There is this idea that swearing is just bad language and that there is no need for it at any point. However, while some choice words may not be pleasant on the ears of different individuals, research has shown that it may not all be as bad as you think.
Instead, what the research has unveiled is that swearing while you are in pain could actually prove to be beneficial for the individual who is in pain. It seems that the act of swearing magically releases pain-relieving endorphins, so whatever is hurting you will no longer appear to be as bad.
So, the next time you bang your toe on the chair leg or stand on that up-turned plug, just remember to swear, and the pain will all be over in next to no time at all.
