Clenching your fist could be enough to help you get a grip on your memory.
Research suggests that balling up the right hand and squeezing it tightly actually makes it easier to memorize lists. Later, when it is time to retrieve the information, it is the left hand that should be clenched.
It is thought the movements activate brain regions key to the storing and recall of memories.
The American researchers suggest those who are short of a pen and paper should try the trick when attempting to commit a shopping list or phone number to memory.
Lead researcher Dr Ruth Propper said: ‘The findings suggest that simple body movements – by temporarily changing the way the brain functions – can improve memory.'
