& lt 1 & gt； Temperature: The optimal temperature for the brain is about 20 degrees Celsius. At this temperature, the brain has the strongest ability to process information and think. When the temperature is lower than 10 degrees Celsius, the brain is awake, but its ability to solve problems is poor. However, when the temperature exceeds 35 degrees, the brain energy consumption increases, people are overtired, and people are easily agitated.
& lt2> Air: When oxygen is insufficient, the brain's energy metabolism ability decreases. Its function will be reduced.
& lt3> light: In strong light environment, when brain cells are stimulated, they will feel tired, unwilling to learn and use their brains, and the utilization rate of their brains will decrease obviously.
& lt4> Color: When the brain is tired, looking at the green fields and the blue sky can make people calm and clear-headed. On the contrary, if you see scarlet and yellow at this time, your brain will be temporarily excited, but it will be suppressed and make you sleepy.
& lt5> Audio: When you are tired, you can enjoy relaxing songs for a while, so that your brain fatigue will disappear and your brain efficiency will improve.
2.9 Habit dulls the brain
& lt 1 & gt； In modern society, due to fierce competition and increasing pressure, people's brains are generally tired and lifeless. In order to keep a young and creative heart, modern people must avoid some bad living habits and pay attention to the surrounding environmental factors.
& lt2> Long-term satiety: Modern nutrition research has found that after eating too much, a substance called "fibroblast growth factor" in the brain will increase significantly. These fibroblast growth factors can increase capillary endothelial cells and fat, promote atherosclerosis, and lead to premature aging and mental retardation of the brain.
& lt3> Despise breakfast: skipping breakfast will make people's blood sugar lower than the normal supply, which will be insufficient for the nutrition supply of the brain and harmful to the brain over time. In this respect, the quality of breakfast is also closely related to intellectual development. According to research, children who eat high-protein breakfast in class generally have a relatively long thinking time, while vegetarian children's mood and energy decline relatively quickly.
& lt4> Overeating sweets: Children who eat too much sweets tend to have lower IQs. This is because children's brain development can't be separated from adequate protein and vitamins in food, and sweets can damage appetite, reduce appetite, reduce the intake of high protein and multivitamins, and lead to functional malnutrition, thus affecting brain development.
& lt5> Sleep deprivation: The main way for the brain to eliminate fatigue is sleep. Long-term lack of sleep or poor quality will only accelerate the decline of brain cells, and smart people will become confused.
& lt6> Long-term smoking: German medical scientists' research shows that long-term smoking will lead to different degrees of atrophy of brain tissue, which is prone to Alzheimer's disease. Because long-term smoking can cause cerebral arteriosclerosis, leading to insufficient blood supply to the brain, nerve cell degeneration and brain atrophy.
& lt7> Not many words: There is a special language area in the brain. Talking often can also promote the development of the brain and exercise its function. Usually say something rich in content, philosophical or logical. People who are silent and unsmiling all day are not necessarily smart.
& lt8> Sleeping with his head covered: When people sleep with his head covered, with the increase of the carbon dioxide concentration in the quilt, the oxygen concentration decreases continuously, and long-term inhalation of humid and dirty air is extremely harmful to the brain.
& lt9> is unwilling to think: thinking is the best way to exercise the brain. Only by thinking more and thinking hard can people become smarter. On the other hand, unwilling to use the brain can only accelerate the degeneration of the brain, and smart people will become stupid.
Use your brain when you are sick or ill. Persisting in studying or working is not only inefficient, but also easy to cause brain damage.
In addition, the brain is the organ that consumes the most oxygen in the whole body, consuming 500 to 600 liters of oxygen per minute on average. Only adequate oxygen supply can improve the working efficiency of the brain. Therefore, when working and studying, we must pay attention to the air hygiene of the surrounding environment.
////////First of all, brain thinking needs to consume protein's nutrition and energy, and the release of energy needs oxygen. I suggest you:
1, reasonable and sufficient nutrition, more intake of protein, sugar, phospholipids, used for brain activities.
2, keep the air fresh, often take deep breaths to ensure oxygen supply to the brain.
3. Eat more vitamins to ensure the normal metabolic reaction of the body.
Secondly, brain fatigue is related to the accumulation of "endorphins" in the brain. Proper aerobic exercise (not too intense) can accelerate the blood supply to the brain and make it decompose.
Thirdly, eye acupoint massage and eye movement with eyes closed are helpful to relax eye muscles and blood supply, and relieve eye fatigue.
First of all, you must have enough sleep. Second, you can't be hungry. It is best to do more exercise and play games properly every day.

Note: Don't eat too much. You must know that moderate exercise can enhance the blood circulation of the brain and help to keep a clear head. As for daily habits, what is said upstairs is good. Congratulations on your increasing efficiency! The simplest solution is to have a cup of coffee or eat something. If not, just tap with your fingers, or simply tap out a melody and move on! If you have a laptop or desktop computer around you, surfing the Internet and relaxing will wake you up. Ask your partner to pause or do some group activities. Talking to others can also sober you up. Indifferent, going to the toilet once an hour is also a good and effective choice. It's better to throw water on your face than to go back to the jungle full of problems. Whenever you feel tired, you should have a rest, have a cup of coffee, listen to music, stand by the window and look at the beautiful scenery. You must try it! 1, have a good rest at night
2, solve other small things around you (such as washing clothes, taking a bath, washing your hair, cleaning the house, calling others).
