The Habit of W Sitting

As children, we often received warnings about sitting in certain positions for our own well-being. One particular sitting position, commonly favored by kids, has raised concerns among researchers for years. Referred to as "W sitting," "television sitting," or "reverse tailor position," it involves sitting with thighs flat on the ground, knees bent, and ankles positioned on either side of the buttocks. The worry is that this sitting style may impact joint development and hinder physical activity later in life. While research findings are conflicting, the general consensus among peer-reviewed studies suggests that any physical changes related to this sitting position are likely to resolve as one grows older—unless, of course, genetic factors contribute to a preference for sitting in this manner. So, let's delve into the data and explore the real risks associated with W sitting.

Over the years, researchers have published papers suggesting that prolonged W sitting can stretch ligaments and potentially lead to hypermobility—a condition where individuals can flex their fingers, elbows, and knees beyond the average range of motion, commonly known as being "double-jointed." While this ability may seem intriguing, it can also be accompanied by pain and health problems. Additionally, this sitting position has been associated with leg and ankle bone rotations, turned-in toes, and flat feet, which some researchers argue could make walking more challenging. Hence, these concerns have sparked further investigation. However, before adopting a new sitting regimen, it's essential to examine these associations and obtain a comprehensive understanding of the topic.

One concern is that lower body rotations resulting from W sitting may hinder movement later in life. However, a study conducted on adolescents and adults found no decrease in running skills among individuals with turned-in toes, also known as pigeon toes, compared to those without this condition. Therefore, it is unlikely to impact physical performance in the long run. Furthermore, several studies suggest that most individuals naturally outgrow rotational issues, loose joints, and flat feet by the age of 10. Hence, if these conditions are observed in children, they often resolve on their own.

Now, let's address the overarching concern that this particular sitting style leads to physical changes in the body. Sitting in the W position is relatively common among children. One study, which examined over 1,000 preschoolers, discovered that 63.3% of them sat in the infamous W style. However, only 5.9% of the children had turned-in toes. Therefore, the percentage of children with physical traits associated with W sitting is considerably smaller. Moreover, of the children with turned-in toes, 80.6% sat in the W position. Hence, sitting in the W position does not necessarily imply the development of turned-in toes or other rotations since only a small portion of those who sit this way exhibit such physical traits. Interestingly, there are more individuals with turned-in toes sitting in the W position compared to those sitting cross-legged. This suggests that people who are already rotated may find the W sitting position more comfortable. If one's legs or feet are naturally positioned at different angles, they may discover alternative sitting postures that suit their body, rather than attempting to conform to positions that some individuals find comfortable. This adaptation is particularly evident in individuals diagnosed with Hypermobility Spectrum Disorders, including Joint Hypermobility and hypermobile Ehlers-Danlos syndrome.

These conditions are hereditary disorders affecting the connective tissue, which plays a vital role in proprioception—the body's ability to sense the position of muscles and body parts. Although these disorders can also result from surgery or traumatic events, some individuals are born with a predisposition for hypermobility. In the 21st century, researchers have identified more than a dozen new genes associated with Ehlers-Danlos syndrome and have traced its inheritance through family lines. Therefore, regardless of sitting posture, some individuals may be hypermobile due to genetic factors. However, sitting posture might be the least of their concerns if they live with a Hypermobility Spectrum Disorder. Excessive flexibility can disrupt spatial self-awareness, weaken muscles, and render soft tissues fragile, creating a perfect storm for injuries. Fatigue, joint sprains, dislocations, and chronic pain are common experiences. However, not everyone diagnosed with a Hypermobility Spectrum Disorder will encounter all these obstacles, as different types of Ehlers-Danlos Syndrome exist. It's important to note that W sitting alone does not condemn individuals to experience all these symptoms. While people with joint hypermobility are more likely to adopt this sitting position, it does not mean that everyone who does is hypermobile. Therefore, the "W" in W sitting does not necessarily stand for "worry."

In conclusion, the concerns surrounding W sitting should be approached with caution. While there have been studies highlighting potential risks, it is crucial to consider the broader context. Most individuals naturally outgrow any physical changes associated with this sitting position during childhood. Moreover, the relationship between W sitting and specific physical traits is not as straightforward as it may seem. Factors such as genetic predispositions and comfort for individuals with existing rotations can influence the choice of sitting posture. For individuals diagnosed with Hypermobility Spectrum Disorders, sitting posture becomes a secondary concern amidst a range of other challenges. Therefore, it is essential to gather a comprehensive understanding of individual circumstances and consult healthcare professionals for personalized advice. Ultimately, W sitting should not be regarded as an inevitable cause for worry.
