Why do I have a headache when I do 6 or 7 hours of questions in a row?

The memory and thinking of the human brain are the most energy-consuming of the human body, which is why mental workers earn more than manual workers. Because on the surface, although manual workers are tired and tired, and mental workers seem to be more relaxed, in fact, mental workers consume much more energy than manual workers.

You are due to the long-term use of the brain, resulting in a large amount of nutrients in the body being consumed by the brain, and the brain is inevitably damaged in the process of thinking, but the nutrients in the body are used to support the brain to think about problems, and the damage to the brain is not well repaired. Then you get a dull pain in your head. At this time, it is often good to rest and rest, because the brain is well repaired in the process of resting.

Therefore, the combination of work and rest will make you healthy, and proper rest can make you smarter.

It's not about psychology, and it's not about air conditioning. I would do the same.

Do you think, if you do the questions for a long time in winter, will your head heat up? It's a truth. Overusing the brain is sure to produce some reactions.

It is recommended that you do not do the questions for such a long time. At least you have to take a break from eating or something, and then there's the cliché of exercising. Every morning jog and the like have the effect of coordinating the body.

Relax properly, sit all the time and concentrate so much, it is normal to be tired, and it will have some effect.

If you are overtired, you should take a break. The combination of work and rest will be even better!

Apply a hot towel to your forehead.

Try to rest as much as possible, but it's not about how long you study.

It is not to seize every minute to study, but to seize every minute of the debate brigade to learn.

It's a common phenomenon to sleep a little less on average It is best to spend more than 8 hours a day Pay more attention to nutrition Learning is a thing that needs to be persistent Come on Oh If you have a headache staring at the scum, Jian Pei will sleep more o ( Kai Zhi quietly )o

Pretty much the same, when I was in my third year of high school, I also had a lot of insomnia, I used my brain too much, and I bought a bottle of vitamin phosphorus tonic juice to drink, and the things were not expensive.

There are several main reasons for this:

Exposed to computer screens for long periods of time.

Sitting in front of the computer and not moving much, the pressure on the spine and cervical spine is high for a long time, and the nerves in the cervical spine and head are compressed.

Playing with the computer, the mind will be highly concentrated, which is easy to cause excessive brain use and brain fatigue.

You can try the following methods to solve the problem:

1.Place a mini cactus or cactus near your computer to absorb radiation.

2.Get enough sleep, get away from your computer at intervals, and relax.

3.Apply eye drops to give your eyes a break.

Surveys have shown that the proportion of visual fatigue in the latter is 4 6 times higher than that of the former when reading and operating the computer for the same time. Accelerated evaporation of eye fluid when looking at the computer People blink unconsciously 15 25 times per minute under normal conditions, but when looking at the computer, due to the easy to concentrate on staring at the screen, this physiological blink will be reduced to 5 10 times, plus when looking at the computer, the eyelids open to increase the exposed area of the cornea, the evaporation of tears is accelerated, and it is easy to appear dry on the ocular surface and corneal damage, and there are symptoms such as dry eyes, foreign body sensation, photophobia, and tearing. According to a domestic survey, 3% of people have corneal punctate staining before using a computer, and it reaches after 2 to 4 hours of using a computer.

When corneal damage is severe, corneal epithelial erosion and inflammation may occur.

Ordinary people don't think there is much difference between headache and headache, your teacher's idea should be that a headache means that you are very troubled by something, such as: I have a special headache with mathematics, and a headache indicates a physiological form, which is a real headache. I hope to have some cooperation with the landlord.

When it is said that headache does not refer to the headache in the real sense, but mostly to say that the headache is caused by something that causes trouble, and the headache usually refers to the pathological headache in the real sense.

Pain is external, pain is internal, in fact, it is also a meaning, but Mandarin has made them change the meaning, I only said headache, I didn't write it, I wrote about headache, I didn't say headache

There is no difference, it's just that the group habits are called differently. Both headaches and headaches can indicate objective discomfort, pain. But headaches are also commonly used to indicate a condition that is a headache.

Brain tumor headache manifestations: Brain tumor patients usually have headache manifestations, and headache is a dull pain, which gradually decreases with the development of the disease, and the pain time will become longer and longer.

After using the computer for about half an hour, close your eyes for five seconds, and then look up at the window in the distance for about ten seconds.

Prepare a cooling oil on your body, and rub a little on your temples when you have a headache.

Use sparingly and preferably with an orange or two next to your computer.

Headaches are associated with overuse of the eyes.

Every once in a while, take a break, especially to rest your eyes (close your eyes and roll your eyes).

The light on the display should not be too bright or too bright.

The easiest and most effective way to do this is to take a walk outside.

Try not to stay at the computer all the time, and take a break from work to see the green scenery in the distance.

