2. You’ll be Lopsided and Your Posture Could Suffer
In a perfect world we would all switch sides when carrying out heavy handbag, but in reality, we all have a dominant side and we favor that arm and shoulder when lugging our stuff. And because you typically carry your bag on one side, the muscles on that side will naturally be stronger. We’re not saying you’ll look completely lopsided, but as far as your muscle strength goes, you will be uneven. And that’s not a good thing both for your appearance and for your posture. As Huff Post reports, according to New York-based chiropractor Dr. Karen Erickson, “we see asymmetry in posture—like, one shoulder’s higher than the other—from this chronic forcing of the muscles on one side to become more developed than the muscles on the other side.”

3. It can be Hard to Find Things
Forgetting about your health for a moment, carrying around a massive bag that is overloaded with stuff creates clutter that can affect your time and your levels of stress throughout your day. The more crap you have in your bag, the harder it is to find the things you really need. And the longer you have to dig around to find your keys or your phone the more time you waste and the more you’ll have anxiety as you search frantically for what you need. In some instances less is more, and this is one of those times.
