Many women have been taught to sit with one knee crossed over the other, a position often deemed 'ladylike.' However, health experts now warn that this common posture may be detrimental to your health. Anisha Joshi, an osteopath with 20 years of experience, explains that sitting cross-legged on a chair creates asymmetry in the body. This position rotates one hip while the other remains neutral, leading to an imbalance in the pelvis, hips, and lower back. Over time, this can cause tightness in the hip rotators, uneven load on the lower spine, and discomfort that may not be immediately linked to sitting habits.
How Cross-Legged Sitting Affects Blood Flow
Crossing your legs, particularly at the knee, can temporarily increase blood pressure. The top leg exerts pressure on the veins of the bottom leg, potentially impeding circulation. This effect, while usually temporary, could be a concern for individuals with existing circulatory issues.
Historical Etiquette vs. Modern Health
Interestingly, traditional etiquette experts like Emily Post from the 1920s advised against crossing knees, stating that no lady of dignity should do so. Instead, they recommended the 'Duchess Slant,' popularized by Princess Diana and Kate Middleton, where knees, legs, and ankles are kept together and slanted to one side.
What Is the Best Sitting Position?
For prolonged sitting, Anisha Joshi recommends placing both feet flat on the floor, with knees at hip height or lower, and supporting the lower back lightly. However, she emphasizes that movement is more critical than achieving a perfect posture. Changing positions regularly, shifting weight, stretching legs, or standing up every 30 to 40 minutes helps prevent muscle fatigue, maintain circulation, and keep joints healthy. The problem is stillness, not just the shape of your posture.
Test Your Posture: Squat Duration by Age
If you're curious about your overall posture and strength, consider testing how long you can hold a squat. For ages 20-39, beginners can hold for 30 seconds to 1 minute, intermediate for 1-2 minutes, and advanced for 3-5+ minutes. Ages 40-59: beginner 20-45 seconds, intermediate 45 seconds to 2 minutes, advanced 2-4 minutes. Ages 60+: beginner 10-30 seconds, intermediate 30 seconds to 1 minute, advanced 1-2 minutes.
