Avoid Long Sitting – General Tips

Sitting is one of the worst positions for the body to maintain. After just 20 minutes hunched over in a chair, blood pools in the legs and immense pressure builds on the spine.

Why to Avoid Long Sitting

Prolonged sitting causes discomfort, numbness and spine misalignment.
Holding the body upright also increases tension in major muscles and joints.
Negative reactions like cardiovascular disease (because of less blood flow), tightened hip flexors, shortened hamstrings, pinched nerves and many physical injuries.
Bad posture makes the sitting disease even worse resulting in Slipped discs.

Handy Tips about Sitting

Stand at least every hour at your desk.
Do simple stretches throughout the day such as placing your hands on your lower back and stretching backwards.

Get moving! Make conference calls on your feet or suggest a moving meeting — walk up and down the hall.
When seated, make sure you maintain good posture with your butt all the way back to the chair, feet flat on the floor, head straight and with lower back naturally arched inward.

Why to Stand

"The weight is distributed in a standing position," says Kelly McGonigal, Ph.D., a health psychologist at Stanford University and a leading expert in neck and back pain.

Sit Like this

Either roll up a thick sweater or use a small pillow behind your back to allow your lower back to curve inward. Aim to insert it in between the small of your back and the chair.

Three natural curves of a healthy spine

The neck is forward, the upper back has an outward curve and the lower back is inward. Elbows are at the sides of the body and shoulders are relaxed — holding shoulders upright for a long time will strain the area.
