The importance of good sitting posture is very common for modern people to sit still every day, especially students and office workers. Long-term study and work need to be done at the desk. If you sit for too long, your body will feel uncomfortable. At least sit in the right posture. Let's take a concrete look at the importance of a good sitting posture.
The importance of a good sitting posture 1 The wrong sitting posture is a health killer, with little visual loss and big body deformity.
At the beginning of primary school, teachers often remind students to keep correct reading and writing posture, and students will consciously or remind each other to keep sitting posture because of the novelty of just going to school. With the growth of age and grade, teachers seldom remind students, and only when they need to remind students to concentrate, will they emphasize the posture problems when listening to lectures, doing homework and reading books;
With the growth of students' age, they also have self-awareness and rebellious heart. The more teachers and parents demand, the stronger students' rebellious mentality will be, and bad habits will be formed over time.
Many students hold their chins in class and even sleep on their desks. What's more, they lean back in the chair, just like lying in bed. Some students also want to plunge into their exercise books when writing. The hand holding the pen is close to the tip of the pen and often rubs the exercise book. Some students like to read books and watch mobile phones while lying down. Although there should be many times when a book or mobile phone hits the face, it will be the same next time.
With the popularity of computers and the Internet, more and more students like surfing the Internet. Some people are addicted to online games, but they often sit hunched in front of computers or lie prone on laptops ... These phenomena exist in most students and cannot explain why more and more students wear glasses.
Students' body and eyesight are still in the development stage. If they read, write, watch mobile phones and use computers in the wrong posture for a long time, they will not only reduce their eyesight, but also have a bad influence on the development of their body shape, and even cause different degrees of damage to their cervical vertebrae and limbs, thus causing diseases. Therefore, please be sure to lead an honest and clean life and always pay attention to your learning attitude.
Keep a correct posture, don't add "windows" to your eyes, and be a tall and straight "poplar"
Correct sitting posture can not only protect students' eyesight from injury, but also help to develop a good shape of body shape. Students who don't want their watery eyes to be covered by glasses, and students who want to stand up straight, must pay attention to maintaining the correct posture of reading, writing, watching mobile phones and using computers.
1. Correct reading and writing posture
Correct sitting posture: put your back and hips flat on the back of the chair, put your feet flat on the ground, keep your knees at about 90 degrees, and put your hands on your knees.
The correct sitting posture when writing: the hips are sitting in one third of the chair, the feet are flat on the ground, and the knees are at an angle of about 90 degrees; Put your arms flat on the table, punch your chest away from the table, keep your eyes one foot away from the book, and hold the pen one inch away from the nib.
Correct posture when reading: when reading, you should first maintain a correct sitting posture, then hold the book with both hands, the upper end of the book is slightly raised, making a 45-degree angle with the desktop, and the head leans forward slightly, so that it is easy to see the font clearly and avoid neck muscle tension and fatigue. It is not correct to put the book vertically or horizontally on the table.
2. Look at the correct posture of the mobile phone and computer.
It is very common for students to use mobile phones and computers, so it is necessary to remind students to keep correct posture.
Pay attention to when using mobile phones:
(1) Don't watch your mobile phone in class, it's easy to get distracted.
⑵ Don't watch your mobile phone while walking, which is prone to accidents and traffic accidents.
⑶ Don't watch your mobile phone in the car, it's easy to get carsick.
(4) Don't watch your mobile phone in the dark. This is the most eye-damaging behavior, which can easily lead to blindness.
5] Don't look at your mobile phone while lying down, it will damage your eyesight and make you face easily.
[6] Don't look down at the mobile phone for a long time, which is easy to cause cervical spondylosis.
Fighting posture when using a computer:
(1) The upper body should keep the neck upright, so that the head is supported, the shoulders naturally droop, the upper arm is close to the body, and the elbow is bent at 90 degrees. Operate the keyboard or mouse to keep the wrist as horizontal as possible. The center line of the palm and the center line of the forearm should be kept in a straight line. The waist of the lower body is straight, the knees naturally bend 90 degrees, and the sitting posture with both feet on the ground is maintained.
⑵ Be sure to choose a desk and chair with ergonomic design and use a special computer chair. Sitting on it should follow the "three right angles": the first right angle is formed at the knee under the computer desk, the second right angle is formed at the thigh and back, and the third right angle is formed at the elbow joint of the arm. Lean your shoulder blades against the back of the chair, put your shoulders down and keep your chin away from your neck. Look straight at the center of the computer screen, preferably with a supported chair back and armrest, and the height can be adjusted.
