So here are ten (mostly) very easy ways to improve your memory that are supported by research.
With two or three exceptions, most people can do these with very little effort or expense.
1. Clench your right fist
If you squeeze your right hand into a fist during learning, it can aid memory.

Later on, to aid recall, squeeze your left hand into a fist.
In study by Propper et al. (2013), participants who squeezed their right fist during learning and their left during recall, did better than control groups clenching the other fist or not clenching at all.
2. Chew gum
Chewing gum can help you stay focused on a task and so improve your memory.
A study by Morgan et al. (2013) tested the audio memory of those chewing gum, compared with those who didn’t.
The gum chewers had improved short-term memory compared with non-chewers.
3. Go to sleep
One of the many benefits of sleep is that it makes memory stronger.
That’s because the brain is surprisingly busy during sleep and one of the things it’s doing is working on our memories.
Not only does sleep make our memories stronger, it also restructures and reorganises them.
Studies have shown, for example, that people are more likely to dream about things with a higher value to them, and are subsequently more likely to recall those things (Oudiette et al., 2013).
And, if what’s important to you is learning to play the piano, you could even try listening to the piece while you nap, as one study has shown this helps cement the memory (Anthony et al., 2012).
More on how the mind learns during sleep.
4. Go for a walk
Many people suffer memory problems with advancing years.
But, walking just six miles a week helps to preserve memory in old age.
One study has found that older people who walked six to nine miles per week had greater gray matter volume nine years later than those who were more sedentary (Erickson et al., 2010).
5. Stop smoking
Although the physical benefits of quitting smoking are well-known, it’s less well-known that it will also benefit memory.
That’s because smoking damages the memory, and quitting can almost restore it to normal function (Hefferman et al., 2011).
That’s one more reason to quit (or to be happy that you don’t smoke).
6. Ignore stereotypes
If you think your memory will get much worse with age, then it probably will. It’s a self-fulfilling prophecy.
Older people who are reminded of stereotypes about age and memory perform worse in tests (Hess et al., 2003).
So, suffer fewer memory problems with age by paying no heed to the stereotypes.
7. Read Facebook posts
One study has found that people’s memories are much stronger for posts on Facebook than for sentences from books, or even people’s faces.
Mickes et al. (2013) found that Facebook posts were probably easier to remember because they were ‘mind-ready’: they were already in an easily digestible format and written in spontaneous natural speech.
Facebook is also full of juicy gossip, which probably doesn’t hurt!
8. Sniff rosemary
The smell of the essential oil, rosemary, has been shown to improve long-term memory, mental arithmetic and prospective memory–remembering to do things at certain times.
In one study, participants who sat in a room infused with the scent of rosemary performed better on a memory task than a control group (McCready & Moss, 2013).
9. Lose weight
Like smoking, putting on weight is associated with memory problems–but these are also reversible.
Lose some of the weight and memory function is likely to return.
Petterson et al. (2013) found that older, overweight, women whose weight dropped from an average of 85kg (188 pounds) to 77kg (171 pounds), over six months, saw improved memory function.
10. Turn off the computer and sit quietly
Now that you’ve read this article, it’s time to turn off the computer, tablet or phone and sit quietly.
That’s because when we are idle, the brain is actually still performing important memory functions.
Professor Erik Fransén explains:
“The brain is made to go into a less active state, which we might think is wasteful; but [is] probably [when] memory consolidation […] takes place […].
“When we max out our active states with technology […] we remove from the brain part of the processing, and it can’t work.”
