Sitting with legs crossed is a common habit for many people, but it may have significant effects on posture and overall health. Two studies explored the consequences of this posture on trunk length, pelvic torsion, and postural alignment. Additionally, advice is given for pregnant women regarding the potential risks of crossing legs while sitting.
Effects of Right-Leg-Crossed Sitting
This study aimed to understand how sitting with the right leg crossed over the left affects trunk length and pelvic torsion in healthy individuals.
Subjects and Methods
- Participants: 30 healthy individuals (18 males and 12 females).
- Procedure: Participants sat on an adjustable chair with their knees and hips at 90 degrees, with minimal clothing for better measurement accuracy. They crossed their right leg over their left knee, and a three-dimensional spinal diagnostic system measured trunk length and pelvic torsion.
Results
The measurements showed significant decreases in trunk length and increased pelvic torsion after sitting with the right leg crossed.
Summary
Sitting with the right leg crossed over the left leads to a shorter trunk length and increased rotation of the right pelvis compared to the left.
Impact of Cross-Legged Sitting on Posture
This study examined how sitting with legs crossed affects posture in adults.
Subjects and Methods
- Participants: 232 adults in their 20s and 30s (84 males and 148 females).
- Procedure: Participants were grouped by how many hours per day they sat with their legs crossed (0, 1, 2, and 3+). Postural alignment was measured in the sagittal plane (side view) and coronal plane (front view).
Results
- No significant differences were found in shoulder joints, knee joints, and heel joints.
- The head was more forward in the 3-hour group compared to other groups.
- Significant differences in shoulder and pelvic alignment were observed in the 3-hour group.
Summary
Sitting with legs crossed for more than three hours a day may lead to shoulder tilt, lateral pelvic tilt, and forward head posture.
Advice for Pregnant Women
Pregnant women are more susceptible to varicose veins. To improve leg circulation and reduce blood pooling in the veins, it is advisable to avoid crossing the legs while seated and to change sitting or standing positions regularly.
Conclusion
These studies highlight the potential negative effects of prolonged cross-legged sitting on posture and health. Understanding these impacts can help individuals make informed choices about their sitting habits to maintain better posture and overall health. Pregnant women, in particular, should be mindful of their sitting positions to avoid additional health issues.
