A new study has discovered that simply clenching your fists can have a positive effect on memory.
The unexpected revelation came after an experiment was conducted in which 50 volunteers attempted to recall a long list of words. Researchers found that those who clenched their fists for 90 seconds beforehand were consistently able to remember more of the words than those who didn't. It is thought that this action helps to activate specific brain regions associated with memory processing.
"Clenching your right hand immediately prior to learning information and clenching your left hand immediately before recalling it would be helpful to improve memory," said lead scientist Dr. Ruth Propper.
"Memory can be improved simply by clenching the fists, a study suggests."