Headaches caused by using the brain for too long are mainly as follows: 1Radiated by a computer screen for a long time 2Lack of sleep, coupled with prolonged and sustained concentration in front of the computer 3

Eye strain, along with headaches. For several reasons, you can try the following methods,1Place a mini cactus or cactus near your computer and the plant will absorb radiation 2

Get some sleep, get away from your computer at intervals, and relax 3Apply eye drops to give your eyes a break. I hope it can be helpful to you, thank you for adopting

One reason is eye fatigue, looking at the computer for a long time and the interval between blinks becomes longer, resulting in eye fatigue, so it is best to stand up and look at the distance, do eye exercises, blink more, and drop some eye drops if you are really tired, but use less and pay attention to the shelf life of only one month.

Another reason is that sitting in front of the computer does not move much, the pressure on the spine and cervical spine is high for a long time, compressing the nerves of the cervical spine to the head, stand up and stretch the limbs, and move the neck, you can buy a small fitness hammer, knock on the shoulders and cervical spine, pinch it with your hands, you have to use force, **soreness pinch**.

All of the above is my experience.

See more greenery and rest more.

The computer is much more comfortable when the light is dimmed.

It's helpful to do a lot of reading.

Speed and accuracy are not guaranteed, but the feel is definitely possible, and it is not realistic to do six articles a day, because it is difficult to stick to it for more than a month.

Therefore, it is recommended to have a set of real questions a day, and then add materials to the weak links in the four aspects of listening, speaking, reading and writing, and repeat the real questions, and brush it twice before the test.

You don't have to look at the reference book to analyze the wrong topic, think about it yourself, bring it to the original text, and take a look at it myself, when I do it, I often get into the horns, so when I do it, don't think about the topic too complicated.

You can't do reading blindly, you can ask the teacher how to do each type of question and how to determine which of the three to do first.

When you do it, you must finish it in one breath, and control it in 18-19 minutes, if you can do it consistently.

A score of 8 is also possible.

Hope it helps!

Take a walk for an hour a day and drink liters of water.

Headache is the problem of overuse of the eyes, and the eye headache will be relieved by resting.

If you watch it every day, but it is not long, 2-5 hours will not cause headaches.

If you look at it every day, your eyes will hurt for 5-10 hours a day.

Your situation is often caused by lumbar spine disease and strain. In this case, an X-ray examination is done. Pants can generally use traditional Chinese medicine, anti-acacia inflammation and analgesic drugs, physiotherapy, external drugs, etc. Don't get tired.

After walking for 2 minutes from home to school, he switched to 60 meters and arrived five minutes early. How far is Xiaomin's home school?

Let's say he walked for x minutes.

50x（x+8)=60x(x-5)+2x50

50x+400 =60x-200

x = 6050x (60 + 8) = 3400 meters.

In one tree-planting activity, both groups planted the same total of more than 100 trees. The number of people in the two groups varied, one group planted 5 trees and the rest planted 13 trees, and the second group planted 4 trees and the remaining 10 trees. How many people are in the two groups?

According to the title, the number of trees planted in each group is divided by 13 and 5; Divide by 10 to 4;

The problem of the Chinese remainder theorem...

Arithmetic: The smallest number that is divisible by 13 and divided by 10 to remainder 4 is: 13 8 = 104

The smallest number that is divisible by 10 and divided by 13 and remainder 5 is: 10 7 = 70

Satisfy divide by 13 and remainder 5; Divide by 10 to 4; And if it is more than 100, it is 174

There were 174 trees in two shifts.

One group has: (174-5) 13+1=14 people.

The second group has: (174-4) 10+1=18 people.

Two groups in total: 14 + 18 = 32 people.

Algebraic solution: set a group of x people and two groups of y people; x and y are positive integers.

100<5+13(x-1)<200

100<4+10(y-1)<200

100<13x-8<200

100<10y-6<200

108<13x<208

106<10y<206

9≤x≤17

11≤x≤20

5+13(x-1)=4+10(y-1)

13x-8=10y-6

y=(13x-2)/10

y is an integer, then the single digit of 13x is 2

The single digit of x is 4

The number of requirements met is x=14

y=(13×14-2）/10=18

Two groups in total: 14 + 18 = 32 people.

1. A pasture is overgrown with grass, and the grass grows evenly every day. This pasture can feed 10 cows for 20 days and 15 cows for 10 days. Q: How many days can it feed 25 cows?

10 times 20-15 times 10) divided by (20-10) = 5 (parts).

10 times 20 - 20 times 5 = 100 (parts).

100 divided by (25-5) = 5 (days).

40 5+4=12 units.

3.Container A has 150 grams of brine with a concentration of 4%, and container B has a certain concentration of saline, take out 450 grams of brine from B and mix it into a concentration of brine, find the concentration of B?

The mass of salt in the mixed container = (150 + 450)*

It turns out that the mass of salt in container A = 150 * 4% = 6g

Then the quality of the salt in container B =

Then the concentration of brine in container B =
