If the sofa and air conditioner are not used properly, what harm will they bring to the body?

If the sofa is too soft, the support of the center of gravity of the human body will be unstable, and people will move their bodies intentionally or unintentionally to seek new balance and stability of the body, so sitting on a soft sofa for a long time will make people feel back pain, tiredness and fatigue. At the same time, sitting on a soft sofa makes it difficult to maintain the normal physiological curvature of the spine, which will make the back muscles tense and induce or aggravate low back pain for a long time.

There are too many air conditioners, too low temperature will catch a cold, and it is easy to catch a cold due to the temperature difference when you often go in and out of the air-conditioned room. If you don't clean it for too long, you can easily get sick due to bacteria, air conditioning disease, etc.
