How are you sitting right this second? Are your shoulders hunched in as you lean toward your lap? Is your neck straining downward to face the screen? You may have thought the only reason parents and teachers instructed you to sit up straight was to exert confidence, but how bad posture affects your body physically may be a much bigger concern for your health. Personally, I’ve never once looked at the way my husband hurdles his entire body forward when he’s playing video games and thought, “Wow, his self-esteem must be low.” Instead, I knowingly shake my head because, in a few hours, I know for sure that his neck is going to be feeling one hell of a kink. Sure, posture is about self-presentation to an extent, but I’d argue the physical side effects are what you should really be paying attention to.
Generally speaking, your posture is something you probably don't think about too often. I know myself, and unless someone outwardly comments on the way I'm sitting, I hardly notice it myself. But seriously, do yourself a favor: If you aren't already, sit or stand up tall, with your shoulders back. Notice how that feels. If it's uncomfortable, maybe even a little sore after a minute or two, you're going to want to fix that ASAP, because if you think a few minutes of perfect posture hurts, the following physical struggles are what you can expect from dismissing your stance altogether.
