Several years ago, scientists at the University of Wisconsin’s School of Veterinary Medicine in Madison placed sensors on the leg bones of lambs in order to measure their bone growth. Ninety percent of bone growth occurred while the animals were sleeping or resting! As published in the Journal of Pediatric Orthopedics, the authors of the study noted that when animals are lying down, there is less pressure on the growth plates and the bones can elongate.
Children have been heard to complain of “growing pains” at night. Well, if this study is on track, they are the result of actual bone growth.
