Recent studies have revealed that sleep is not merely a time for rest, but it also plays a crucial role in physical development and critical stages of growth, especially in children.
The American Academy of Pediatrics conducted a survey and found that during sleep, the rate of brain development in children doubled compared to when they were awake. Additionally, the growth hormone in their bodies was secreted at three times the normal rate. This indicates that a deep and sufficient sleep will result in abundant energy and improved cognitive abilities for children.
However, there are some unique sleeping habits in children that many parents may not notice, but they can actually indicate a high IQ. Here are three notable signs:
Smiling during sleep
Many parents have likely witnessed their children smiling in their sleep. Usually, this is attributed to pleasant dreams. However, what it also reflects is a high IQ and EQ in children.
Smiling during sleep is not just an indication of happiness, but it also showcases a deep connection between the brain and the nervous system. Smiling is directly related to the nerves, while the brain controls the entire process. In fact, the nervous system of newborns is not yet fully developed, so for infants under six months, the display of emotions is often limited.
The smile of a sleeping child can indicate a high IQ and EQ.
Since pre-verbal children cannot express themselves verbally, their facial expressions become the only way to convey their emotions. Smiling during sleep in intelligent children with high emotional intelligence indicates the harmonious functioning of their neural network. It showcases their brain’s efficiency, with a nervous system that reacts swiftly while processing new information, thus contributing to their high IQ.
According to psychological experts, smiling during sleep requires a strong stimulation of the facial nerves. So, if you see your child smiling in their sleep, it demonstrates that their neural network is exceptionally well-developed and coordinated, surpassing that of their peers.
Kicking the covers during sleep
It is common for parents to feel concerned when they observe their children consistently kicking off their blankets during sleep. Often, this is regarded as a negative sign, with fears that the child might catch a cold. However, in reality, this behavior offers benefits for the development of their brains and is also linked to their cognitive abilities.
When a child remains in the same position for an extended period, it affects their blood circulation, causing discomfort. The child will then automatically adjust their position, signifying that their brain has developed the ability to flexibly coordinate their body. This could correlate with a higher IQ.
Adjusting body position during sleep reflects brain development and flexible body coordination.
Moreover, infants’ limbs are still soft, and their skeletal system is in the development phase. Kicking off the covers is not just a reflex action but also indicates improving muscle strength. This also implies that their behavioral and cognitive abilities are being enhanced. Thus, parents need not worry excessively about this behavior.
However, during cold winter days, when you notice your child has kicked off the covers, it is advisable to gently put the blanket back on to prevent them from catching a chill.
Emotional sensitivity during sleep
It is not uncommon for parents to feel concerned when they observe that their child does not sleep deeply, easily waking up or being startled by slight noises. However, this is not necessarily a negative trait but can actually indicate a positive aspect of their intellectual development.
The reason behind children’s sensitivity to noise during sleep lies in the robust development of their brains. During this phase, their neural cells are highly active, reacting swiftly to external stimuli. This alertness demonstrates that their brains are not only developing well but also have the capacity to efficiently perceive and process information. Hence, even the slightest sound can trigger a response from them.
Brain development leads to sensitivity to noise during sleep.
This suggests that, in the future, your child is likely to be agile, intelligent, and perceptive of their surroundings. Parents should understand that while sleep sensitivity can cause some worry, it also signifies that their child’s intellectual development potential is high.
The Top 3 Traits Sons Inherit From Their Mothers’ Genes.
When a child is born, people often wonder who they resemble more – their mother or father. The truth is, they inherit a mix of features from both parents. However, it’s not uncommon for a child to favor one parent over the other in certain aspects. Some children may bear a stronger resemblance to their mother, while others may lean more towards their father, and this can vary across different features and traits.
