This is because labor can stimulate the growth of cerebral capillaries and promote blood circulation, thus increasing the blood flow of the brain and increasing the oxygen supply.
If there is insufficient oxygen supply to the brain, it is easy to feel dizzy and unable to concentrate. Through labor, the oxygen supply to the brain increases, which naturally makes people energetic, focused and improves the efficiency of work and study.
Delivery can also stimulate the brain to secrete dopamine.
As we all know, dopamine is a neurotransmitter secreted by the brain, which can make people feel happy and reduce troubles. Smoking and drinking can stimulate the secretion of dopamine and make people feel happy, which is one of the reasons why smoking and drinking can be addictive.
In contrast, this way of producing dopamine through labor is much healthier.
The Nutrition Society of China suggests that healthy adults should achieve the activity equivalent to 6000 steps a day and 40000 steps a week.
20 18 September, WHO reported that 0/4% adults in China/KLOC-0 did not get enough exercise.
From the data point of view, it's not bad, but WHO specifically pointed out that this is because there are many elderly people in China who like to dance square dance, which boosted the data. If we only look at the middle-aged people in China, the proportion of insufficient exercise is higher.
In fact, this is also conceivable. Now, many white-collar workers are busy with their work. Even if it doesn't reach the level of "996", overtime is a common occurrence. They don't go to the canteen to eat, often order takeout, and have no time to exercise.
Even if there is a chance to have a holiday, it is still a state of "old vines, air-conditioned wifi watermelons, Ge You sofas with the same style, and I will lie down when the sun goes down", which leads to long-term lack of activities.
In fact, this problem is easy to solve. If you really don't have the time and energy to go to the gym, you might as well quit take-out first, don't need hourly workers, be diligent and do housework yourself.
Take sweeping the floor, mopping the floor and vacuuming. Every 8 minutes can be equivalent to 1000 steps of activity.
Similarly, the folding stack is converted into 1000 steps every 20 minutes.
Cooking or clearing the table is equivalent to walking every 13 minutes 1000 steps.
Washing dishes or ironing clothes is equivalent to walking every 15 minutes 1000 steps.
In other words, completing the housework that must be done every day is basically enough for the necessary activities of one day.
