Having trouble dealing with a stressful situation? Then try clenching your fists to take the edge off. Tightening a muscle or a group of muscles has been shown to be very effective in helping people to deal with stressful situations.

Researchers from the University of Chicago and the National University of Singapore put volunteers through a variety of stressful situations, ranging from having their hands dunked in ice water, to eating unpleasant foods, to having to watch footage of injured children.

In each case, half the volunteers were told to clench a muscle during the experiment. The muscle-clenchers dealt with the each scenario more positively. The study's authors concluded that, "The mind and the body are so closely tied together, merely clenching muscles can also activate willpower."
