Have you ever imagined the benefits that a good memory can bring to you? 1. Here are four ways to improve your memory.

2. There is evidence that sleep plays a vital role in the consolidation of memories relating to learning motor skills, such as learning to play a musical instrument or ride a bike. Having a full night’s sleep soon after gaining a new skill helps consolidate the processes involved, so they can later be performed well.

It’s rewarding to continue education. Older people are often told to adopt a “use it or lose it” approach to maintaining cognitive (认知的) function. 3. In a 2016 study, US researchers found participants aged 60-90 who spent 15 hours a week for three months learning a complex skill, such as digital photography, saw significant improvements in memory tests.

Taking a break counts. 4. More than a century ago, German scientists showed that people performed almost twice as well in memory tests if they took breaks.

It’s useful to stay social. Having an active social life delays memory loss as we age, US scientists who asked people in their 50s and 60s to do memory tests every other year between 2001 and 2007 found the decline in recall abilities of their most sociable subjects to be half that of the least well connected. 5.

A. Sleeping well helps strengthen memories.

B. Old people should participate in easy activities

C. Yoga, meditation or other relaxation techniques may help.

D. Memories can be destroyed if the brain doesn’t have enough rests to sharpen them.

E. In fact, when it comes to memory, research suggests that only certain types of mental activities help.

F. Being able to remember important pieces of information can give you a powerful advantage in your life.

G. Having good friends, volunteering for charities and other forms of social engagement also protect memory.
