How to improve your memory?

It’s generally accepted that you can’t teach an old dog new tricks, but when it comes to the brain, scientists have discovered this old saying simply isn’t true. 1. Whether you’re looking to sharpen your mind, boost your mental performance, or preserve your memory as you age, these tips can help.

2. Memory, like muscular strength, requires you to “use it or lose it”. The more you work out your brain, the better you’ll be able to process and remember information. The best brain exercises break your routine and challenge you to use and develop new brain pathways.

Don’t skip the physical exercise. While mental exercise is important for brain health, that doesn’t mean you never need to break a sweat. Physical exercise helps your brain stay sharp. 3.

Get enough sleep. There is a big difference between the amount of sleep you can get and the amount you need to function at your best. The truth is that over 95% of adults need 7.5 to 9 hours of sleep every night. 4. Memory, creativity, problem-solving abilities, and critical thinking skills are all harmed.

Make time for friends. When you think of ways to improve memory, do you think of “serious” activities such as mastering chess strategies, or is it more relaxing pastimes—hanging out with friends or enjoying a funny movie? 5. But countless studies show that a life full of friends and fun comes with brain benefits.

A.Keep stress in check.
B.Give your brain a workout.
C.If you’re like most of us, it’s probably the former.
D.Even losing a few hours of sleep makes a difference!
E.In fact, interacting with others may provide the best kind of brain exercise.
F.The human brain has an astonishing ability to adapt and change, even into old age.
G.It increases oxygen to your brain and reduces the risk for disorders that lead to memory loss.

y = sin x, x∈R, y∈[–1,1],周期为2π,函数图像以 x = (π/2) + kπ 为对称轴
y = arcsin x, x∈[–1,1], y∈[–π/2,π/2]
sin x = 0 ←→ arcsin x = 0
sin x = 1/2 ←→ arcsin x = π/6
sin x = √2/2 ←→ arcsin x = π/4
sin x = 1 ←→ arcsin x = π/2
