Another “quick and easy” remedy for something a lot of us suffer with.
Forget so-called ‘good’ posture, generally keeping active is much more important, advises a chiropractor
And here comes the part that makes a whole lot of sense;
Even if you struggle to fit in regular exercise, there are adjustments you can make to everyday life to take care of your back. Taking the stairs instead of a lift, for example, or getting off your bus a few stops early and walking the rest of the way to work. If you’re stuck in the office all day, taking a “micro-break” every half an hour is vital. This could be just standing up and spending; an easy stretch for the office is the upper trapezius neck stretch, which targets the muscles that commonly become tense after sitting for a long time.
And I’m probably the worst violator of the suggestion to take frequent mini-breaks during my sessions at the computer. (Gonna do one right now.)
