Your sitting and standing posture affect your height. Poor posture will make your look shorter than your actual height.

What you need to do
Always sit and stand in an upright position.

Why
The ideal posture is a position with your shoulders back, back straight and head in line with your body.

Good posture can not only straighten your spine, relax your muscles and increase your height, but also prevent neck and back pain caused by poor posture.
