The Wall Street Journal explains:
“It’s not as though slouching will give you a hunchback in a day, but “if you do this day after day, and your muscles are not strong, the whole skeleton changes,” Dr. Golubic says. “I’m not aware of any studies that look at the changes in the volume of organs like the liver and spleen when you sit straight or slump forward. But we do know that when you slouch, you project an attitude of depression and low motivation.” When you sit up straight, he adds, “psychologically, your attitude is better.”
So there you have it – yet another reason to sit up straight!
