Should I sit at 135 degrees?

Rethinking Optimal Sitting Posture: Embracing the 135-Degree Angle

For decades, we’ve been taught to maintain an upright posture with our backs perpendicular to the floor. However, recent research suggests that this rigid 90-degree angle may not be the most beneficial. Instead, a more relaxed 135-degree sitting position is now being advocated as optimal for spine health and overall comfort.

Benefits of the 135-Degree Angle

The 135-degree angle reduces strain on the spine by promoting better alignment. When sitting at this angle, the lumbar spine (lower back) curves slightly, which helps to distribute weight more evenly and prevent stress on the intervertebral discs.

Moreover, the 135-degree position improves blood flow to the lower extremities and reduces pressure on the sciatic nerve, which can alleviate discomfort and numbness in the legs. It also allows for better hip flexion, which is crucial for activities such as walking and standing.

How to Achieve the 135-Degree Angle

To achieve the 135-degree angle when sitting, follow these steps:

• Adjust the height of your chair so that your feet rest flat on the floor.
• Tilt your pelvis slightly backward, as if you’re trying to tuck your tailbone under.
• Keep your lower back curved and your shoulders relaxed.

Conclusion

Optimal posture is not about maintaining an inflexible 90-degree angle. Instead, it involves finding a position that promotes spine health and overall comfort. Embracing the 135-degree angle is the latest research-backed recommendation for achieving this goal. By reducing strain on the spine and improving alignment, this more relaxed sitting position can help prevent back problems and enhance your well-being.
