Why do you always sit at work and feel tired?

Many people feel that they have run out of energy after work every day. Even if they work sitting down, they are very tired. Sometimes I feel more tired than manual labor, but I will still be exhausted. Why? What should I do if I feel very tired at work? Let me introduce it to you.

The fatigue we usually say is actually divided into two types, one is mental fatigue and the other is physical fatigue.

Mentally speaking, do you feel groggy when you go to work every day? After work, you feel that your mind has been emptied and you can have a good rest.

When people think, millions of neurons in the brain will transmit information to each other and transmit the instructions of the brain to all parts of the body. These neurons also need "fuel" when working. It is estimated that they consume 75% of blood stored in the liver every day, and their oxygen consumption accounts for 20% of the whole body's oxygen consumption. Neurons consume energy in a unique way. First, astrocytes near the wall of large capillaries absorb energy-rich glucose from blood and convert it into a form that neurons can absorb. Neurons use this energy to produce neurotransmitters and eventually form ideas. The more the brain thinks, the more glucose its neurons need.

When people need to perform a mental task, the brain will burn more glucose, which will not only reduce the glucose content in the blood, but also reduce the energy source in the brain, leading to fatigue symptoms in the brain.

In addition, long-term stress and overthinking will not only damage the body's metabolism, immunity and cardiovascular system, but also lead to the decline of brain function.

Modern people are busy with many trivial things every day, which causes your brain to switch and operate constantly, so you will be easily agitated and tired. A manual worker will sleep soundly when he comes home after a hard day's work, but a mental worker will toss and turn with the pressure of the day after taking a shower. The so-called mental fatigue, nothing more.

Solution:

If you have finished the work at hand, or have a break at noon, you can take advantage of it. Closing your eyes or lying in bed for a while during this time is an effective way to fight fatigue. Some people sleep too little at night or often stay up late, and are prone to fatigue and fatigue during the day, thus reducing work efficiency. At this time, they should take a nap properly to eliminate fatigue and nourish the spirit, which will promote the health of the brain and heart.
