The truth is that crossing one leg over the other, a common sitting posture preferred by many people, may actually do harm to one's health. So while seated, try not to do so any more.Whether it is at the office, in a waiting room or relaxing at home, many people' s go-to posture is one leg over the other, crossed at the knee. If you're like many of us, you spend too many hours of your day seated and for most of that time, you have crossed your legs for comfort.One study found that people who sat with their legs crossed for more than three hours a daywere more likely to lean forward and to round their shoulders. But the research relied on people's own estimations of how long they crossed their legs for.When you cross your legs, you are putting compression and pressure on your leg and knee joints and nerves. The way you sit is a huge determinant of your health and the way your body moves and functions. Sitting with your legs crossed leaves your hips uneven and forces your pelvic bone(盆骨) to rotate. Therefore, the longer you sit in this uneven position, the more pressure is placed on your knee and spine(脊柱), increasing the likelihood that it will develop into a long-term issue.If seated long, then more importantly for you, cultivate and develop a healthy habit of sitting position. And here are the followings. Switch sitting positions often. Take brief walks around your office or home. Gently stretch your muscles every so often to help relieve muscle tension. Keep your feet on the floor, with your ankles in front of your knees. Relax your shoulders; they should not be rounded. Keep your elbows in close to your body and let them be bent between 90 and 120 degrees. Make sure that your back, thighs and hips are fully supported. Try doing those and maybe some of them fit you.
