Sitting

Sitting is a basic human resting position. 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, and people who sit regularly for prolonged periods have higher mortality rates than those who do not.

Health effects

The health risks of sitting for long periods of time include obesity, heart disease, diabetes, cancer, and death. These risks are not mitigated by exercise, even though regular exercise is generally beneficial for health. The American Heart Association recommends that people reduce the amount of time they spend sitting and increase their physical activity levels to improve their health.

Posture

The posture of sitting depends on the situation. In general, the back is straight and the body weight is supported by the buttocks and thighs. The knees are bent at a right angle and the feet are flat on the floor. However, the posture can vary depending on the activity being performed while sitting.

History

The practice of sitting has been common in many cultures since ancient times. It was often associated with social status, with higher-status individuals sitting on chairs or stools while lower-status individuals sat on the ground.
