Cactus protects against radiation, true or false
Myth: Computer workers usually have a pot of cactus on their desks to protect against radiation. Most people believe that cactus has a strong resistance to ultraviolet rays in the sun and must have the function of absorbing radiation.
Truth: Cacti like sunshine and live in arid environments for a long time. In order to prevent excessive transpiration, large areas of the leaves have evolved into needle shapes. This biological property makes people mistakenly believe that it has radiation protection function. However, there are still no reports to prove the scientific validity of this statement.
Although the cactus has a strong resistance to the light radiation emitted by the sun, the radiation emitted from the computer screen is radio wave radiation that radiates in a straight line. There is an essential difference between the two. It does not necessarily mean that it can absorb ultraviolet rays. Can absorb radio wave radiation.
Although it has little effect in protecting against radiation, the cactus as a potted plant is not without its merits. It is not only a natural oxygen bar at night, but also a master at absorbing dust and can purify the environment.
Can eating less at night help you lose weight?
Myth: Losing weight is a topic that modern people never tire of talking about.

The main culprit of obesity is that the overall caloric content of the diet is too high. Whether food intake and consumption are balanced is the key to determining weight gain, loss, or maintenance.
