How carry out you like to sit on a chair? Many people prefer to cross one leg end the other. In the 1980s, british comedian Kenny Everett also made the his trademark – extravagantly crossing, uncrossing, then recrossing his foot while pull on in a skirt and also high heels, heralding it to be “all in the best feasible taste”.

You are watching: How to stop crossing your legs

Others favor not come cross your legs at all and even come “man spread” together it’s come to be known, sitting through their knees vast apart top top public transport while the world either next of them are squashed. These men might have chosen a rather curious publicity project launched in the united state in 1999 called “The an excellent Cross-Out” where a dietary supplement agency encouraged civilization to keep healthy by no crossing their legs because that a entirety day.

The perform of suggested results includes elevated blood pressure, varicose veins and also nerve damage, yet is it true?

But is that really any type of healthier to stop crossing her legs? The perform of suggested consequences of security too much time with one knee crossed over the other includes raised blood pressure, varicose veins and also nerve damage, but each of this deserves nearby examination.


Crossing the legs deserve to put pressure on the peroneal nerve in ~ the earlier of the knee, which gives sensation to the lower legs and also feet (Credit: SPL)

Of food it is true the if you spend too much time in precisely the very same position, at some point your leg or her foot deserve to go numb. This is since crossing the legs deserve to put press on the peroneal nerve behind the knee, which provides sensation come the lower legs and also feet. Yet if friend do offer yourself pins and needles this way, that is just temporary.

Maintaining a details posture for many, plenty of hours can but lead to a condition called peroneal nerve palsy resulting in “foot drop” wherein you can’t lift the front part of your foot and toes. But when a examine from southern Korea examined a collection of patients’ notes in stimulate to determine the chef causes, sitting on a chair through one knee end the other didn’t feature. Sit cross-legged top top the floor for hours at a time did. In reality long term numbness is an unlikely consequence of leg-crossing because as shortly as us feel uncomfortable we tend to move.


So how about blood pressure? once you acquire it checked, the physician or nurse tends to ask friend to rest your eight on the chair or table and to uncross your legs, placing your feet flat on the floor. The are afraid is that crossed legs might skew the reading by temporarily raising your blood pressure. Through 2010, seven studies had actually indeed uncovered that leg crossing does an outcome in a greater blood press reading, while an additional study discovered it make no difference. However, plenty of of these research studies were tiny and relied on taking a blood pressure reading just once. Among the larger studies was performed at a hypertension clinic in Istanbul. Researchers there took number of readings v legs crossed and uncrossed. Again, blood pressure was higher when legs to be crossed, yet crucially when the dimensions were repeated just three minute after uncrossing the legs, blood pressure was earlier to the previously levels. The best rise in blood push occurs in people already being treated because that high blood pressure.

Two feasible mechanisms have been suggest to describe why leg-crossing could lead come a temporary increase in blood pressure. One is that the activity of placing one knee over the various other sends blood indigenous the legs approximately the chest leading to an enhanced quantity of blood gift pumped the end of the heart, elevating blood pressure. An different explanation is the blood press rises due to the fact that isometric exercise of the leg muscles (exercise without the joints moving) rises the resistance come the blood passing through the vessels. This could explain why crossing legs at the ankles doesn’t have the very same effect.

In order to establish which of this explanations to be the many likely, a study in Nijmegen in the Netherlands take it a variety of physiological measurements. The team uncovered that resistance in the blood vessels no rise once the heart rate was low and also the legs to be crossed, however the amount of blood leaving the love did, suggesting that the increased blood press is due to crossed legs pushing blood up to the heart.

So cross the foot does show up to reason a temporary increase in blood pressure, however the proof for any long-term consequences simply isn’t there, v one exception. Human being at high hazard of blood clots room advised no to cross their legs for lengthy periods of time because for them, impeding the circulation of blood could increase their danger of a deep vein thrombosis.

But even if crossing her legs doesn’t offer you high blood press in the lengthy term, what around the idea the it can give you varicose veins? The reasons why some people suffer indigenous varicose veins and also others nothing is miscellaneous of a mystery. Typically tiny valves in the blood vessels prevent blood from flowing earlier in the not correct direction, yet if those valves come to be stretched and weakened the blood have the right to pool, bring about the enlarged veins we speak to varicose veins. Cross the legs has actually not been demonstrated to it is in a vital factor. Even if it is or no you get varicose veins seems, partly at least, to be under to genetics.

One study found that civilization who sat v their foot crossed for an ext than three hours a job had bad posture

So if veins, blood pressure and also nerves are not affected by leg-crossing in the long-term, how around the impact on our joints? One study discovered that people who sat through their legs crossed for more than three hrs a day were more likely to skinny forward and to round your shoulders. However the research study relied ~ above people’s own estimations of how long castle crossed your legs for. As I write this, ns sitting at my desk and happen to have actually my legs crossed, yet I would have actually no idea how many hours a day I spend sitting in this way. Much more recent research released this year uncovered that if civilization were instructed come sit up straight while they crossed their legs the postural difficulties were overcome. Of course whether that’s maintained when you have no experimenter standing over you is another matter. Incidentally practically twice as many people reported cross their appropriate leg over your left knee than the other means around.


Slouching no sound good, yet if you are fan of leg-crossing, you can like a quite curious study from the University medical Centre in Rotterdam which found that that could lug benefits. Researchers examined young men and also women together they sat v their legs either straight, crossed at the knee or overcome at both the knee and also the ankle at once. They climate simulated the exact angles that the posture in four embalmed pelvises, which allowed them to measure specifically what our muscle do once we cross our legs. They discovered that cross the foot at the knee boosted elongation in the piriformis muscle to run behind the hip joint by 11% when contrasted with sitting v legs uncrossed, and by 21% when contrasted with was standing (interestingly the stress was slightly less if the legs to be crossed at the fish eye too). The authors think that this rises stability in your pelvic joints in a similar means to tensing the abdominal muscles does.
