5 Easy Memory Tricks

You know that eating healthy, staying active and solving a few brain games can help keep you sharp. But these lesser-known habits work wonders too.

5 Easy Memory Tricks

1. Sit tall

When we are sad or afraid, we naturally collapse or cower. Studies show that the converse is also true: When we slouch, this defeated position actually causes us to feel anxious or depressed—which makes it harder to think clearly and remember things. In a study of 125 college students, 56 per cent found it easier to do math problems when they sat up straight than when they slumped down. Erect posture apparently improves memory because it boosts blood and oxygen flow to the brain—by up to 40 per cent, according to one estimate. 

2. Exercise—once

Having trouble remembering faces? Break a sweat. In a small study, researchers at the University of Iowa, USA, showed pictures of faces to older folks (average age: 67) on two different days and after two different kinds of workouts. On one day, they pedalled a stationary bike for 20 minutes at a pace that was intense enough to make them breathe heavily but still be able to talk. On the other day, they simply sat for 20 minutes on a self-pedalling bike. On average, people remembered the faces better after the intense exercise. What’s more, the memory gains after a single workout were similar to the gains after three months of regular exercise.

3. Limit TV

Every parent and grandparent has heard that too much screen time can hurt a child’s cognitive development. But what about those at the other end of their lifespan? To find out, researchers at University College London, UK, analyzed data from more than 3,500 participants, who were age 50 or older and did not have dementia at their initial assessment, in a long-term study. Controlling for physical activity, health conditions and demographic factors such as education, they found that people who watched more than three and a half hours of TV a day for six years experienced a greater drop in verbal memory test scores (an average decrease of 8–10 per cent) than those who watched less (an average decrease of 4–5 per cent). On a related note: Another study found that watching violent programming elevates stress hormones, which impairs memory.

4. Doodle

Researchers at the University of Waterloo, Canada, recruited a group of younger adults and a group of older adults, gave them a series of 30 words and asked them to either draw or write them out. After a short break, both groups were asked to recall as many words as they could. In both age groups, those who drew the words remembered the most. The effect was actually greater in the older adults. According to one of the study’s authors, this happens because while some parts of the brain involved in memory retrieval deteriorate with age, the visual-processing regions usually don’t. Hence, sketching can help adults of any age keep their memory sharp.

5. Walk backwards

Next time you’re trying to recall something, don’t just think back—walk back. In a series of experiments, participants viewed a video of a staged crime, a word list or a set of pictures. Then they imagined walking forwards or backwards, watched a video that simulated forwards or backwards motion or actually walked forwards or backwards. Some people also sat still. Backwards motion—whether real, imagined or watched—helped people remember the information better than sitting still and, in most instances, better than forwards motion. It may be that moving backwards in space mentally helps us move back in time to the moment we learnt something.
