“Stand up straight.”
A phrase we may have heard as we stood in line outside of our elementary classrooms or as we prepared to enter a family gathering with our parents.
Yet, our spine itself isn’t actually straight. Perhaps the phrase should be: “Stand up curved.”
Mayfield Clinic describes the curves of the spine as forming an S-shape. Viewed from the side, the cervical and lumbar spines have a lordotic, or a slight inward curve, and the thoracic spine has a kyphotic, or gentle outward curve. (1)
When the curvature of the spine becomes too pronounced in one direction or the other, bad posture occurs. Remaining aware of our spine’s mechanics and of our activities (looking at a phone, computer, television, sitting improperly) can prevent a curvature from appearing. Here is more detailed information to consider.
