The reasons that will be featured below can only be described as half-hearted at best. This is because, as true as they all are, they have been shown to matter in cases when crossing your legs has become a permanent habit. This would mean that you cross your legs even when it is uncomfortable to do so.
While crossing your legs is often accorded a healthy respect, especially when it comes to appearing lady-like or professional, this list should reduce the pressure and give you an argument for not reverting to it every time.
It’s All About The Peroneal Nerve:
The peroneal nerve is the major nerve in your leg that passes just below your knee and along the outside of your leg. Crossing your legs will put pressure on this nerve and this pressure can cause numbness and temporary paralysis of some of the muscles in your foot and leg. This will result in your being unable to raise your ankle, giving you a sensation we have come to know as pins and needles.
The feeling is temporary but scientists say that repeatedly sitting with your legs crossed in the same position can cause you to develop long term numbness in your legs from nerve damage, a condition called peroneal nerve palsy resulting in “foot drop” where you can’t lift the front part of your foot and toes.
Your Blood Pressure Will Climb Temporarily:
Crossing your legs could also temporarily cause your blood pressure to go up. This is because the blood in your legs has to be pumped back to your heart against gravity. While that is already a hard enough task for your body, crossing one leg over the other increases resistance to blood flow. As a result, your body has to increase your blood pressure in order to push your blood back up to your heart.
You usually won’t feel any symptoms when your blood pressure goes up, but repeated, drawn-out increases in blood pressure can cause long-term health issues. So if you are planning to sit for a long period of time, do not keep your legs crossed.
The Added Inconvenience Of Back And Neck Pains:
Sitting with your legs crossed puts your hips in a torqued position which can lead to the rotation of one of your pelvic bones. Since your pelvis is the base of support for your spine, it puts unnecessary pressure on your neck and lower and middle back when it’s rotated and unstable. And the longer you sit with your legs crossed, the more pressure you put on your spine, which increases the odds you’ll develop an issue.
