Sleeping on your back might not feel like the most natural sleeping position, but it is considered one of the healthiest. If you’re among the lucky 13% of Americans who are able to fall asleep on their backs, you might even say it’s life-changing. But how easy is it to actually transition to face-up sleeping if you’ve always slept on your front or side?

You probably don’t remember the exact moment you took your first step. Why would you? You’ve taken countless steps since, each more assured than the one before. You have, after all, mastered that all-important life skill: standing upright. What you may not realize, however, is that posture is not something you can simply set and forget. As we age, our bodies can easily slip out of alignment, causing an undesirable stooped posture. Luckily, this is totally reversible if we adopt a few postural best practices.

Picture the scene. It’s the end of a long day and you’re sitting on the couch with your head buried in your smartphone, shoulders slouched forward. All of a sudden, your significant other breaks the silence: “You’ll never guess who I ran into today.” What do you do? Do you straighten your back, look up, and engage them in polite chitchat or do you continue scrolling as if it never happened?

Whether you’re stationed in a cubicle or out in an open space, working 9 to 5 isn’t easy on your mind, body, or soul. Four-thirty rolls around and not only are you mentally checked out, but your aching back is begging for a massage. The pain can be so distracting, it’s all you can think about. Your health suffers, your work suffers, and around and around it goes.
