As suggested A study Conducted by scientists at Emory University in the United States, they have investigated the relationship between hours of sleep and children's growth, among other factors, demonstrating that "growth spurts" that occur suddenly are directly related to an increase in the hours the child sleeps, as occurs in periods of illness or fever.
Specifically, the babies' 43 % experienced a small "growth spurt" during times when there was an "extra" or unusual nap, and one in five also grew in each period in which they slept an hour more than usual.
Punctuated growth
While it is true that growth hormone is released at maximum levels during sleep, it is also released in a punctuated manner, and in smaller quantities at intervals of 3 to 5 hours throughout the day.
Thus, the popular perception that children grow during the night is true, as a group of scientists also confirmed in a study done with lambs published in Journal of Pediatric Orthopedics. Experts at the University of Wisconsin Veterinary School in Madison placed a series of sensors on the leg bones of lambs to determine their growth and found that 90% occurred while the animals were sleeping or at rest.
The debate over the study of bone growth prompts us to ask when brain growth might primarily occur and how discontinuous it may be. This study delves into the growth of skills and body parts and how the way of measuring it has shown us a still photo, a series of snapshots, but not the gradual process.
Thus, not only do children grow taller in a punctuated manner, but so do their brains and other parts of their bodies.
