Answer 2

First and foremost, I promote good posture with all young people because it shows a sense of pride. A good self esteem. When someone walks into the room, I can get a good sense of how they feel about themselves, simply by how they carry themselves. This is especially important in job interviews, growing in your career, and in your general health. Good posture is good for all of your organs. Think about it. If you are scrunched over all of your organs are being scrunched. Your back is out of alignment which can cause illness and pain.

Good posture helps reduce back pain
Correct posture is a simple but very important way to keep the many intricate structures in the back and spine healthy. It is much more than cosmetic—good posture and back support are critical to reducing the incidence and levels of back pain and neck pain. Back support is especially important for patients who spend many hours sitting in an office chair or standing throughout the day.

Problems caused by poor back support and posture
Not maintaining good posture and adequate back support can add strain to muscles and put stress on the spine. Over time, the stress of poor posture can change the anatomical characteristics of the spine, leading to the possibility of constricted blood vessels and nerves, as well as problems with muscles, discs and joints. All of these can be major contributors to back and neck pain, as well as headaches, fatigue, and possibly even concerns with major organs and breathing.

Identifying good posture
Basically, having correct posture means keeping each part of the body in alignment with the neighboring parts. Proper posture keeps all parts balanced and supported. With appropriate posture (when standing) it should be possible to draw a straight line from the earlobe, through the shoulder, hip, knee, and into the middle of the ankle.

Because people find themselves in several positions throughout the day (sitting, standing, bending, stooping, and lying down) it's important to learn how to attain and keep correct posture in each position for good back support, which will result in less back pain. When moving from one position to another, the ideal situation is that one’s posture is adjusted smoothly and fluidly. After initial correction of bad posture habits, these movements tend to become automatic and require very little effort to maintain.
