Plenty of things can kill you, but one of the sneakiest and deadliest causes is something that most of us do for hours every day.

We have an epidemic of back pain due to people sitting hunched over PCs, laptops, tablets and smartphones. Prolonged sitting increases the risk of heart disease, diabetes, obesity and musculoskeletal symptoms.

Good posture allows the muscles around the lungs to stretch, allowing you to take fuller breaths, boosting productivity and improving concentration and focus. But you don’t have to go to a yoga studio to get these benefits.

So instead of feeling fidgety with discomfort, join like-minded colleagues for a 30-minute midday feel good stretch that will leave you tension-free and energized – even if you can’t leave the desk.
