The seat back Angle refers to the Angle between the back of the seat and the horizontal plane, which directly affects the comfort and health of our sitting posture. A suitable seat back Angle can effectively reduce the body burden, reduce back muscle fatigue, avoid cervical and lumbar spine injury.
In general, the seat back Angle should be between 90° and 120°. If the Angle is too large, such as too much tilt, it will cause the body to lean forward too much, which is easy to cause the spine to bend forward, aggravate the spine pressure, and cause cervical and lumbar pain. If the Angle is too small, the Angle between the back of the seat and the horizontal plane is less than 90°, it may cause the body to fall back, resulting in backward bending of the cervical and lumbar vertebrae, and it is also easy to cause fatigue and discomfort in the lower back.
Therefore, choosing a suitable seat back Angle is very important for our health. In the case of office or long time sitting, the back Angle of the seat should be adjusted according to individual physical conditions and habits. In general, the Angle between the back of the seat and the horizontal plane should be moderate, so that the entire back can be evenly supported and the spine can maintain its natural state.
In addition, in the case of sitting for a long time, it is recommended to regularly get up and do some stretching exercises to relieve physical fatigue and maintain physical health. The correct adjustment of the seat back Angle and the maintenance of good sitting habits have an important impact on our health and body. Let's focus on the seat back Angle from now on to take care of our spine health.
