Our spine routes and protects our nervous system from head to the rest of the body, while bearing the full weight of our head, body, upper limbs through all the activities we do throughout our life. Prolonged incorrect postures tend to degrade, damage and deform our spine and associated muscles and ligaments, which in turns create pressure points and can cause problems to all our internal organs regulated by the nervous system.
Humans in modern society tend to have too little exercises and movements already. Furthermore, the advent of technology and its addicted use, generally creates the exact "prolonged poor posture" condition that's detrimental to our spine. For example, working in front of computer monitor, typing on the keyboard, watching tiny characters, graphics and videos on tablet or cell phone screens, we all tend to stretch our head forward and down, putting lot of stress on our neck and the rest of our spine. We hump our body forward, further bending and stressing our spine. To minimize injury and accumulated damage, we need to keep our head straight up and our spine straight up most of the time, or at least more of the time, whether in motion or in static posture.
Modern 3D accelerometer provides low cost, accurate and convenient tool to track our head and body's activities and postures, particularly if integrated into miniature bio-sensor without wire entanglement and encumberment to movement and activity. Choose a low cost, miniature bio-sensor that can be affixed to convenient and effective body locations, such as center top of forehead for monitoring head postures, or at center of chest for monitoring body postures throughout the day. Simply straighten your head, spine and chest to calibrate for your proper "upright" position first, then you are ready to go and do whatever you normally do, but now with full and accurate recording of your head and chest postures throughout the day. If wireless communication is enabled, the monitoring program may alert you when a preset "prolonged poor posture" is detected, so you can adjust your postures. With determined practices and patience, everyone can improve one's postures and track one's progress with long term log of posture recordings.
