The Allure of the Crossed-Leg Posture
Whether you are at a professional job interview or relaxing at a sports event, crossing your legs is a habitual posture for many. While it may seem like a harmless way to sit, experts suggest that lingering in this position for too long can have implications for your physical well-being.
Valerie Rogers, a physical therapist at Mount Sinai Health System, notes that this position provides a sense of stability. «It gives you a little bit of support so that when you lean forward, for instance, while looking at a computer screen, you don’t have to engage as many muscles to stay upright,» she explains.
The Risks of Prolonged Static Posture
While crossing your legs isn't inherently dangerous, it can lead to issues if it becomes your default position. Ethan Triplett, a physical therapist with Orlando Health, points out that this habit can lead to pelvic imbalances. «When you cross your legs, your body naturally shifts into a slouched posture that extends from your back up to your neck. By placing one leg over the other, you are effectively pushing one side of your pelvis higher than the other, which creates uneven pressure on your glutes,» says Triplett.
Furthermore, experts highlight two other specific areas of concern:
- Blood Pressure Fluctuations: According to Alex Hill, a specialist in pelvic health, crossing your legs causes a temporary spike in blood pressure. This is precisely why medical professionals require patients to keep their feet flat on the floor during blood pressure screenings. However, she clarifies that this is a transient effect and does not lead to chronic hypertension.
- Lymphedema Concerns: For those suffering from lymphedema, keeping the legs crossed for long periods is discouraged. It can exert pressure on blood and lymphatic vessels, temporarily hindering efficient fluid drainage.
The Golden Rule: Your Next Posture is Your Best Posture
The consensus among physical therapists is that the damage stems not from a specific position, but from staying in any single position for too long. Ryan Galvin, a physical therapist with UofL Health, suggests that remaining static for more than 30 minutes is detrimental to the body.
«Your best posture is your next posture,» says Triplett, emphasizing the importance of variability.
To prevent the body from «molding» into a harmful, sedentary shape—a phenomenon often linked to conditions like «tech neck»—experts recommend setting regular reminders to stand up, stretch, and move. While an occasional moment with crossed legs won't cause lasting harm, failing to incorporate movement throughout the day can lead to muscle weakness, tightness in the hip flexors and hamstrings, and long-term instability in your core stabilizers.
