It consumes a lot when studying, and it doesn't consume physical strength to stay at home. When you are studying, you want to do something that has nothing to do with your study. This is psychological suggestion. At home, I will eat snacks and replenish energy at any time. And you don't have this option in class. First of all, we consume energy when studying. First of all, we should make it clear that studying and staying at home are not at the same level in energy consumption. On the surface, when we study, our bodies don't move, as if we don't consume physical strength. We just write and write, but we are thinking. ⊙! On the surface, exercise consumes a lot of physical strength, but in fact, the brain has the greatest ability to consume organs, accounting for one-fifth of energy consumption. When we are learning to think, the brain is equivalent to a working computer and needs to consume energy. The more detailed the work, the more energy consumption needs to be considered.
At home, of course, we don't think too profound questions, but more often we relax, play mobile phones and read novels. The brain is in a state of not thinking, and there is no need to think, so the brain just works normally, just like the power consumption of computers connected to the internet and not connected to the internet is very different. We don't consume much energy at home and don't feel too hungry.
I have a deep understanding of learning the concept of energy consumption. I stayed up until 4 o'clock that day and got up at 6 o'clock. Because of the background of young people, I can still walk around and chat. But when I look at these questions in the math exam at night, I can survive the previous multiple-choice questions, and I will burst into tears in the following math questions. I have a splitting headache and can't think at all. It was at this time that I deeply realized that I still needed a good rest.
When the college entrance examination approaches, there is a brand similar to "Powerful God" to advertise. At that time, many parents of students would prepare these energy-supplementing drugs, so my mother bought these things for me. I don't know if it's a psychological effect, but I really feel my energy has improved. In fact, this is a supplement to my main ability. In high school, I studied hard, thought hard, studied math problems and recited a lot every morning. We consume a lot of energy. Therefore, even if the body does not move, our brain consumes a lot of energy when working, so it is easy to get hungry when studying.
Second, when studying, I like to pay attention to things that have nothing to do with learning. Secondly, we students easily have a problem. Because we are required to study, people with low self-control are easily distracted. For example, "Show a movie in this class" will make me jump for joy, surprise gift. Because I have been studying for too long, I want to do something else, that is, "you are interested in something that has nothing to do with my study." Three meals a day is necessary for the human body. The pleasure brought by delicious food and the temptation of not studying make it easy for me to think in a class before lunch and dinner. What shall I eat later?
And this kind of timed thinking gives a psychological hint that it is time to eat, and we are hungry. The behavior of buying snacks between classes is the embodiment of the above psychological suggestion. I wasn't very hungry at first, but everyone went to buy snacks. They thought that getting up at 6 am, reading early+two classes+broadcasting gymnastics, the food for breakfast had already been exhausted. We need energy to replenish it. Under the cluster effect, I will also go shopping with the crowd.
Therefore, we may not be really hungry, but under the influence of psychological suggestion and cluster effect, we think we are hungry, so we always feel that we are easily "hungry".
Thirdly, when we stay at home, we may eat snacks. Finally, we stay at home and get hungry less easily. There is a more likely reason. Besides three meals a day, we also eat snacks, especially when playing mobile phones. In class, we have no choice. We are not allowed to eat in class.
Stay at home with snacks to supplement, eat if you want, and your physical strength and energy consumption are not great; When studying, you have no right to eat or drink at any time. Thinking consumes a lot of energy, and supplementing less consumes a lot. By contrast, you are definitely more likely to get hungry when you are studying.
We consume a lot of energy when studying. When we concentrate on our studies, we should not forget to replenish energy, so that we can think and remember with a healthy body and let our brains work in a good environment. Therefore, it is necessary to ensure three meals a day and a healthy and regular diet.
