Many of us spend our days standing and running around. Standing all day can cause a huge strain on your back. When we are standing, the pressure on the intervertebral discs of the lower back is low. Standing uses about 20% more energy than sitting. This causes us to get tired more quickly and want to sit down. Standing at work leads to bending down to pick up objects or stretch up to get overhead objects. In all of these cases there is an increase in the forces on the lower back. That is when the injury is most likely to occur.
If your job requires you to be on your feet all day then try placing one foot at a time up on a footstool or any four- to six-inch block or box. When your foot is elevated, the muscles of the front of your thigh and pelvis relax. These muscles affect the bones and disks of the lower back, when they are allowed to relax, they stop pulling down and compressing your spine. You can also alternate feet every few minutes so that both sides of your back can rest.
