A study revealed that although they are resting, the brain does not.
Adequate growth is based on three principles: a good diet, protection and emotional security and a correct sleep habit. And in the latter case, sleep not only helps to repair energy and help children grow.
Good mental development is also achieved through sleep, as it facilitates neurological maturity, preparing children to process and explore the environment in increasingly sophisticated ways. Sleep plays a very important role in strengthening the memory of everything learned during the day while awake and finally, children process the stimuli of the senses and learn about their environment even when they are asleep.
So, according to various studies, the brain works all the time.
