According to a new study by Western and British Columbia Universities, when it comes to your working memory, a quick 20-minute walk is just as effective and a healthier alternative to a cup of coffee.
The new study was published in December 2019 in the Nature Scientific Reports, it says that brisk walking on a treadmill for about 20 minutes improves the focus of your brain and the alertness just as much as a cup of coffee would.
The study was done on 59 participants from ages 18-40. Thirty of these participants drank coffee regularly and 29 didn’t drink coffee at all. They were tested under three conditions; after a 20-minute brisk walk on a treadmill or a slow jog and after drinking coffee (an average cup in powdered form) and again with neither of these interventions – to be used as a baseline. These participants were then tested to see how quickly they could process and recall information.
The results showed that both brisk walking/jogging and caffeine increases the accuracy of the participants’ tests and that they improved by 20% after exercising or drinking a cup of coffee. However, exercise ensured that the regular coffee drinker didn’t experience a caffeine crash after a few hours of drinking coffee.
Exercise decreases symptoms like fatigue, sluggishness, and lack of concentration. The withdrawal symptoms of coffee becomes worse the more regularly you drink it.
