Children Do Grow during Sleep

The experts from the University of Oslo have proved that children do grow mainly during sleep. Of course, they grow during the day as well, but the rate of growth at night is 43% higher than of that during the daytime.

It has been found in the course of the experiment that girls grow faster than boys. And with the growth, children gain weight and fat mass in particular. However, the researchers have not managed so far to clarify the mechanisms of sleep at night which are responsible for the growth of children and adolescents. The experts explain that the production of growth hormone happens mostly during sleep.

It has been noticed that children who suffer from certain sleep disorders grow not so fast. In addition, the immune system is strengthened during sleep. Therefore children need plenty of sleep to be healthy and keep growing.
