Washington: Clenching your fist could be enough to help boost your memory, a new study has claimed. Clenching your right hand may help form a stronger memory of an event or action, and clenching the left may help you recollect the memory later, according to researcher Ruth Propper and colleagues from Montclair State University in US. Participants in the research study published in the journal PLOS ONE were split into groups and asked to first memorise, and later recall words from a list of 72 words. There were four groups who clenched their hands, one group clenched their right fist for about 90 seconds immediately prior to memorising the list and then did the same immediately prior to recollecting the words.
