Not long after Aunt Liu retired, she came to her son's house to help take care of her grandson. But the grandson is still young, and he is very troublesome, so that Aunt Liu can't sleep well every night and often loses sleep.
At this time, she will swipe her mobile phone to relieve her boredom, but it often takes an hour or two to swipe.
After a period of time, Aunt Liu found that her eyes were very wrong, her vision was blurry, and she was very afraid of light, but after going to the hospital for examination, she found that the intraocular pressure in her left eye was as high as 50mmHg, and she was diagnosed with angle-closure glaucoma.
After some understanding, the doctor said that this may be related to Aunt Liu's frequent use of the light and mobile phone at night, and this disease is also very serious and requires immediate surgery.
1. How harmful is the radiation of mobile phones? Can it cause cancer?
In daily life, it is common to hear remarks about the harmful effects of mobile phone radiation. We all know that radiation is harmful, but we don't know that there are actually two types of radiation, which can be divided into ionizing radiation and non-ionizing radiation.
Ionizing radiation refers to radiation with a sufficiently high radiation energy, such as radiation produced by nuclear radiation, CT scans, etc. Long-term exposure to these radiations can easily lead to cell cancer, infertility and fetal death, and the radiation that we often call harmful to health is ionizing radiation.
Non-ionizing radiation refers to radiation with low energy and does not ionize atoms, such as microwaves, radio waves, etc. The radiation generated by the electrical appliances and mobile phones we use every day is non-ionizing radiation, and the frequency of these radiations is very low, so it does not pose an excessive risk to health, and there is no need to panic.
If mobile phone radiation is so safe, why does the International Agency for Research on Cancer classify mobile phone radiation as a Group 2b carcinogen, that is, carcinogens that can cause cancer.
In fact, this category 2b "probable carcinogen" is only a possibility, but it cannot be proven, and further research is needed, including everything, and even coffee.
The reason why mobile phones are included in the category of carcinogens is also because of a study in Sweden a long time ago. Studies have shown that people who use >mobile phones for more than 10 years for more than 10 years have a higher risk of developing a brain tumor than those who do not use mobile phones (from 0.005% to 0.016%).
However, this study is very controversial in the scientific community, because its design is not rigorous, the data source is not an objective record, but through the subjects themselves to fill out the form, few people will remember how often they used their mobile phones in the past 10 years, right?
However, the International Agency for Cancer (IARC) has included it in the category of category 2b carcinogens, based on the principle of preferring to believe that it is not credible or not.
Huang Xiang, attending physician of the Department of Neurosurgery at Huashan Hospital affiliated to Fudan University, said that the evidence of mobile phones causing cancer is relatively limited, but we still need to be vigilant about whether we are overexposed.
Just like basking in the sun, regular exposure is good for the body, but long-term overexposure can also increase the risk of skin cancer, and the same is true for using mobile phones, not advocating everyone to abandon mobile phones, but advocating the correct use of mobile phones to reduce excessive exposure to mobile phone radiation.
Second, always play with the mobile phone before going to bed, and 4 problems may come to the door
Playing with mobile phones and swiping back videos before going to bed is the daily state of many people, and the time for playing and playing quietly slips away, and when they come back to their senses, they often lie in bed for an hour or two.
Playing with your mobile phone before going to bed not only consumes time, but also consumes your health.
1. Induce glaucoma
Wu Minhui, an ophthalmologist at the Second Hospital of Foshan City, Guangdong Province, reminded that looking at a mobile phone at close range and in a dark environment for a long time will cause intraocular pressure to rise, and a long-term increase in intraocular pressure will cause optic nerve damage and cause angle-closure glaucoma.
2. Easy to get otolithiasis
Lin Xikang, chief physician of the Department of Neurology of Fujian Provincial Hospital, pointed out that staying in bed for a long time and playing with mobile phones will affect the blood supply to the inner ear, which will cause the canalith to loosen and fall off, which is easy to cause otolithiasis. When I get up and lie down, I suddenly feel like the world is spinning, and I feel dizzy.
3. It can cause bone hyperplasia
Zhang Fengqi, chief physician of the Department of Foot Surgery at the Third Hospital of Hebei Medical University, said that bowing his head to play with his mobile phone may cause the bones in the back of his head to mutate and grow new "horns", that is, bone spurs, which may bring pain to the cervical spine and back.
4. Sleep is low-quality
According to the 2022 White Paper on Healthy Sleep in China, 68.9% of people go to bed late because of their mobile phones.
Researchers from Harvard University in the United States have also confirmed that the secretion of melatonin will stop when people are exposed to strong blue light. Using appliances with electronic displays 2 hours before bedtime can reduce melatonin secretion by 22%, which in turn affects normal sleep.
3. Do you have to play with your mobile phone before going to bed? Please do these 3 points well
Many people have developed the habit of playing with their mobile phones before going to bed, and they can't fall asleep without playing with their mobile phones a few times.
1. Prefer electronic devices with large screens
Electronics with large screens can reduce eye fatigue, so try to look as large as possible when you have options, such as using a tablet instead of a phone.
2. Pay attention to the distance between the screen and your eyes
Keep an appropriate distance between your eyes and the screen, and look at your phone at least 30 cm away from the screen.
3. Have soft light around you
When looking at the electronic screen, there should be enough soft light around it, and you must not turn off the lights to see, which will cause the greatest damage to the eyes.
For modern people, it is indeed unrealistic to force the abstinence of mobile phones, but we can control how long we play with our phones. When you look at your phone before going to bed, you can set a reminder alarm clock and play for 20 minutes.
After playing with the phone, you can put the phone at a distance of an arm's arm, not to prevent radiation, but to keep the phone out of reach and not affect normal sleep.
