7 Reasons You’re Dealing With Seriously Low Energy And Brain Fatigue

Bad lifestyle habits are also a major cause of brain fatigue. Therefore, it is more important than anything else to develop habits that do not allow fatigue to build up. In this section, let's look at some of the wrong habits that can increase brain fatigue.

1. Strenuous Exercise Suddenly May Cause Brain Fatigue

As the centenarian age approaches, people are becoming more concerned about their health than ever before. Probably because of this, more people are starting to exercise, but we often see people losing their health because they suddenly start exercising. Some people who don't exercise at all suddenly jog for too long one day and get plantar fasciitis and can't walk properly. There are also many people who break their muscles and injure their bones when they overdo the kettlebell push-ups at the gym. Some people have even lost their lives after their hearts stopped beating when they participated in a marathon.

If you suddenly go into a sport that you have not trained for, you will have problems with your body. From a brain science point of view, this is because the autonomic nerves are not properly regulated. When the sympathetic nerves are overworked, the brain requires a lot of energy, which increases the amount of oxygen consumed. With the rapid increase in reactive oxygen species, cellular oxidation becomes more severe. As a result, the granulosa and microvasculature of the cells are damaged, which in turn has a serious impact on health.

2. Long working Time May Cause Brain Fatigue

Even simple tasks, if done repeatedly over a long period of time, can cause fatigue to build up. The more fatigue is accumulated, the more energy is used up and the demand for oxygen and reactive oxygen species increases.

When we need to take a moderate break like this, our body automatically sends out signals and we must heed and obey them. Unfortunately, it is not easy for us to recognize the fatigue signals sent by our brains. Therefore, it is important to take regular breaks when working long hours. Resting before you feel tired is the most efficient way to rest.

3. Duplicate Working May Cause Brain Fatigue

There is a rule called the Law of Diminishing Marginal Effectiveness. It means that no matter how interesting something is, if you do it over and over again, the fun will be halved and you will get bored. If the same circuit is used all the time, the threshold for information transmission (the minimum amount of stimulation required to generate excitement) rises. In other words, the neurological capacity of the brain decreases and it can no longer transmit information at the same level of stimulation. This is the first sign of brain fatigue.

At this point, it is more productive to do other things. If you feel bored after an hour of maths, it may be more appropriate to read English instead. This will help to reduce fatigue by using other circuits of the brain.

4. Maintaining the same posture May Cause Brain Fatigue

The longer you stay in the same position, the more likely your body is to build up fatigue.

If you sit in a narrow, uncomfortable chair for long periods of time, your legs will become swollen and numb, and in severe cases, your blood will clot. 

Therefore, if you feel bored and tired, you should change your posture and stretch your body. When the body curls up, the lungs close up, leading to a lack of oxygen and a tendency to secrete aggressive noradrenaline. In contrast, if we relax or take a gentle walk, the lungs open up completely and produce serotonin, allowing us to rest.

This light stretching and exercise is also an important part of the autonomic nervous system. Look at a boxer. During a fight, a boxer will pull his body up to avoid being hit by his opponent's fist. But if the round is over, the fighter will straighten up and relax as much as possible. They are instinctively taking a resting position. At this point, the lungs open and the brain produces serotonin, thus reducing fatigue.

5. Focus on one thing too long may cause brain fatigue

The common denominator of people who excel in all areas of life is that they have a higher level of concentration than the average person. Concentration maximizes the capacity of the brain and increases productivity significantly.

But this concentration activates the sympathetic nerves and consumes a lot of energy. In particular, focusing on one thing, like anaerobic exercise, is an activity of the glycolytic system, which in turn increases fatigue.

The more you concentrate, the more often you need to give your brain a rest. A high level of concentration, like a fire that can ignite a piece of paper, is not sustainable. 

6. Force yourself to do something you don't feel like doing

When working, the sympathetic nerves are dominant and the brain secretes pro-adrenaline. When you are forced to do something you hate, you produce more positive adrenaline. The autonomic nerves are then out of balance, and in order to restore balance (to maintain internal homeostasis), more energy is required and brain fatigue increases.

The problem is that we have to do things even if they are annoying, and this is the reality we live in.

It is time to think differently about why we do what we do and find the value of that thing. No matter how insignificant it is, it can be helpful and have a value that we don't know about. Even if you are doing the same thing, just thinking about it differently and convincing yourself can reduce your brain fatigue.

7. Habit of working late May Cause Brain Fatigue

Since primitive times, people have been working when the sun rises and resting when the sun sets. In fact, our parasympathetic nerves take over at night and the body produces less of all the active hormones. In other words, the body's functions become slower. If we do things at this time when the sympathetic nerves are dominant, we will be less productive and our brain fatigue will be worse.

Therefore, try to go to bed between 11pm and 2am. The first 90 minutes after falling asleep during this time is also known as 'obligatory sleep', as this is when we get the deepest sleep. It also has the best effect on fatigue.
