First of all, the correct sitting posture should start with the choice of sofa. You should choose a sofa that suits your height and figure. If you are tall or thin, you can choose a deeper seat, which will make your spine in a normal natural curve state. The height and width of the seat are also important. Generally speaking, the height of the seat should be level with your knees, and the width should be able to bear your weight better.
Secondly, the correct sitting posture should be upright, with hips resting on the back of the chair and spine in a straight line. This will help to reduce the pressure on the spine and avoid unnecessary compression and strain.
Third, put your feet on the floor so that you can arrange them clearly and bend your knees slightly. At the same time, we can also put a foot pad under our feet to better relieve the fatigue of our legs.
Finally, we can put a backrest pillow behind the waist to support the waist. This can not only reduce the pressure on the waist, but also further support the spine and prevent the abnormal excessive inward depression or outward protrusion of the lumbar spine.
Correct sitting posture can not only reduce physical fatigue, but also avoid discomfort symptoms such as back pain. In daily life, we might as well pay more attention to our sitting posture and better protect our spine and health by adjusting our sitting posture.
