We write mirror words from right to left with our left hand, that is, we set up a mirror on the left or turn the paper to the other side, and look at the light and we will see the orthography. Personally, I guess this may be the most effective way to promote communication between the left and right brain, or it may be the real use of the right brain.

It is generally believed that the main function of the left hemisphere is logical reasoning and language expression, which is related to language, numbers, concepts and analysis. The main function of the right hemisphere is spatial and image thinking, which is embodied in music, rhythm, painting, intuition, sense of space, integrity, imagination and comprehensive power.

In other words, writing with the left hand can exercise the above abilities, in fact, it mainly promotes the operation of the right brain and enhances its thinking ability. Exercise the right brain. If you use your left hand more often, you can improve your image memory ability.

It is also because the left hemisphere of the human brain plays a leading role in language, writing, calculation, thinking and judgment, while the right hemisphere plays a leading role in skills, art, music, emotion, admiration and aesthetics. For people who are used to right-handed sports, a lot of information will be continuously transmitted to the relevant nerve centers of the left hemisphere, which will promote and strengthen the functional development of the left hemisphere, so people often call this hemisphere the "dominant hemisphere"; The right hemisphere with relatively little information is called the "lower hemisphere". On the contrary, people who are used to exercising and working with their left hand will further develop the function of the right hemisphere. Of course, not all the information received by the human body is obtained from the left hand or the right hand, but many are transmitted to the brain through other sensory organs.

The following behaviors are all ways to exercise your left hand:

1. Eat with your left hand. The dining habit of China people is different from that of westerners. Someone once proudly listed it as one of the reasons why China people can get good results in world-class intelligence competitions. However, we should also see that compared with the "left-right attack" of westerners using knives and forks, we have lost one of the most common opportunities to balance our right and left hands. Therefore, it is suggested to gradually exercise your left hand with a spoon and eat with chopsticks.

Brush your teeth with your left hand. This is also an excellent opportunity to exercise the left hand and activate the right brain. When you start brushing your teeth with your left hand, you must do it lightly. Too much action can easily damage your gums and make you lose interest and confidence in exercising your left hand to brush your teeth. Even when you can brush your teeth skillfully with your left hand, you will find a very interesting phenomenon: your right hand will always make a very hard action, or it will be stiff at a certain angle, so it is difficult to brush your teeth with your right hand as relaxed and natural as your left hand.

3. Use scissors for your left hand. Because most of us are right-handed, the scissors we can usually see are "right-handed scissors", that is, to correspond to the adduction function of the thumb, we put the right-handed scissors on it. Because the "left-handed scissors" can't be found for the time being, when using conventional scissors for the left hand, only the left thumb plus downward force can achieve the purpose of paper-cutting and line-cutting.

Use the mouse with your left hand. With the improvement of living standards and the increasing popularity of computers, we can hardly go to work without computers. I suggest you exercise your left hand and use the mouse. First, observe whether your mouse is symmetrical. Because there are many left-handers abroad, the mouse products of international brands such as IBM, Microsoft and Logitech are mostly symmetrical. In the Windows operating system, the mouse option of the control panel can change the left and right keys, thus becoming a left-handed mouse. Exercising the left-handed mouse has at least two advantages: 1. Reduce carpal tunnel syndrome caused by long-term mouse use; 2. Extend the service life of the mouse by at least 50% (I once threw it away because the left mouse button didn't work. What a pity to think about it now! )。

5. Write with your left hand. When watching foreign movies and listening to foreign teachers' lectures, foreigners can often be found signing, writing and writing on the blackboard with their left hands. We should also practice. Writing with left hand can be divided into two aspects. On the one hand, we write from left to right with our left hand, that is, we try to replace the function of our right hand with our left hand. Although it was ugly at first, it may not be as beautiful as when I first learned to write with my right hand. On the other hand, we write mirror words from right to left with our left hand, that is, we set up a mirror on the left or turn the paper to the other side, and look at the light and see the orthography. Personally, I guess this may be the most effective way to promote communication between the left and right brain, or it may be the real use of the right brain. When you calm down and write the mirror image easily, you will be surprised why there is such an interesting phenomenon.

6. Mobilize the left hand and left limb to participate in sports activities. You can practice shooting with your left hand, shooting with your left hand, playing badminton and table tennis with your left hand, and kicking with your left foot. Finally, practice throwing things with your left hand and carry out coordinated training with your whole body.

7. Turn the fitness ball with your left hand. Don't think that turning two fitness balls by hand is the patent of Shanghai tycoons in the old society or the elderly today. We can use it to exercise our left hand. If the fitness ball is too heavy to carry around, you can replace it with two suitable walnuts, and the edges and corners on the walnuts may get better stimulation effect.

8. Turn the pen. It is often seen that someone turns the pen in his hand, which is dazzling. Although I personally disapprove of this behavior, if you have a soft spot for turning pens, I suggest you start practicing with your left hand again, although I find it annoying to drop the pen on the ground.

9. Start with the functional orientation of the right brain. Russian medical experts used music to treat premature babies and mentally retarded children, and achieved remarkable results. Americans find that listening to background music can significantly improve their memory. According to a survey, more than 90% of the executives in the US Congress and Fortune 500 companies have received music education since childhood. Because the right brain is related to music, rhythm, painting, intuition, sense of space, wholeness, imagination and synthesis, it may also be a good way to develop the right brain by listening to music, touching painting and imagining more.
