Young white-collar women are prone to constipation.
In addition to the symptoms similar to a cold, most women feel that "swallowing" is not enjoyable. Because they sit in the office for a long time, their intestinal peristalsis becomes worse, and it is difficult to promote defecation. Especially people with habitual constipation.
For these people, this season is not only dry stool, but also slow defecation every time they go to the toilet, or the cycle is longer than usual, exceeding the usual habit of 1 day, or even not defecating for three consecutive days, which is typical autumn dryness constipation.
In this case, everyone's first task is to solve the problem. Eat more fruits, do more exercise and take some Chinese medicine to help defecate. For example, it can be a good solution to insist on exercising before going to bed every day.
Take a walk, for example, or massage your stomach clockwise around your navel every night before going to bed 100 times. In this way, you can basically defecate smoothly the next day. Young people can also do sit-ups before going to bed to strengthen abdominal muscles.
Second, it is not advisable to do sit-ups when getting up.
Many athletes use sit-ups as a form of exercise, but they may bring unexpected consequences, such as back pain. Stuart, a professor of spinal biomechanics at the University of Waterloo in Canada? McGill has been studying sit-ups for many years, convinced that the traditional belly roll will be harmful to health.
In the Biomechanics Laboratory of Spine, he conducted dozens of studies on pigs. By imitating people's sit-ups, he kept bending the pig's spine for hours at a time.
Later, he examined the spinal disc of the pig and found that the convex part had been squeezed into a sharp shape when bending. If the same thing happens to people, it will compress nerves, cause back pain and even disc herniation.
The reason why pigs are chosen as experimental objects is that compared with other animals, the pig's spine is more similar to that of humans. Of course, some opponents pointed out that there are still many differences between people and pigs. In addition, it takes too long to bend the pig's spine during the study. For people, no matter how hard they train, there will be a rest in the middle.
Perhaps these research results only illustrate the consequences in extreme cases, even so, injuries may still occur. In 2005, a study of soldiers stationed in fort bragg showed that 56% of soldiers were injured by sit-ups in the military physical fitness test every two years.
For some people, sit-ups seem to be more prone to low back pain. On the contrary, some people do 30 sit-ups every day for decades, but there is nothing unusual.
A report shows that most problems are not caused by constant friction, but by genetic factors. 75% people have or do not have back problems because of heredity.
So sit-ups may cause back pain, which only applies to some people. Professor Stuart McGill suggested sliding his hands to his lower back to avoid direct contact with the floor.
This will minimize back pressure. Bend one knee and keep the other knee straight. Then lift your head and shoulders slightly off the ground. He said, imagine your head resting on the bathroom scale. All you have to do is raise your head and let the scale show 0.
Brett contreras of Auckland University of Technology in New Zealand has studied sit-ups, and the results show that each group of spine exercises should not exceed 60 times, starting with 15 times, and then gradually increasing.
In addition, after sitting at the desk for a long time, please don't get up immediately and start sit-ups on the floor; The first thing in the morning is to avoid this sport.
