But in fact, many children lack sleep under various "burdens" such as heavy homework, inseparable electronic products and endless extracurricular remedial classes.
At the end of March, 20265438+0, the Ministry of Education issued the "Sleep Order", which took the sleep time of primary and secondary school students as an important part of education management, ensured that primary and secondary school students enjoyed sufficient sleep time, and promoted the healthy development of students' body and mind.
What will happen to children who can't sleep well at night?
Short stature, poor memory, bad temper and low immunity ... In the process of children's growth, the importance of "sleep growth" cannot be ignored.
Sleep is closely related to children's physical development. Growth hormone is mainly secreted by people after they fall asleep. Children who often lack sleep secrete less growth hormone, which affects their height.
Studies have shown that 23: 00 to 24: 00 in the evening is the prime time for children to enter the deep sleep stage, and the secretion of growth hormone is the most vigorous. If you want to have a good physique, you must seize this golden time.
In addition, long-term lack of sleep or sleep disorders can lead to physiological or pathological changes in children's bodies, such as obesity and decreased immunity.
Sleep can promote the connection between children's brains and enhance the function of nerve cells, especially rapid eye movement sleep, which plays a vital role in the early development of children's brains.
REM sleep, namely rapid eye movement sleep, is a sleep stage in which the human cerebral cortex is in an active state.
Rapid eye movement sleep is an important time for children to further strengthen what they have learned during the day. Too little REM sleep will affect the development of children's cognitive, learning and memory abilities.
Long-term lack of sleep has hidden and irreversible damage to children's learning and memory ability, and also affects the neural mechanism of learning and memory function.
In a study of 20 12 (Shen Xiaoming et al., 20 12), researchers found through controlled experiments that-
This means that sleep deprivation will obviously affect the brain function of children and adolescents and damage their brain health, thus further reducing their learning and memory abilities.
Insufficient sleep time will affect the healthy development of children's psychology.
In February, 2020, Feng Jianfeng, Dean of Brain intelligence science and technology Research Institute of Fudan University, published an article in Molecular Psychiatry together with an international cooperation team composed of researchers from the University of Warwick and Oxford University, revealing the relationship between sleep duration during children's development and children's cognitive ability and mental health (especially depressive symptoms).
It is found that the length of children's sleep time is significantly related to children's mental health scores, such as depression score and anxiety score. Children who sleep longer are generally better than those who sleep shorter.
It can be seen that it is really important for children to sleep well, which is more important than finding time to go to remedial classes and interest classes.
