Most of us sit cross-legged without thinking. But new research suggests this innocent habit may actually reduce blood flow to your brain. When you cross your legs, you compress major blood vessels in your thighs. This raises blood pressure and can even lead to nerve compression. Scientists in Korea found that sitting like this for long periods decreased oxygen delivery to the brain. That’s why you might feel lightheaded or mentally “foggy” after. I tried breaking the habit—using a footrest instead of crossing my legs. Within weeks, my posture improved, back pain lessened, and my afternoon headaches were gone. It sounds small, but how you sit can literally affect how your brain functions. Next time you catch yourself crossing your legs, remember: your brain might thank you if you stop. #BodyHacks #BrainHealth #PostureMatters
