I was watching the Pregnancy video (which is really cool) and noticed at 2:11 into the video they state: “The fetus’ continual movement in the womb is necessary for muscular and skeletal growth.” Very true. Without this continual twisting, turning, kicking, and pushing the developing fetus would not develop properly. The same is true for a newborn baby after they are born. They twitch, wiggle, flex and extend while awake and even in their sleep and this continual movement is necessary not only for musculoskeletal development but also for proper brain development. What our society forgets is that continual movement is necessary not only for initial development but also for continued health throughout our lives. When we stop moving, we start dying is the simple way to look at it. Everything in the human body depends on movement. Muscles, bones, nerves, heart, lungs, digestive system, lymphatic system, etc all rely on continual movement. Without movement, they systems get weaker, stiffer, slower, less able to do their job, and this negatively impacts our overall health.