Don't remind yourself to stay awake at all times.
4. Drink your favorite tea

Acidic food and brain fatigue (eat more brain-nourishing food), drink tea and healthy drinks but don't drink too much water. Don't eat too much.
Some people think that they often feel tired because of lack of sleep time, excessive brain use and manual labor. In fact, many times it is the result of partial eating of acidic food.
Under normal circumstances, human blood is weakly alkaline. Whether the blood is too acidic or too alkaline, it will cause physical discomfort. As far as ordinary people are concerned, eating a lot of acidic foods every day, such as rice, noodles, meat, fish, shellfish, eggs, peanuts, seaweed, beer, sugar, etc., leads to blood acidification.
People with acidic constitution often feel tired from the beginning, cold hands and feet, easy to catch a cold, fragile skin and difficult to heal wounds. In severe cases, it will directly affect the brain and nerve function, causing memory loss, thinking ability decline and neurasthenia. Therefore, you must eat a certain amount of alkaline food every day, such as vegetables, fruits, beans, tea, coffee, milk, etc., and neutralize it with acidic food to keep your mind awake and active. Never soak in big fish and meat, because it is very acidic food.
Alkaline food
The main component of the brain is protein, and the protein of meat is acidic. Eating too much makes the brain dull and the blood circulation poor. Therefore, it is best to supplement some alkaline foods, such as fruits and vegetables, seaweed, etc., to make the pH of blood alkaline. Protein in soybean is better because it contains less acid. Fat is also important for brain nutrition, but use vegetable oil. Other alkaline fruits are oranges, oranges, oranges and lemons. Vegetables are also alkaline foods. Eating them can make the blood often alkaline and keep your head clear.
Whole brain food
Because the stool is blocked, the things left in the intestine will ferment and make the brain dizzy. Regular consumption of chlorophyll-rich vegetables such as radish leaves and cellulose-rich fruits and vegetables can prevent constipation.
Refreshing food
Make clear-headed and energetic foods relatively easy to obtain without being polluted, such as wheat, soybeans, bean powder, kelp buds, seaweed, leaves of radish and carrot, sesame oil, salad oil, natural vinegar, white sesame oil, brown sugar, oranges, lemons and honey, which can be eaten every day.
When vitamin B 1 is insufficient, it will cause nervous tissue metabolism disorder and memory decline. Therefore, vitamin B 1 is an indispensable nutrient for brain cells. Foods containing vitamin B 1 include wheat germ, mango, bitter gourd, amaranth, camellia oleifera, Toona sinensis and laver.
When vitamin C is insufficient, mental illness or mental retardation may occur. Vitamin C can refresh the mind and relieve fatigue. Foods containing vitamin C include: citrus, lemon, pineapple, grape, persimmon, radish leaves, spinach, peas and bean sprouts. //////I'm in Grade Two, but the old class always dozes off in class, so I occasionally think of many ways-seven refreshing foods.
Soybean iron is the main medium for producing human energy and is responsible for delivering oxygen to human organs and muscles. Therefore, if the human body lacks iron, it will lead to anemia and make people feel dizzy and weak. Although pig liver and lean meat are the best sources of iron, eating some red beans, black beans or soybeans often can also supplement iron, effectively improving the state of fatigue and weakness.
Spinach Spinach contains magnesium, which is a mineral that women are easy to lack. If women's daily intake of magnesium is less than 280 mg, people will feel tired. The function of magnesium in human body is to convert carbohydrates in muscle into usable energy.
Bananas Bananas are called "high-energy foods", which contain carbohydrates easily absorbed by the human body and are also rich in potassium. Potassium can help maintain the normal function of muscles and nerves in human body, but it cannot be stored in the body for a long time. After strenuous exercise, the potassium in the body will drop very low. Studies have shown that too low potassium can lead to muscle pain, arrhythmia and slow response. And eating a few bananas can supplement the deficiency of potassium.
Strawberry Strawberry is rich in vitamin C, which helps the human body absorb iron and nourish cells, so eating more strawberries can make people energetic.
Tuna Among the fish in protein, tuna is rich in tyramine, which can help the human brain to produce neurotransmitters, making people concentrate and think quickly.
Some people find that if the fiber content in breakfast is high, you won't feel hungry. Nutritionists explain that fiber can slow down digestion, continuously supply carbohydrates to blood vessels, and make the human body get energy continuously. Oatmeal is a kind of food rich in fiber, and its energy release is slow and balanced, which can keep the blood sugar level of human body at a high level all the time, so it won't feel hungry and energetic soon.
Skim yogurt Many women feel tired and sleepy before and after menstruation. A study shows that eating more foods rich in calcium, such as skim yogurt, can obviously improve this situation. If you eat three small cups of skim yogurt or two large cups of milk every day, you can relieve abdominal pain, fatigue, irritability and other symptoms, because calcium can relieve muscle tension and regulate endocrine.

