Did you know that there is a correlation between your posture and level of alertness and ability to concentrate? With better posture, not only do you look better and feel better, but you have the ability to sit upright and be more engaged in conversations and learning experiences. You are more alert and aware of your surroundings, and are in a posture or position to make quicker and more precise movements. Just think, when you look around a classroom full of students, you can easily spot the students who are paying attention and learning, compared to those who are disinterested just by observing their sitting posture.
What postural presentation do the students (or worker) who are falling asleep have? They are slumped forward on their desk in a flexion dominant posture, or they are slouched low in their chairs with anterior pelvic translation.
What postural presentation does an alert student (or worker) maintain? Alert students are sitting high in their chairs. They are seated upright and engaged. Their level of engagement is much higher than the students who are half asleep with slumped posture.
Because of the connection of posture and consciousness, research also demonstrates that with proper posture there is better cognitive performance (Muehlhan, 2014). Not only are students who have proper posture in class taking care of their spine, joints and muscles, they also have a higher level of engaged learning and cognitive performance.
The same is true for modern day office workers. While sitting at their desks performing work, by shifting their posture to be more upright, they will be that much more conscious of the work they are doing and engage at a higher level of productivity. Their concentration is improved, as is their lung capacity and circulation. It's a win-win.
