Crossing your legs is an extremely common habit. While you may find it comfortable to sit with one knee crossed over the other, it might be causing health problems that you are not aware of.
A study published in Blood Pressure Monitoring stated that sitting with your legs crossed can increase your blood pressure. The reason is that crossing one leg over the other increases resistance, making it even harder for the blood to circulate and increase your blood pressure. Thus, you shouldn't have your legs crossed for more than 15 minutes, and it's important that you get up and walk around at least once every hour.
Crossing your legs can also lead to neck and back pain. Ideally, it's best for our bodies to sit with our feet planted flat on the floor. When you sit with your legs crossed your hips are in a twisted position, which can cause pressure on your lower and middle back and neck.
You also might notice that when you sit with your legs crossed for long periods of time your feet and legs get painful. This is because when one leg sits on top of the other, it causes pressure on the veins and nerves in your legs and feet. While the feeling of discomfort may only last a minute or two, repeatedly crossing your legs until they feel numb can cause permanent nerve damage.
So next time you sit down, try to get yourself in the habit of sitting with both of your feet on the floor. Not only will it help your posture and stability, but it will also save your health in the long run.
