Memory can be improved simply by clenching the fists, a study suggests.
Clenching the right hand for 90 seconds helps in memory formation, while the same movement in the left improves memory recall, say US psychologists.
In an experiment, 50 adults performed better at remembering words from a long list when they carried out these movements.
The researchers think clenching a fist activates specific brain regions that are 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," Dr Propper told BBC News.
Past research has shown that right hand clenching activates the left hemisphere of the brain, while left hand clenching activates the right hemisphere.
This has been associated with emotions - for example right hand clenching with happiness or anger, and left hand clenching with sadness or anxiety.
Memory processing is thought to use both sides of the brain - the left for encoding memories and the right for retrieving them.
