Brief:
There is one kind of gadget that is now becoming more and more popular in American schools - fidget spinners. This is a toy that is placed in the hand to play, as long as the hand pinches the spindle and gently pushes it can rotate at high speed and continue to rotate, which can be used to relieve the pressure between them, once the hand can not stop at all. Fearing that students would be distracted in class, many schools banned the toy.
One gadget is now becoming increasingly popular in American schools – Fidget Spinners. This is a toy that is placed in the hand to play, as long as the hand pinches the spindle and gently pushes it can rotate at high speed and continue to rotate, which can be used to relieve the pressure between them, once the hand can not stop at all. This gadget is becoming more and more popular in schools. Fearing that students would be distracted in class, many schools banned the toy.
This little toy called Fidget Spinners can satisfy your little habit of moving.
But it's not just children who like to move around and be idle. Look at your colleagues around you, and you may see someone shaking their legs, someone spinning a pen, someone chewing something in their mouth, someone biting their lower lip, or someone putting a beard. These all seem like completely subconscious movements that everyone does every day.
Why are some people more active than others?
But why are we always moving? Why are some people more active than others? And if this "hyperactivity" can help us get rid of stress, does it mean that we should all do it? These questions are actually difficult to answer because there is no qualitative understanding of the causes of this "hyperactivity" phenomenon. However, we have found some interesting theories that may explain this phenomenon.
Regulates attention
Cognitive theory research shows that "hyperactivity" is closely related to our attention level. In other words, "hyperactivity" is a self-regulating mechanism that can help us increase or decrease our attention level according to the needs of the human body - calm or active.
People who are constantly "moving around" are more likely to lose their minds. At work, if we lose our mind, we become "hyperactive." If you lose your mind, your work performance will decline. Similarly, your job performance deteriorates when you're "moving around" – hyperactivity has been shown to affect memory and comprehension.
This suggests that "hyperactivity" can be a challenge to concentration. But it can also be the method of [concentration]. "Hyperactivity" can provide physiological stimulation to improve our concentration and energy, so that we can better focus on the work at hand.
▲ Many girls like to play with their hair every day.
There is an experiment that supports this theory. In one set of tests, a group of testers were allowed to scribble while listening to a phone conversation, and in the end, this group of testers remembered more phone details than those who were not allowed to doodle. We also know that children with ADHD do better on some cognitive tests when they allow their bodies to move around (however we did not see similar effects in children without ADHD).
Weight management
However, biological science presents us with a different picture. The following example suggests that "hyperactivity" may be a physiological response that helps us subconsciously maintain our weight.
An article published in the journal Science in 2000 laid down this theory. In the experiment, the researchers selected a group of healthy, non-obese volunteers who fed each person 8,1000 more calories per day than the normal diet for <> weeks. Volunteers combat this extra heat by "hyperactivity," changing standing and sitting positions, and tensing their muscles from time to time. However, the weight that each volunteer ended up gaining was very different. However, this is very related to the degree of "hyperactivity" - the more people move, the less weight they gain.
Research and studies:
But how can such small actions such as shaking legs, turning pens, and pulling beards make such a big difference? Studies have shown that doing "small movements" while sitting or standing can increase calorie expenditure by 29% and 38%, respectively (compared to lying still). Correspondingly, "hyperactivity" can help you burn 100-800 calories per day.
WHO estimates:
The World Health Organization (WHO) estimates that we only need to eat 100-200 more calories per day than we should absorb, and we will continue to gain weight, so through "hyperactivity", we can effectively offset these excess calories. So, "hyperactivity" is like an alarm device in the body. In a 12-year experiment, researchers followed 12000, women and found that among those who sat for long periods of time each day, the higher the degree of "hyperactivity," the lower the mortality rate.
Unfortunately, you can't learn how to be "hyperactive" because it seems to be innate. There are even some genetic causes in it – studies have shown that similar "hyperactivity" occurs between family members and twins.
Decompression?
The final explanation for "hyperactivity" is that this behavior is a coping mechanism in the face of stress. These theories of hyperactivity often focus on patterns of behavior for "personal contact"—such as pulling hair, scratching skin, etc. Then, it's unclear whether these behaviors represent a particular class of "hyperactive" behaviors.
▲Many people love to gnaw their nails when they are stressed.
In one study, scientists increased stress on test takers by arranging some male test takers to do math problems in front of strangers. They found that those who became more anxious in the test had more small movements when doing math problems. However, those who subconsciously plucked their hair during the test reported relatively low levels of anxiety, meaning that "small movements" helped reduce stress. However, small movements and anxiety levels were not directly linked. Interestingly, this effect was only seen in male testers.
