What is the most brain tonic before college entrance examination? How to decompress the examinee bef

The 2018 college entrance examination is approaching, and the candidates and their parents are in a tense state of "preparation". Because of the mental pressure before the examination, many examinees will have the problem of brain fatigue. Many parents think it's because of excessive use of brain, so what is the most brain tonic before college entrance examination? How to reduce pressure before college entrance examination?

The first is decompression

"The first thing to do is to decompress the examinees properly!" said Professor Ji Chengye, director of the Institute of child and adolescent health of Peking University. He said: 'stress has a very close relationship with memory. It is suggested that parents should not always talk about scores, rankings, future and other topics in front of their children. At home, they can talk more about interesting things in life, and appropriately relieve the pressure of examinees. '

"Second, we should ensure the quality of sleep and sufficient sleep time. After a good rest, the brain can work more effectively. Listening to a soothing music before going to bed, making the room darker, making the bed more comfortable, eating less spicy and stimulating food before going to bed, and not eating too full are all good ways to help sleep. '

'again, don't overdo it. The more tired the brain, the less sensitive it will be and the less efficient it will be. Parents can remind examinees to take a walk, do exercises, listen to music, work and rest, and let their brains rest. '

What nutrition does brain need most before examination

Professor Ji suggested that we should follow the principle of "reasonable diet and balanced nutrition": first, blood sugar is the direct energy source of the brain, to ensure the blood sugar supply of the brain, so as to maintain the excitement of the brain. Therefore, children should be given enough staple food every day. And one third of the staple food should be coarse grain to ensure the slow and continuous rise of blood sugar. Secondly, enough protein is needed. Protein is the basis of all cells. Glutamate can also play an active role in brain cells. Protein rich foods include meat, eggs, milk, soybeans and soy products. Third, the right amount of fat can help the brain improve memory. You can eat some fatty fish, such as salmon, oily nuts (walnuts, etc.). Fourth, fresh fruits and vegetables to supplement vitamins and minerals.

"Delicacies" tonic can cause brain dullness

Ji Chengye also reminds the parents of the majority of candidates not to blindly supplement the "delicacies". On the one hand, if the diet changes greatly before the exam, the examinee's intestines and stomach will not absorb these foods well, and diarrhea and anorexia will occur; on the other hand, eating too miscellaneous, full and greasy will increase the burden on the intestines and stomach. This will increase the blood supply of the gastrointestinal tract, and reduce the blood flow to the brain, resulting in the lack of energy supply to the brain, resulting in brain dullness and not quick thinking.

If parents don't think it's safe to give their children supplements, Liu Lan, a teacher from Beijing nutritionists Association, also suggests that they can properly supplement the examinees with phosphatidylserine, DHA, B vitamins and other nutrients. These nutrients can improve memory and brain.
