Uncle Zhang, 65 years old, got a job as a security guard after retirement, and could lie down in the duty room at night and take a nap when no one was around. He likes to put his phone to his ear to listen to novels and TV series before he goes to sleep, and recently he has found that he always has headaches and dizziness from time to time.
His wife reminded him that he had something in his brain because he put his mobile phone next to his pillow every day, which scared Uncle Zhang enough, could it be that his recent dizziness and headache were really caused by his mobile phone?
1. WHO's 28-year study shows that mobile phones have nothing to do with brain cancer!
Nowadays, technology is developing rapidly, and smartphones have become an indispensable part of people's lives. While mobile phones bring convenience to people's lives, there are also many people who worry about the negative health effects of regular use of electronic products, especially the debate about whether mobile phone radiation can cause cancer.
The claim that mobile phones cause cancer is actually mainly derived from the following two studies, one published by the Center for Environmental Epidemiology Research in Barcelona, Spain, which pointed out that routine use of mobile phones does not increase the risk of brain tumors. However, frequent use of mobile phones may increase the risk of meningioma by 2.01 times and glioma by 1.91 times.
Another study, conducted by Sweden cancer experts, found that people who used mobile phones for more than 25 years had three times the risk of glioma compared to people who used mobile phones for less than 1 year.
In this regard, Ruan Jian, deputy chief physician of the Department of Neuro-Oncology of the Affiliated Cancer Hospital of Chongqing University, refuted the rumor, according to the current research, there is no clear causal relationship between the pathogenesis of brain tumors and the use of mobile phones. It is known that the occurrence of brain tumors is related to ionizing radiation such as X-rays, ultraviolet rays, and gamma rays, which can damage the body's DNA and cause damage to the body. The radiation generated by mobile phones is electromagnetic radiation, which has low power and low energy, and will not damage the cell structure.
Due to the controversy over the research on brain tumors caused by mobile phones, the International Agency for Cancer (IARC) under the WHO also restarted the study of whether mobile phones cause cancer a few years ago, and the results of the study were published in the journal Environment International on September 3 this year.
Researchers from Australian institutions commissioned by WHO evaluated more than 5,000 studies in 22 countries from 1994~2022, involving 63 high-quality research results. In the end, it was found that with the increase of mobile phone use time, cumulative call time and number of times, mobile phone radiation did not increase the risk of brain tumors, neck tumors and other brain diseases.
According to a report by Phoenix News, the International Agency for Cancer will also announce next year whether it will re-remove the obvious category 2b carcinogens from radio frequency electromagnetic fields generated by wireless communication devices such as mobile phones.
Second, playing with mobile phones before going to bed for a long time may lead to 5 problems over time
According to the survey data of the Social Survey Center of China Youth Daily and the questionnaire network, 84.8% of young people have the habit of playing with mobile phones before going to bed. Among them, 84.1% will continue to use their mobile phones when they feel sleepy, which shows that it is very common for people to play with mobile phones before going to bed, however, playing mobile phones before bed for a long time may bring these harms.
1. Impaired vision loss
Many people like to turn off the lights and play with their mobile phones, which will have a great impact on their eyesight, and can easily cause problems such as visual fatigue, dry eyes, glaucoma, and macular degeneration. Wu Minhui, an ophthalmologist at the Second Hospital of Foshan City, Guangdong Province, pointed out that looking at a mobile phone at close range or in a dark environment can easily increase intraocular pressure, which may damage the optic nerve in the long run, leading to angle-closure glaucoma, and even blindness in severe cases.
2. Decreased sleep quality
The blue light of the mobile phone has an alert effect, which can reduce the secretion of melancholic, which will lead to a delay in falling asleep, affect the quality of sleep, and cause too many dreams, unsteady sleep, easy to wake up, etc., which is also called "circadian rhythm disorder" in medicine.
3. It is easy to get cervical spondylosis
Playing with mobile phones in bed is also not good for spinal health, which can easily cause misalignment and sprains, which will increase the risk of cervical spondylosis.
4. Increase the risk of dementia
Studies have found that playing on a mobile phone for 2 hours before bed can reduce melatonin secretion levels by 22%, which in turn affects sleep quality. Long-term sleep deprivation will make the brain unable to remove metabolic wastes and toxins in time, which can easily cause brain cell death and increase the risk of dementia for a long time.
5. Cause mood disorders
Playing on your phone before bed can also affect your mood, and some studies have found that insomnia and mood disorders are cause and effect of each other, forming a vicious circle. People who often suffer from insomnia and poor sleep are more likely to have emotional problems such as irritability, depression, and anxiety.
3. Pay attention to these 4 points to reduce the health hazards of mobile phones
When many people play with their mobile phones at night, they are reluctant to put down their mobile phones even though their eyes are very tired. In view of this situation, you can do these details well to reduce the damage to eye health.
1. Turn on the lights to play
Turning off the light and playing with the mobile phone is very harmful to the eyes, if you feel that the top light is too bright, you can turn on the small desk lamp, as long as you are not playing with the mobile phone in the dark state, and at the same time you can turn down the brightness of the mobile phone.
2. Sit and play
It is easy to unconsciously bring the phone closer to you while lying down and playing with your phone, you can sit up or use a stand to stay away from it while playing with your phone.
3. Blink more
Staring at the phone for a long time can easily dry the eyes, it is recommended to blink more in the process of looking at the phone, blinking can promote the secretion of tears and reduce the fatigue of the eyes.
4. Control time
The time to play with the mobile phone is controlled for about 20 minutes each time, and the time is up for 20 seconds, and it is best not to stare at the mobile phone for more than 4 hours a day.
The radiation produced by mobile phones is non-ionizing radiation and is not directly related to the occurrence of brain tumors. However, it is not recommended to play mobile phones for a long time in daily life, otherwise it will also have a negative impact on health.
