Why you should never cross your legs!

  • One of the reasons for this is that when you put one knee over the other, it sends blood from the legs up to the chest, resulting in a larger quantity of blood being pumped out of the heart, which in turn increases your blood pressure. Another possible explanation is that blood pressure rises because isometric exercise of the leg muscles (exercise when your joints don’t move and muscles don’t change in length) increases the resistance to the blood flow. That is why crossing your legs at the ankles doesn’t have the same effect as when you cross one leg over the other.
    • This position can also lead to pelvic imbalance. Prolonged leg-crossing eventually makes the inner thigh muscle shorter and the outer thigh muscle longer, and puts your joints at risk of moving out of place.
    • The habit of sitting with your legs crossed increases your chances of developing ’spider veins’. Although the biggest contributing factor to varicose veins is your genes, frequent crossing of the legs can lead to inflammation of the compressed veins. There are tiny valves in the blood vessels, that prevent blood from flowing in the wrong direction. When your legs are crossed, the pressure on your veins increases and impedes your blood flow, causing the vessels to narrow and weaken and allowing the back flow of blood. This can cause pooling of blood in the legs and make your veins swell.

    Finally, a study found that sitting with the legs crossed for longer than three hours per day may result in a person developing a stooped posture, lower back and neck pains, and discomfort in their hips.
