In recent years, the incidence of cancer has been increasing. The latest cancer report "China Cancer Morbidity and Mortality in 2016" released by the National Cancer Center of China (cancer data statistics are usually delayed by 2-5 years) shows that in 2016, there were about 4.064 million new cancer cases in China and about 2.4135 million cancer deaths. is equivalent to 464 new cancers and 276 deaths from cancer every hour.
And rumors about cancer in life are also happening one after another. For example, some people say, "When you sleep at night, there will be radiation on the head of the bed, which will cause cancer." Is this true?
In fact, there are two types of radiation -
◎Ionization radiation: can destroy human tissues or DNA, causing cell mutations, damage or death. X-rays and CT are all ionizing radiation (but the radiation of X-rays and CT are not large, so don’t worry if you do it once occasionally);
◎Non-ionizing radiation: converts energy into temperature to increase, achieves the effect of heating, and its impact on human health is basically negligible. The most common ones are mobile phones and computers.
is visible. When you go to bed at night, put your phone at the head of the bed. The radiation generated by is almost non-cancer . However, when the phone is on, it will constantly send high-frequency electromagnetic waves . will affect the sleep quality to a certain extent , so it is still recommended not to place the phone at the head of the bed, it can be slightly farther away.
