To improve your memory, focus on two things: the habits that keep your brain working well, and the techniques that help information stick. Sleep, exercise, and cutting distraction matter more than any brain game. On top of that, encoding tricks like chunking and the memory palace lock in what you’re trying to learn. Here’s what the evidence supports.
Start with the habits, not the hacks
People reach for memory apps first, but the biggest levers are unglamorous.
Sleep. Memory consolidates during sleep, especially deep and REM stages. Skip sleep and today’s learning barely sticks. This is the single most cost-effective thing you can do, and the research is not subtle about it.
Exercise. Regular aerobic activity is one of the best-supported ways to protect and even improve memory across your life. It boosts blood flow and growth factors the brain uses to form connections. You don’t need a gym; brisk walking counts.
Cut distraction. Most “memory failures” are really attention failures. You didn’t forget where you put your keys; you never encoded it because you were on your phone. Full attention at the moment of learning does more than any trick applied later.
Manage stress. Chronic stress hormones interfere with the brain regions that form memories. Whatever lowers your baseline stress, exercise, sleep, social contact, pays off in recall.
Then add encoding techniques
Once the foundation is solid, techniques multiply your results:
- Chunking: group information into small units. Test it on the number memory test.
- Spaced repetition: review at growing intervals to beat the forgetting curve Hermann Ebbinghaus mapped in the 1880s. Best for facts you need long-term.
- The memory palace: place items along a familiar route. The most powerful method for lists and speeches. See the method of loci.
- Elaboration: connect new information to what you already know. More hooks, better recall.

What doesn’t work as advertised
Brain-training games improve the game you play, but the promised transfer to general memory or intelligence is weak in careful studies. Play them because they’re fun, not because they’ll make you smarter.
Supplements rarely deliver. A few, like treating a genuine B12 deficiency, help if you’re actually deficient. Most “memory pills” have thin or no evidence. Save your money.
Passive rereading feels productive but is one of the weakest study methods. Testing yourself, retrieval practice, beats rereading by a wide margin.
Measure your progress
Improvement is easier to sustain when you can see it. Take a memory test as a baseline, apply these methods for a few weeks, then retest. The working memory test is a good one to start with, and the average memory score page shows what a typical result looks like. To understand the systems you’re training, read how memory works.
Frequently asked questions
What is the fastest way to improve memory?
For an immediate boost, chunk information and remove distractions when you’re trying to remember something. For lasting improvement, prioritize sleep and regular exercise. There’s no instant fix for raw capacity, but better attention and encoding produce noticeable gains within days, and habit changes build over weeks.
Do brain-training apps improve memory?
They improve performance on the specific games, but the claim that this transfers to everyday memory or intelligence is weakly supported. Careful studies find little general benefit. Enjoy them as entertainment, but don’t expect them to outperform sleep, exercise, and real encoding techniques for actual memory improvement.
Can you improve memory at any age?
Yes. The brain stays adaptable throughout life, and sleep, exercise, mental engagement, and encoding techniques help older adults as well as younger ones. Some age-related slowing is normal, but it doesn’t stop you from learning new skills or improving how you remember. It’s never too late to start.
How long does it take to improve your memory?
Attention and encoding tricks help immediately. Habit-based gains from sleep, exercise, and reduced stress build over a few weeks to months. Techniques like the memory palace take a few sessions to feel natural, then keep paying off. Consistency over weeks beats any single intense effort.
