When you hear the radiation! Are you afraid? Leukemia, brain cancer, alopecia, infertility, abortion. With people's attention to medicine, the harm that radiation can bring is well known to us, which causes many netizens to come up with various anti radiation measures. "Radiation protection is right, but the premise is to understand that you want to protect against ionizing radiation." According to experts, ionizing radiation refers to a kind of high-energy radiation, which will damage physiological tissues and cause harm to human body. This kind of damage generally has cumulative effect. Nuclear radiation and radiotherapy are typical ionizing radiation.
For example, the heating and heating of household appliances, such as microwave and electric heater, are accompanied by infrared radiation every day. The radio waves emitted by communication base stations also belong to non ionizing radiation electromagnetic waves. It only produces a thermal effect and will not cause harm to human body.
What's more, there is no evidence that almost all of the current popular radiation protection products, including radiation protection plants and radiation protective clothing, can protect against radiation, and there is no evidence that they are beneficial to health. "Ten thousand steps back, even if computer radiation is harmful, all radiation in nature is in a straight line, or reflected and then straight-line transmission. No plant can make the radiation turn and gather. It is impossible for us to face the cactus directly to the computer screen. Therefore, the significance of cactus radiation protection cannot be discussed." Experts said.
It's better to put a bottle of water than a cactus beside the computer
In fact, sitting next to the computer should really worry about not electromagnetic radiation, but "sedentary" itself.
According to experts, many studies have shown that sedentary is related to many health problems and diseases, such as obesity, hyperlipidemia, hemorrhoids, bone and joint diseases; there have been studies on pulmonary embolism caused by sitting for a long time, with sudden death in severe cases; even studies have suggested that sedentary people have an increased risk of cancer. Moreover, it seems that the physical damage caused by sedentary can not be eliminated by exercise. In other words, after work fitness activities can not offset the impact of sedentary work. For sedentary people, reducing sitting time is more beneficial than regular exercise.
It is necessary to promote the importance of drinking water if it is unavoidable to be sedentary because of work and environment. In fact, whether sedentary or not, individuals should keep enough water every day. But drinking water is especially important for sedentary people.
The human body is losing water almost every moment. Every time a carbon dioxide molecule is exhaled, a water molecule will be discharged at the same time. Although the water exhaled each time is very small, it is breathing all the time. Therefore, the amount of water lost through the respiratory tract every day is considerable. At the same time, the internal metabolism of human body also needs water, and the waste produced by metabolism must be discharged in the form of urine. These quota drainage is not reduced because of the lack of drinking water. If the quota is reduced, the accumulation of metabolic waste will affect the internal environment of the body, and the mental and physical activity capacity will be reduced. When the human body feels the lack of water in the body, it will try to reduce the blood supply of some organs. Because the lower limbs are farthest away from the heart and are in the lowest position, they are also affected most. The combined effect of reduced blood flow and sedentary, lower extremity blood stasis is slow, it is very easy to form deep venous thrombosis. If the thrombus falls off and flows into the pulmonary artery through the right atrium and right ventricle, it can lead to a fatal pulmonary embolism. According to media reports, some teenagers who died of sudden death online all night long died of acute pulmonary embolism.
Experts advocate that we should take a glass of water in front of you before you start to use the computer for a long time. We should drink regularly during work and games. After drinking a cup, remember to fill it up.
One of the benefits of this is to keep the body hydrated enough to reduce the risk of dehydration, including pulmonary embolism; the other is that regular drinking water can produce regular urination, which makes us have to stand up and move.