Strategy 2: Medicine incense drives away fatigue.
You always feel listless and inefficient in spring, but you just don't like the refreshing tea that needs to be brewed every day. What should I do? It doesn't matter. You can make your own sachet and wear it on your body or beside your desk every day.
Recommendation for making sachets simply: Take 3 grams of Borneolum Syntheticum and Camphor, 0/5 grams of Alpinia officinarum/KLOC-and 30 grams of Cinnamomum cassia, mix and mash these four Chinese medicines, sew the cloth for making sachets into small bags, and then put them into the prepared medicine. After a period of time, if the smell in the sachet may weaken, the refreshing effect will also decrease, and it is necessary to replace it at this time.
Efficacy: The principle that the sachet can refresh is that the unique aroma of traditional Chinese medicine in the sachet acts on the brain or nasal mucosa, thus regulating the nervous system and making people refreshed. According to the research, the fragrant smell of the medicine in the sachet can stimulate the nasal mucosa and increase the content of immunoglobulin A(SlgA) secreting antibodies on the nasal mucosa. The increase of its content makes it difficult for the virus to survive on nasal mucosa and respiratory mucosa, thus greatly reducing the chance of people catching a cold.
Strategy 3: TCM self-massage
1 Massage the head and temples
Massage method: Massage the upper and lower eyelids with four fingers, then move the fingers from the corner of the eye to the temple and massage for a few minutes. When massaging, it is best to have a stable mood, chest out and abdomen in order to achieve a certain effect.
Efficacy: We are familiar with the temple. The correct position of the temple is about one-third from the brow to the ear. Touching the most sunken part with your hand is the temple. Regular massage of the temples can promote the blood circulation of the brain and relieve fatigue, and the operation is very simple, suitable for doing at any time.
Massage Yongquan point on the sole of foot
Massage method: First of all, choose the right points. Yongquan point is what we often call the foot center, which is at the bottom of our feet and the midpoint of the second metatarsal space. It is equivalent to the junction of 1/3 and 1/3 in the front of the palm. Massage time is best before going to bed every night. Massage methods include shiatsu, rubbing and so on. , about 50- 100 times each time, mainly due to foot fever.
Efficacy: This point is the starting point of kidney meridian of foot shaoyin. The kidney controls the storage of essence, has the physiological functions of absorbing, storing and sealing essence, and is in charge of the growth, development and reproduction of human body. Massage Yongquan point, through the conduction of meridians, can make the kidney have a good effect, regulate endocrine and autonomic nervous system, and refresh the mind.
Three common mistakes in refreshing the mind.
There are many incorrect refreshing methods in life, which can really restore our energy to a certain extent, but if we use these methods to drive away fatigue for a long time, what effect will it have?
1 refresh yourself with alcohol and tobacco.
There is no denying that alcohol and tobacco can refresh you. The main mechanism is to stimulate the cerebral cortex through some chemicals in tobacco and alcohol, so that the brain remains excited. It may be ok occasionally, but it is wrong to regard it as a way to eliminate troubles and fatigue for a long time. Smoking and drinking for a long time will not only bring great harm to your body, but also reduce your immunity, distract your energy and make you more prone to fatigue.
As long as you sleep more, you will feel good.
Spring is not because people sleep longer in spring, but because they can't adapt to climate change at once. People's sleep time is scientific. Adults sleep about 8- 10 hours a day. If they sleep too long, the cerebral cortex will be in a state of inhibition. I can't seem to sleep, but my mind is in a daze.
The best advice is that you get up early to exercise every day. The temperature is suitable in spring, suitable for getting up early. After getting exercise, you can get rid of some inertia, improve your immunity and feel refreshed.
Coke and coffee drinks are more effective for refreshing.
Coke coffee contains caffeine, which can refresh the mind and keep people excited, but for different people, the effect of coke coffee drinks is different, and for those who need to concentrate, it can refresh the mind. For people with complicated work, they can feel excited at first and tired after a while. In addition, women who often drink cola can also lead to osteoporosis, heart and liver diseases. It should be noted that cola coffee can't be used as a regular refreshing method///////////aerobic exercise.
Wash your face with cold water
bland diet
have many meals but little food at each
Have a good sleep+take a 45-minute lunch break////There is a good way to improve your attention and increase your concentration time after you get used to it.
However, this method will be uncomfortable to implement, and it will take a period of practice to adapt and improve.
If you give up halfway, the effect will only be a little, really only a little.
The method is:
Have you ever heard of speed reading? Speed reading websites are very popular, but that's all. After practicing basic exercises, you can still improve your concentration time and brain reaction speed. After practicing, you feel that your brain is still much better than others.
Search the internet for speed reading, and then the next article will be fine.
However, the information on the Internet is incomplete, and it can't compare with the physical book, so I won't give the link.
I suggest you go to Dangdang, spend more than 20 Mimi to buy a small notebook and practice by yourself. There are many small exercises in it.
The effect is quite quick. Pay attention to protect your eyes when practicing.
Pay attention to your concentration time at the beginning. Let's see the results of your hard exercise after two months.
