Sunshine With Me Office Chair

In the TV series 'Sunshine With Me', the specific brand or model of the swivel office chair used by Sheng Yang is not explicitly mentioned, but the show discusses the correlation between such swivel chairs and spinal issues, particularly lumbar problems. The following analysis is conducted from the perspectives of traditional Chinese medicine (TCM) and ergonomic principles:

TCM Perspective on Swivel Chairs and Lumbar Problems

According to TCM theory, lumbar problems are often associated with 'imbalance of tendons and bones' and 'stagnation of qi and blood'. Prolonged poor sitting postures, such as leaning forward or having a hollowed-out lower back, can disrupt the local circulation of qi and blood, leading to pain or strain. While the flexibility of swivel chairs facilitates movement, a lack of lumbar support or habitual twisting of the body by the user can exacerbate excessive stretching or contraction of the lumbar muscles, resulting in 'dynamic strain'. For example, frequent body rotation subjects the lumbar spine to additional torsional forces, and if the core muscle strength is insufficient, it can lead to uneven distribution of intervertebral disc pressure, accelerating degenerative changes.

Ergonomic Risk Factors

1. Lack of Lumbar Support: Most ordinary swivel chairs are not designed with support structures tailored to the lumbar curve, leaving the lower back in a 'hollowed-out' state during prolonged sitting, which increases pressure on the intervertebral discs.
2. Dynamic Postural Instability: The swivel function may induce users to frequently adjust their sitting postures, such as twisting or leaning forward, leading to sustained tension in the lumbar muscles, disrupting 'static balance', and triggering chronic injuries.
3. Inappropriate Seat Height and Depth: If the seat height is too high or the depth is too shallow, it may force the user's legs to dangle or the lower back to protrude forward, further increasing the lumbar burden.

Prevention and Improvement Recommendations

1. Choose Ergonomic Seating: Prioritize swivel chairs with adjustable lumbar supports, seat depths, and heights to ensure the lower back is in contact with the chair back, reducing the sensation of hanging in the air.
2. Control Usage Time: Take a break every hour of sitting for 5-10 minutes to perform lumbar stretches, such as the cat-cow stretch or lateral bends, to promote qi and blood circulation.
3. Strengthen Core Muscles: Enhance abdominal and back muscle strength through exercises like planks and bridge poses to improve lumbar stability.
4. TCM Adjunctive Therapy: If lumbar discomfort has already occurred, try heat therapy, tuina massage, or moxibustion (at acupoints such as Shenshu and Mingmen) to dredge meridians and relieve pain.

Although the show does not specify the brand or model, it highlights the potential impact of 'poor sitting postures and tool selection' on lumbar health, which is worth considering and adjusting by viewers based on their own circumstances.
