Questions & Answers

Q: Why is good posture important for our health?

Good posture helps maintain the natural curvature of the spine, reducing strain on the muscles and ligaments, supporting proper organ function, and preventing back pain and other health issues.

Q: Can changing sitting posture impact metabolism or help with weight loss?

Simply changing sitting posture has a minimal impact on baseline metabolism and won't lead to significant weight loss. However, regular movement and varying posture throughout the day can help improve overall health.

Q: How does "text neck" affect our posture and spinal health?

"Text neck" occurs when we bend our neck sharply to look at screens positioned too low. This posture can disrupt the natural curvature of the neck, leading to pain and discomfort.

Q: How can wheelchair users maintain good posture?

Wheelchair users can benefit from proper back support and wheelchair designs that support spinal curves. This helps increase lung capacity, arm mobility, and ease of propulsion.

Summary & Key Takeaways

• The spine is not completely straight, but curved in an S shape, with primary and secondary curves that develop from birth to support balance while standing.

• Spinal curves can change in adulthood, such as during pregnancy, and can even adapt to accommodate different weight distributions, as seen in people with dextrocardia.

• While there isn't a universally agreed-upon "best" posture, regularly varying between sitting, standing, and walking can help reduce the incidence of lower back pain.
