Questions about health

Everyone is eager to have a healthy body. In our daily life, there is a lot of common sense closely related to health. I don't know if you have noticed. 1. The computer emits the highest radiation value during startup. Please press the startup button and stand up and walk away to avoid radiation. When using a computer, if you can keep the distance from the screen above 40 cm, the radiation of the computer to the human body will be much reduced. 2, going to the toilet is very convenient, I don't know how much more comfortable than squatting. But in fact, squatting in the pit is most conducive to the operation of the gastrointestinal tract. Moreover, because the toilet directly contacts the skin, many people use it, which is easy to cause the spread of some diseases. 3. Some people love cleanliness and take a bath every day. The water temperature is very high and they feel very sanitary and comfortable. As everyone knows, this practice is equivalent to destroying the stratum corneum on the surface of the skin, and the function of stratum corneum is to protect the skin and make it difficult to lose water. Therefore, most people who take a hot bath every day feel that their skin is dry and itchy, while those who take a special bath are more likely to itch. Therefore, if you often sweat in summer, you can take a bath every day. It is enough to wash twice a week after the weather turns cold, and the water temperature should be controlled as long as the skin does not feel cold. 4. Pay attention to children's shoes that like to dye their hair. If you plan to dye lighter colors, such as silvery white and light yellow, then you will be hurt more by chemicals than by dyeing dark colors such as red and purple. Because if you want to turn the original black into a light color, you must first dilute the primary color before you can color it. Moreover, this decoloring agent is very harmful to human health, which is much greater than coloring agent. 5. Using boiling water when cooking can not only shorten the cooking time, but also protect the nutrients in the rice to the maximum extent.
