parent understand child’s sleeping needs more seriously.

Helping your child get enough sleep

Checking on your little children with monitor may help you determine any issues child is going through while sleeping. With older kids, it is important to talk about their sleeping experience to solve any existing problem.  Regular sleeping routine, bedtime reading and creating good sleep environment should help them stay asleep.
