Is there a scientific basis for the saying that there is a saying that idleness is idle?

Because when people are in a state of stress, adrenaline secretion will increase, and the immune system will be on alert, so that the body's immunity will be improved, which can help the body more effectively resist the invasion of germs. Once you are idle and the tension is gone, the adrenaline secretion will be reduced, the immune system will be relaxed, and the body's immunity will be reduced, but it will be more likely to be invaded by germs, and it will naturally be easier to get sick.

This sentence really makes sense, as the saying goes, life lies in sports, and all kinds of sports (such as work, exercise, travel) can strengthen the body's metabolism and exercise physical and/or mental power. You can also expand your horizons and make friends. If you are idle, your mind will gradually become dull, your physical strength will decline due to the lack of corresponding exercise, and all kinds of problems will come to your body after a long time.

Therefore, for the sake of your own body, you should also move appropriately and do what you can do.

It's true, if you are idle, you will be lazy, because if you are too idle, you will naturally be cranky. Busy people are sometimes tired, but they are fulfilling. Too idle, too long, and empty.

We can guess that when a person has a fulfilling task to complete every day, there is a certain tension in the cells of his whole body, because they need to move bricks and struggle, so they must be cheered up.

However, if one day, this person suddenly idleness and lives a life without any tasks, no pressure, and no meaning, then the cells in his body will also fall into laziness, and the immune system will also become lazy, and he will not be able to react for a while when encountering various bacteria and viruses in nature, and then he will get sick.

Of course, if a person does not belong to the kind of brick movers who are busy like dogs, and the time is particularly free, but he has his own hobbies and interests, planting flowers, reading, baking, making wine, and doing all kinds of calligraphy, painting, piano, chess, wine, poetry and flowers every day, he will not get sick.

Whether you will be idle enough to get sick does not depend on whether time is free, but on whether life is meaningful. In 2013, the Proceedings of the National Academy of Sciences (PNAS) published a study based on genetic testing that showed that pure pleasure without the pursuit of meaning in life may have little or even the opposite effect on health.

Studies have shown that people who have been in adversity, loneliness and grief for a long time are more likely to suffer from inflammation and viral infections than the general population because their pro-inflammatory genes become active and antiviral gene activity decreases.

And people who have been living without pursuit and pressure for a long time, and who are in "empty happiness", have a very similar gene expression pattern to the former. Their immune system is prone to active inflammation, which makes them more susceptible to illness.

Therefore, not pursuing life and not working hard is actually a thing that harms life and health. Many people may have had the "sweet dream" of not having to do anything and becoming a waste, but this is not necessarily a good thing. To make another conjecture, maybe it's because the world doesn't need waste, no matter how rich you are, when you don't influence the world, when you don't pursue meaning, what use does the world keep you?

No, I'm idle, I rarely get sick, and I haven't been hospitalized yet.