⑶ Keep an appropriate distance between your eyes and the monitor. The eyes and computer monitor form a slightly downward gaze angle on the screen, which can relax the neck muscles.
(4) When using the computer, you should rest for 5 ~ 10 minutes every hour, do soft exercise or local massage, and at the same time develop regular exercise habits, and train your shoulders, neck and upper limbs for stretching and muscle strength to increase softness and muscle strength.
5] The height of the computer should be appropriate. Install the center of the computer screen at the same height as the operator's chest, and it is best to use a chair with adjustable height. There should be enough space to stretch your feet, your knees naturally bend 90 degrees, and your feet will not leave the ground. Don't cross your feet.
A good study habit should include a correct study attitude. A correct study attitude of students not only helps to concentrate in the study process, but also protects the healthy development of eyes and all parts of the body. Moreover, when you have a correct learning attitude, your learning confidence will be stronger.
If you have developed a bad learning posture, you should correct it in time when you find that the posture is incorrect and maintain a correct sitting posture. As long as you can persist for a period of time, you will certainly find the correct learning posture.
The importance of good sitting posture 2 1. Sitting up straight can strengthen your bones.
Good posture helps to relieve the pressure on the spine, help the bones to play their proper functions, and make the bones stronger and healthier.
2. Raise your mood.
Through many experiments, Dr. Eric Pepa of San Francisco State University found that participants who walked through the hall with their arms held high felt more energetic, happier and more active. Participants who walked listlessly through the hall felt more sad, lonely, isolated and sleepy, just like zombies.
3. Improve memory.
Another experiment by Dr. Pepa found that it was easy to arouse participants' negative memories when they were sitting lazily and looking down. However, when sitting up straight and looking forward, many participants said that they rarely had negative memories and recalled positive things more easily. One theory is that sitting up straight can increase cerebral blood flow and oxygen supply. ...
4. Enhance self-confidence.
Ohio State University conducted a study on the correlation between sitting posture and self-confidence among 765,438+0 students. The results show that students with correct posture are more confident in answering the questionnaire, and good posture enhances their confidence.
The importance of good sitting posture. Improper sitting posture is harmful.
The so-called correct sitting posture means that the spine keeps a natural curve when sitting, but it is the same as lying and standing. This is an important measure to relieve back and neck pain.
Sammy Margo, a spokesman for the Royal Physiotherapy Association, said: "Sitting hunched will oppress the abdomen and reduce the oxygen and nutrition supply here, so the digestive system will be affected, making people feel sleepy and dull."
You know, if you sit incorrectly, you will also have shortness of breath. Sammy said: "In this case, the body will be attacked by default, which will increase the pressure, thus affecting the quality of sleep and energy level." Therefore, after a day's work, you have no remaining strength to live as a husband and wife when you come home, and some people have no desire at all.
The above-mentioned "new study" conducted an experiment on 74 subjects from New Zealand to observe the difference between sitting up straight and hunching over. Subjects were randomly divided into sitting posture group and hunchback group, both of whom wore back posture correction belts to ensure posture. These subjects do not understand the purpose of the study, so there will be no psychological factors affecting the experimental results.
After putting on the corrective belt, I began to read books, and my heart rate and blood pressure were monitored. There is also a special stress speech test to create a stressful environment, and then evaluate people's ability to withstand pressure, changes in mood and changes in confidence.
The experimental results show that people who sit correctly have stronger self-confidence, higher frequency of sexual desire, more favorable emotions and less fear of stress. When taking part in the speech test, the person who sits correctly also said more than the other group. The other group uses more negative words and uses singular first person frequently, which shows that they are caught in a self-centered dilemma. They talk more about sad things and seldom describe positive emotions.
The researcher who conducted the experiment said, "Maybe just by sitting up straight, we can help people improve their ability to cope with stress." This report has been published in the journal Health Psychology.
There have been similar research results before. A study by York University in Canada found that 92% of respondents believe that sitting up straight is easy to produce more positive thoughts. There are also some studies that posture will affect personal performance, and students with correct posture generally get better grades than those with incorrect posture.
Sammy thinks this conclusion is the same as the theory that a smile can make you happy. "The correct posture makes people's psychology correct; Bad posture will lead to bad emotions, and bad emotions will further encourage people to pose bad postures, which means a vicious circle. "
