Resting position of human body weight, primarily supported by buttocks in contact with objects

Sitting is a basic action and resting position in which the body weight is supported primarily by the buttocks in contact with the ground or a horizontal object such as a chair seat. The torso is more or less upright. Sitting for much of the day may pose significant health risks, with one study suggesting people who sit regularly for prolonged periods may have higher mortality rates than those who do not. The average person sits down for 4.7 hours per day, according to a global review representing 47% of the global adult population.
