Mental work has the function of improving intelligence within the scope permitted by the body, so that the cells in the cerebral cortex can be active.

It is impossible for people not to use their brains. This is "I think, therefore I am".

Similarly, manual labor can make our bodies get full exercise, especially muscles and joints, promote and improve the blood circulation of the whole body, speed up metabolism, make the brain get enough nutrition and oxygen, and help to eliminate brain fatigue.

It can be said that the benefits of exercise to the body are similar to those of manual labor. Compared with the former, manual labor has the following advantages:

◆ Physical labor is mostly carried out outdoors, which belongs to aerobic exercise, but exercise and fitness are not necessarily.

Different from physical exercise, it often only exercises a certain part of the body. Doing manual labor often requires physical coordination, which can exercise the muscles and bones of the whole body. Think about hoes, which need not only the strength of hands, but also the waist and legs to help the brain and eyes accurately judge the placement and strength of hoes.

The purpose of physical labor is clear, and the brain and eyes should be involved in planning while working, so as to achieve the state of integration of body and mind, especially some physical labor, which can obviously enhance the coordination of body and mind (brain).

◆ The most important point is that physical exercise simply consumes calories and fat (Liu Tangjun's colleague Xiao Lizi whispered BB: it also consumes money for fitness cards), and manual labor can create value! When we have accomplished something and harvested the fruits of our labor, our hearts are happy and our sense of accomplishment is beyond words!

There is also a view that physical exercise is to exercise the body, while manual labor is to use the body.

There is some truth in this statement, but it refers to long-term and high-intensity physical labor, which will definitely cause harm to the body.

Pay tribute to our parents, grandparents and migrant workers.

So what we advocate is moderate, average weekly physical labor.

First of all, the frequency should not be too high, the time should not be too long, and the intensity should not exceed what the body can bear. Work and rest should be combined to avoid lumbar muscle strain.

Secondly, just like you need to warm up before exercise, don't roll up your sleeves as soon as you go on stage to do manual work (it is easy to get angry). You need to start gradually and slowly mobilize the vitality of your muscles and bones.

Thirdly, to do manual labor, we should try to avoid repeating an action for a long time, consciously achieve the goal in the process of labor, and fully relax our whole body.

Finally, don't forget to wear labor insurance products to avoid injury and sunburn.
