Why Don't Japanese People Get Knee Pain While Sitting with Legs Bent Under Them for Eating?

The prevalence of knee pain among individuals who frequently sit with legs bent under them, as seen in traditional Japanese sitting postures, may vary due to factors such as genetics, lifestyle, joint health, and cultural practices.

Factors Influencing Knee Pain

While the formation of knee pain depends on a variety of factors, including genetic predispositions and overall joint health, the cultural practices of sitting in certain postures can play a significant role. Traditionally, the Japanese sit in a posture known as Seiza, which involves kneeling with the heels under the buttocks. However, more commonly, they sit cross-legged for meals.

Understanding Seiza

Seiza is a traditional Japanese sitting posture often associated with formal or ceremonial occasions, such as performing tea ceremonies or sitting in religious settings. It is less common in everyday dining. People in Japan, especially children, are used to sitting in this position since their early years. While they do experience some knee discomfort, particularly as they age, modern Japanese tend to use collapsible benches or cushions to support their knees, reducing the risk of discomfort.

Modern Adaptations and Cultural Shifts

Contemporary Japanese have shifted away from the rigorous adherence to traditional postures. According to cultural norms, it is more prevalent for people in Japan to use supports or cushions when sitting in a kneeling position. This shift is evident in stores that sell religious goods, where a variety of collapsible benches and cushions are available for purchase.

Lifestyle and Usage Frequency

The frequency of sitting in these positions also plays a role in knee pain. While younger generations in Japan are still accustomed to sitting with their legs bent under them for meals or certain cultural practices, contemporary lifestyles have led to a decline in the frequency and duration of such activities. This reduction in usage reduces the likelihood of knee pain associated with long-term sitting in these positions.

Conclusion

The prevalence of knee pain in individuals who frequently sit with their legs bent under them, such as in Japan, is influenced by a combination of factors, including genetic predispositions, lifestyle habits, and cultural practices. While traditional postures like Seiza can lead to some discomfort, particularly among the elderly, modern Japanese often use supports and cushions to mitigate the risk of developing knee pain. Understanding these factors can help individuals make informed decisions about their sitting habits and seek appropriate medical advice when needed.
