Why do you get tired after working for a long time?

I am studying medicine, and the main energy for the brain is sugar, so mental exercise will accelerate the energy and increase blood circulation, so it will naturally increase oxygen consumption. And after a long period of mental activity, people will feel very hungry, dizzy, and sometimes feel poor breathing. Brain exercise consumes a lot of energy, so you should replenish sugar in time, eat some sugary foods when you are tired, breathe fresh air in front of the window, replenish oxygen, and your symptoms will be relieved.

Many factors can contribute to feeling tired while sitting at work. Here are the causes that can affect physical and mental fatigue:

1.Lack of physical activity: Sitting and working all day limits the range of physical motion, which is not conducive to blood circulation and can easily lead to muscle fatigue and stiffness. Prolonged static posture may also increase the risk of back and neck pain.

2.Eye strain: Prolonged staring at a computer screen can easily lead to eye strain, dryness, and nervousness, and you may suffer from eye fatigue syndrome.

3.Mental stress: Sitting at work for long periods of time may require constant concentration and repetitive tasks. These factors can increase the burden on the brain, leading to mental health problems such as depressed mood, fatigue and insomnia.

4.Malnutrition: Sitting in the office for long periods of time can make it easy to neglect eating habits. Too much or too little food, or an uneven diet, can lead to physical fatigue and lack of energy.

In summary, sitting for long periods of time at work can trigger physical and mental fatigue, and the lack of adequate physical activity can increase the risk of physical discomfort. To alleviate this fatigue, you can rest as much as possible and do some light exercise, while also focusing on adequate diet and good sleep quality.

In modern society, more and more people need to sit for long periods of time at work. This sedentary way of working often leads to physical discomfort and increased fatigue. Let's explain why sitting for long periods of time can be tiring, both physically and mentally.

1.Physical causes.

Sitting for a long time can lead to a passive state in which the muscles are not fully mobilized, which affects blood circulation and metabolism. This makes it easy for metabolites to accumulate in the body, causing a burden on the body and causing fatigue. In addition, sitting for too long can also increase the pressure on the lumbar spine, damage the intervertebral discs, and cause problems such as back pain.

When the body is in a state of discomfort, it is natural to feel tired.

2.Psychological causes.

Sitting for a long time will not only have a negative impact on the body, but also on the psyche. In a closed office space, with a lack of sunlight and air, people tend to feel depressed and dull. At the same time, a large number of work tasks and a monotonous office environment can easily make people feel anxious and stressed, which can increase fatigue.

In addition, sitting for long periods of time can also make people lose motivation and enthusiasm, reduce work efficiency and productivity, and negatively impact individuals and teams.

In order to reduce fatigue at work, we can take the following measures:

1.Appropriate physical activity: Stand up and move at work, or do some simple stretching exercises, which can promote blood circulation and muscle activation, and relieve physical discomfort.

2.Adjust the office environment: Adding some greenery, increasing air humidity, and maintaining good ventilation in the office can improve the indoor environment and relieve the feeling of depression.

3.Arrange work tasks reasonably: Set reasonable work plans and goals, assign tasks appropriately, and avoid overwork and anxiety. At the same time, you can try to adjust your mentality, maintain a happy mood, and increase the fun of work.

4.Use office furniture: Choose ergonomic office chairs, mice, keyboards, etc., to reduce fatigue on your body.

In conclusion, sitting for long periods of time at work can be tiring, but there are a few things we can do to ease the discomfort. By adjusting the working environment, arranging tasks reasonably, exercising the body, etc., it can help us better cope with the problem of sedentary at work.

To get straight to the point, everyone feels very tired when they sit for a day of work, because the state of sitting without using their brains and hands not only keeps the muscles loaded, but also puts the body and the functions of the trembling brain in a state of high tension. Specifically, the stress that the workplace may bring to us is the following: unnatural body posture, lack of exercise, high psychological load, and so on.

Unnatural body posture.

For white-collar workers, sitting in the office has become a daily routine. Sitting for long periods of time can not only cause back pain, but also neck, shoulder, and wrist pain. Once you are sedentary, the following problems arise.

The first is cervical spondylosis. Working in front of the computer for a long time, many people will have the habit of looking at the screen. Looking down at the screen for a long time, the pressure on the cervical spine will increase, and if you are sleepy for a long time, you are prone to cervical spondylosis.

This is followed by lumbar spondylosis. The lumbar spine is subjected to greater gravity, while in a sedentary state, the support of the spine is weaker, and the pressure on the lumbar spine increases. Therefore, it is easy to lead to diseases such as lower back muscle soreness, lumbar disc herniation, and bone hyperplasia.

Again, muscle fatigue and bone fatigue. If you sit for a long time, your body posture is monotonous, and your body's range of motion is also limited, and if you don't exercise for a long time, you are prone to muscle fatigue and bone fatigue.

Lack of exercise. Sitting on a seat for a day to work can be said to be the most harmful to our Jianwang Zheng Liankang. Although a person's activity level is low, the impact on the organism is very large.

As a result of sitting in a seat, the body's energy metabolism slows down, and it is so easy to lead to lifestyle diseases such as obesity, high blood pressure, cardiovascular disease, etc. in the long term. Long-term lack of exercise can also lead to muscle atrophy. Muscles are not only used for physical exercise, but also perform important functions for the body to burn calories and control blood sugar, and if the muscles are atrophied, it may lead to a decrease in the body's function in the long run.

Psychological load is high.

In the office, whether it's work pressure or relationships between colleagues, it can be psychologically taxing. When you are in this state for a long time, your brain will feel tired and will no longer be able to concentrate on your tasks or thoughts. Moreover, working day after day is also easy to bring people negative emotions such as boredom and depression.

In general, everyone will feel very tired after sitting for a day of work, mainly because of the long fixed posture, lack of exercise and high psychological pressure, which will put the body and brain in a state of high tension, resulting in physical and brain fatigue. Therefore, if you want to improve work efficiency and reduce physical fatigue, you should take timely rest, do some sports, eliminate negative emotions, adjust posture, etc.

When working, a lot of physical and mental power is consumed, so after a long time, the physical and mental consumption is too large, and the human body will appear to be fatigued.
