But without knowing, this habit of yours can actually have some negative effects on your health. This is what the research has found.
* It Causes Back And Neck Pain
You are liable to have back and neck pain if you cross your legs frequently. According to some research, the hips are slightly twisted when in this position and can cause imbalances in the pelvis. This will put pressure on the spine and that is likely to lead to back pain and even neck pain later on.
* It May Temporarily Raise Your Blood Pressure
As one of the experts explains, the blood in your legs has to be pumped back to your heart against gravity. That’s already a tough enough task for your body, but when you cross one leg over the other, it increases resistance to the blood flow. As a result, your body has to increase your blood pressure in order to push your blood back up to your heart.
* It Can Cause Nerve Damage
The sciatic nerve is the largest in the human body and stretches from the lower back right down to our feet. One branch of the sciatic nerve is the peroneal nerve. Any pressure on this such as leg crossing can cause numbness and tingling and over time may actually damage the nerve.
* It May Be Linked To Spider And Varicose Veins
Crossing your legs increases the pressure on your veins that are responsible for returning blood back to your heart. The pressure of one leg on top of the other impedes your blood flow, which can weaken or damage the veins in your legs. If the veins are damaged or weakened, the blood can leak into them and collect there, causing spider veins or exacerbating existing ones.
