Table 1

Sitting postures and their effects.

Posture arrangement	Description	Pressure points	Possible health problems
Ideal posture	Back and legs make an angle of 90	Balanced pressure on buttocks, arms, legs, and back	No harm
Forward leaning	The slope of 40, no back support	Knee, abdomen, shoulder, upper spinal cord	Knee issue, back pain, back stiffness
Backward leaning	Upper back against chair backrest	Lumbar spine and neck	Spinal dysfunction, the strain on soft tissues
Right-leaning	Leaning to the right exerts more pressure on the right side of the body	Liver, stomach and right kidney, lower spinal cord	Respiratory issues, muscle imbalance, tightness of right muscles, spine curve to the right
Left-leaning	Leaning to the left exerts more pressure on the left side of the body	Spleen, left kidney, lower spinal cord	Respiratory issues, muscle imbalance
