Varicose veins, which are bulging, twisted veins, are often blamed on crossing your legs. This is a myth. They are actually caused by damaged valves in your veins that struggle to pump blood back to your heart.

While most of the common fears are unfounded, there is one potential side effect of crossing your legs: poor posture. Sitting with one leg over the other for long periods can cause your pelvis to rotate and tilt, which may lead to pain in your lower back.

Poor posture, caused by repeatedly crossing your legs, can potentially lead to a slight misalignment of your spine over time. When your posture is off, your muscles have to work harder, which can cause stiffness and discomfort.

The biggest takeaway is not that you must stop crossing your legs entirely, but that you should avoid staying in any one position for too long. Whether your legs are crossed or not, sitting for very long periods can increase your risk of problems like varicose veins.

Crossing your legs is not an immediate health risk and will not cause a medical emergency. While it can temporarily raise your blood pressure and contribute to poor posture, it’s a habit that is easily managed by changing positions regularly.
