Have you ever hit your head on something – or banged your knee into the coffee table – and instinctively started rubbing the sore spot? Well, there’s a reason we do that. It actually helps the injured area feel better faster. That’s according to the McGill University Pain Research Center. Because when we touch our skin in the spot where it hurts, it sends a different kind of signal to our brain, a soothing one – and it travels 100 times faster than pain signals do! So the next time you bang your head or hit your funny bone – rub it for some fast relief.
