1, catch a cold when sleeping: Now it has entered autumn and winter, and the weather is getting colder and colder. Sleep at night, keep warm and cover with bedding. Especially older uncles and aunts, don't catch cold when sleeping at night; Young people should also pay attention to the fact that they are not moved by a little cold now, and they will come to you when they are old. Before going to bed at night, close the doors and windows and don't turn on the cold air conditioner. The bedding on the bed should be thicker, not too thin.

2, long-term no exercise: a period of no exercise, sudden running will lead to muscle soreness, which is also a very common phenomenon, I believe everyone has had such an experience, the muscles of the whole body have a feeling of soreness. High school biology class talked about this phenomenon, which is due to the anaerobic respiration of cells to produce lactic acid, which in turn causes muscle pain. If so, the pain will disappear in a few days, so you can take a rest without running in recent days and start exercising after the pain disappears.

3. Exercise is too intense: it may be a muscle strain caused by running too fast and strenuous exercise. This kind of pain is not a feeling of soreness, but a stinging pain. If it is serious, you may not be able to walk. If this is the case, I suggest you not run. Moderate exercise is good for health, but it must be moderate. Don't exercise a lot without rest, or exercise too much.

4. Other conditions: If you think that low back pain is not caused by the above three reasons, it may also be caused by disease. I suggest you go to the hospital for examination in time, and don't aggravate your illness because of your carelessness.
