  1. Let's look at the difference between the concepts of “brain fatigue” and “fatigue”.�

    Brain fatigue is a syndrome, a disease that is characterized by serious symptoms:pain in the head and neck, pressure sensations, blurred vision, rapid heartbeat. All these signs are a reason to see a doctor.�

    If you are simply tired of making decisions, can't concentrate on one task for a long time and do your job as well as before, then this is fatigue.

    Reasons. Fatigue occurs due to severe overexertion, when physical resources are depleted, fatigue accumulates, there is no diet, rest and sleep, etc. As a result, our attention can not be kept on the current task, we become distracted, constantly distracted from work by external stimuli. As a result, overall performance decreases.

    How can I fix this? It is easier not to allow this. So that the “eye does not get blurry”, you need to take breaks from work.�

    Moreover, there is already a proven technique, which is almost 30 years old. This is the Pomodoro technique, and it was invented by Francesco Cirillo. It is so called because the kitchen timer used by the Italian student looked like a tomato. It is the timer (any) that will be your main tool. When you start working, clearly define your task and set a timer for 25 minutes. At this time, do not be distracted by gadgets, colleagues and any external stimuli, completely immerse yourself in your work. As soon as the timer rings, take a break for 5 minutes – don't think about what you were doing just now, don't think about the upcoming tasks, just get distracted. This half-hour (25 minutes of work and 5 minutes of rest) – and there is one “tomato”. After four such “tomatoes”, take one long break – from 15 minutes to half an hour.

    Another plus. This technique will not only help you avoid fatigue, but also train you to switch your attention. Attention is one of the main cognitive functions of the brain, and the rest — memory and thinking — depend on it, but it also works in the opposite direction. The overall performance of the brain depends on the state of all cognitive functions. Therefore, attention problems may also occur due to poor performance of other functions.�

    In order for the brain to be in good shape, it needs to be constantly trained. Cognitive simulators are suitable for this purpose. They are aimed precisely at training attention, memory and thinking. The Russian online service Wikium offers to check how your brain functions work. Based on the test results, you get an individual training program. When registering on the site, you indicate what skills you would like to develop, pass the test, and then you can immediately start training. A smart algorithm monitors your progress by itself and complicates the development program so that your brain works more efficiently.

  2. Apparently, Olga Turkina confused the phrase “number of neurons” and “number of neurotransmitters”. The number of neurons does not decrease depending on fatigue during the day, of course, but a certain number still die every day. So does some of the progenitor cells in the dentate gyrus of the hippocampus. And when the brain gets tired, some neurotransmitters actually become less, some-too much. And in the process of learning and accumulating new memories, the size and efficiency of synapses changes. Since this cannot happen indefinitely, the brain needs sleep to preserve some of the synaptic changes and filter out some of them. This is the main reason for the existence of sleep as a phenomenon, if we follow the theory of synaptic homeostasis accepted by many scientists. But specific fatigue occurs when, in the process of chemical reactions inside synapses, too much adenosine left over from the ATP used sits on the inhibitory receptors on neurons and inhibits the transmission of nerve impulses.

  3. The functional unit of the brain is neurons. There is such a property as neuronal fatigue, which is associated with the fact that the supply of neurotransmitters is depleted. These substances are involved in the transmission of information from one neuron to another. When you perform monotonous work for a long time, the number of neurons decreases and therefore the person gets tired, becomes less attentive.

    You should always take breaks to rest and allow your mediators to recover. During the working day, you should take breaks for at least 15 minutes. If you are engaged in mental activity, it is better to engage in physical activity. It is true that recreation consists of changing activities.

  4. Lie down to sleep and everything will pass, during sleep, information is laid out on the shelves, excess junk is forgotten (or rather archived and hidden in the far corners of memory, because in fact nothing is forgotten). It is necessary to rest, but it should be remembered that the brain exposed to intellectual loads develops, and the brain that is not loaded with work degrades.

  5. Because the supply of substances for information exchange in brain cells is limited.Because the cells accumulate substances used for their work.

    Toxins can also interfere with productive work,and toxins are substances that block the entrance to the passage of a certain type of substance (mediator)from one cell to another

  6. The law of conservation of �energy. If you are tired, then your energy is exhausted. If you ask such a question, I will probably ask you a counter question: “Why can your legs get tired, but your brain shouldn't?

  7. In our head – an abundant number of neurons and nerve fibers that coordinate work and function. Between neurons are synapses (connections). In these compounds, mediators are released from some cells and act on others. Mediators are substances that cause changes in the charge on the membrane, which contributes to the transmission of impulses in the head.�

    But these mediators tend to be depleted, which leads to cell fatigue, and as a result, to our fatigue. Therefore, it is important that all cells function simultaneously, and all work is distributed evenly. Therefore, a healthy lifestyle is important.�

    Emotions can affect the functioning of these synapses. Joy – short-term signaling. Sadness can be prolonged. It is important not to let a bad mood “take over” you, it also depletes your reserves!

    From overexertion treats “Glycine”. It is an inhibitory neurotransmitter, which slows down the effect of exhaustion.�
