Poor Oxygenation – Improper positions can also result in poor oxygenation. The lungs expand and contract to accommodate the volume of air coming into the body and to do this the abdomen has to have plenty of space for the diaphragm to move. Improper sitting positions like slouching or leaning on the side of the body can apply pressure on the abdomen, restricting the movement of the diaphragm and resulting in shallow breathing. As a result, the body cannot take in or dispel the right amount of air the body needs causing the diaphragm to work harder than it needs to.And make sure you use the Office Chair Singapore of Ardent Office Furniture (AOF) Singapore.
