Stress balls, regardless of their shape, work on the principle of releasing tension through muscle contraction and relaxation. When you squeeze a stress ball, it requires muscle exertion, and when you release the grip, your muscles relax. This action can improve blood circulation, reduce muscle tension, and distract your mind from stress. So, although the breast shape may elicit a cheeky grin, the science behind boob stress balls is the same as any other stress-relief toy.
Key takeaway: Boob stress balls function similarly to other stress balls, focusing on muscle contraction and relaxation to alleviate tension.
