The latest research from Georgetown University in the United States, combined with previous studies, shows that mobs increase the potential risk of brain tumors. Coincidentally, medical experts from the rebru University Hospital in Sweden also released research results, saying that they analyzed the global related research of 1 1 and found that using mobile phones 1 hour every day is enough to increase the risk of brain tumors in the long run.
Experts remind that when using headphones, use hands-free headphones to answer, and remember not to put the phone close to your ear five seconds before the call is connected.
2. "Mobile phone dermatitis"
Many patients will have unexplained rashes on their ears or cheeks, and even some patients will have similar rashes on their fingers. The doctor suspected that skin allergy might be caused by excessive use of mobile phones.
In this regard, the British Dermatology Association quoted published research data as saying that after long-term use of mobile phones, prolonged contact with nickel on the surface of mobile phones may lead to allergic reactions on the skin, resulting in a red or itchy rash, which is called "mobile phone dermatitis".
3. Eye injury
Playing mobile phone in bed will cause great pressure on the left and right eyes, oppress blood vessels, cause insufficient blood supply, and soon lead to vision deviation between the left and right eyes. Looking at the screen of a mobile phone in a dark environment, due to the strong light of the screen, will cause strong stimulation to the eyes, make the eyes tired, and will be nearsighted or even astigmatism within one month.
4, sleep reduction
Adequate sleep is a necessary guarantee for a healthy life. Because when playing mobile phones, the production of melatonin (a substance that directly affects the quality of sleep) secreted by the pituitary gland will decrease, resulting in reduced sleep and even inability to fall asleep. I believe that people who play mobile phones until midnight or even later have a deep understanding-they are not sleepy at all and don't want to sleep.
5, affect the work, reduce creativity, affect efficiency.
The researchers found that if people were interrupted by phone calls while concentrating on their work and study, it would take 15 minutes to get back to work and study. More seriously, if people have to put down their work to answer because of the ringing of the phone, it will seriously affect people's work efficiency and mood. Research shows that the interference of cell phone ringing at work may reduce people's creativity and memory.

Reduce the harm of playing mobile phone before going to bed
First of all, don't play with your mobile phone on your side. Lying on the side has the greatest pressure on the eyes, which will cause visual deviation between the left and right eyes. In addition, the oppression of the pillow on the eyes will cause insufficient blood supply, and the eyes will feel swollen after a long time, which is prone to short-term image overlap.
Secondly, we should turn down the brightness of the mobile phone screen. Hide in bed and play with your mobile phone at night, and try to turn down the light of your mobile phone. The contrast between the bright screen and the dark environment is too great, which will make your eyes tired.
It is best to tilt the screen down 45 degrees. Don't point the phone screen at your eyes. It's best to lean down about 45 degrees, and don't lean up, otherwise the neck will be sore after stretching for a long time. In addition, keep your eyes at a distance of 30cm to 50cm from your mobile phone.
In addition, try to set the phone to night mode. Set the browser and reader to night mode at night. It is best to choose a cool color and avoid a warm background. The greater the color difference between the two colors, the more wasted the eyes. The greater the color difference between black and white, the most wasteful of eyes.
Don't play with your mobile phone on your stomach. Playing on your stomach will affect the blood circulation of your elbow and brain, and may also cause inertia ischemia above the cervical vertebra. In addition, prone posture is easy to induce fatigue and it is difficult to fall asleep.
