Study Finds Exercise Can Boost Memory & Fight Caffeine Withdrawal
Thinking about quitting caffeine but worried about the adverse effects? Researchers may have found a quick (and multi-beneficial) way to boost memory without caffeine. A recent study published in Nature Scientific Reports found that as little as 20 minutes of exercise can boost your memory as well as, or even better than, a cup of coffee.
How did caffeine and exercise stack up?
Researchers at the Exercise and Health Psychology Lab at Western University tested groups by first assessing the working memory of caffeine and non-caffeine consumers1. After this, participants either consumed caffeine or exercised.
Twelve hours later, their working memory was evaluated again, and they also reported caffeine withdrawal symptoms. Both exercise and caffeine improved working memory, but the exercise had the added benefit of reducing caffeine withdrawal symptoms.
But what is working memory? It helps control how we recall and store knowledge, making it an important component for day-to-day activities like reading a book or remembering what to buy at the grocery store.
In the end, this study found that a 20-minute brisk walk, which was the form of exercise used in the study, was actually better for both people who regularly consumed caffeine and people who didn't—meaning you don't have to be either a strict coffee drinker or caffeine abstainer to reap the benefits of a quick workout on your memory.
A quick workout may also help make it easier for you to quit caffeine.
Not only does this study show us that a mere 20 minutes of exercise can have serious implications for our memories, but it also shows that it's a great candidate for replacing our daily caffeine intake as it can also help diminish the negative impacts of quitting.
Other symptoms of caffeine withdrawal include fatigue (obviously), decreased contentedness, and decreased alertness. The endorphins released with exercise may help alleviate these symptoms, as they are known to improve mood.
