Almost half (45%) of women cross their legs most or nearly all of the time, even though 75% of these women know it is bad for them. It is a matter of routine rather than manners for women, over 70% of who claim they do it out of habit, not thinking or realizing what they are doing!
So why is it so bad for you?
When you cross one leg over your opposite knee, it raises one hip and puts increased pressure on the other, which causes your spine to shift its position. If you sit like this for extended periods of time (and most of us do), it can result in lower back, pelvic, hip and knee pain. By shifting the position of the hips, pelvis and spine, crossing your legs shortens the muscles on one side of your lower back. If left in this position, these muscles become chronically shortened, and can lead to a great deal of back pain and spasm. This position also increases the pressure put on your sciatic nerve, which runs through your lower back, buttocks, and down both legs to the feet. Scientists have proven that it only takes the pressure of the weight of a dime on a nerve to cause 60% altered function in that particular nerve.
