What is an important factor for maintaining healthy posture while sitting?

Maintaining healthy posture while sitting is crucial for preventing discomfort and long-term musculoskeletal issues. Keeping the feet flat on the floor is an important component of achieving a stable and ergonomic sitting posture. This alignment helps distribute body weight evenly and provides a solid base of support, which in turn aids in maintaining an upright and balanced position.

Having the feet flat allows the knees to be at a right angle, reducing strain on the lower back and promoting proper spinal alignment. This foundation supports the natural curves of the spine and helps prevent slouching or leaning, which can lead to discomfort or pain over time.

Choosing other postures, like sitting on the edge of the chair or leaning forward significantly, could lead to instability or strain, while resting elbows on a desk can sometimes promote slumping if the chair height or desk height is not well adjusted. Therefore, keeping the feet flat on the floor is a fundamental aspect of sitting correctly to support overall postural health.
