1 . Improving memory is important to success in studying. But is there anything that we can do about it? One solution might be walking backwards.

According to a new study published in the Journal of Cognition, walking backwards, whether doing it really or just imagining it can improve the brainpower in the short term. In the study, 114 volunteers were asked to watch a video in which a woman had her bag stolen. Then they answered 20 questions about the information shown in the video. Ten minutes after watching the video, the volunteers were divided into three groups. The first two groups were told to move forwards or backwards 10 meters while the third group was asked to stay still on the same point. The researchers found that the backwards walking group got two more correct answers on average than the other two groups. This suggests that a relationship between the concepts of time and space is important to the way our minds form memories,

When we walk backwards, everything we learn becomes strange to us. “This forces the brain to think in a different way,” US scientist Christine Weber told Forbes. It almost always means that our brain needs to be more active in the limited time. Naturally, our short-term memory will be improved greatly.

Besides improving our memory, walking backwards also plays an important role in physical health, especially fitness. Another study found that walking backwards puts less strain (压力) and requires a smaller range of movements from the knee joints (膝关节). Thus, there’s less pressure and pain in the knees.

In addition, walking backwards, compared to walking forwards, is more challenging. It requires you to use muscles and movements that you probably seldom use, making it a prefect way to change your exercise routine for greater fitness gains. Meanwhile, by making people put in extra effort, it naturally bums more fat and calories.
