How to use mobile phone correctly

The first move to use mobile phone correctly

Don't bring other things, especially food, when you talk or send or receive text messages. Be careful not to get sick through your mouth. At the same time, try not to lend your mobile phone to others to avoid cross-infection of germs.

The second move

It is best to gently wipe the keyboard, screen and other parts of the mobile phone with a cotton swab stained with medical alcohol every week. If you can't bear to spend a lot of money to buy a mobile phone, you can also go to the mobile phone customer service to clean it with ultraviolet or ozone.

The third measure

Keep the phone at least 5 cm away from your body when talking.

The fourth move

Don't put your mobile phone next to the pillow when you sleep. Pregnant women had better not use it.

The fifth move

Always change your body direction when you speak. This can disperse the radiation received by the body.

The sixth trick

Text more and call less. This will reduce the contact time between the phone and the head.

Harm of mobile phone 1, eye injury

A, lying in bed playing with a mobile phone will cause great pressure on the left and right eyes, and pressing blood vessels will cause insufficient blood supply, which will soon lead to vision deviation between the left and right eyes.

B. Looking at the mobile phone screen in a dark environment, due to the strong light of the screen, it will cause strong stimulation to the eyes, make them tired, and they will be nearsighted or even astigmatism within one month. Especially for children under 3 years old, watch bright things for less than or equal to 15 minutes, so as not to damage their eyesight.

C, relevant information shows that reading words and pictures with mobile phones is more eye-catching than reading books and newspapers, that is, reading things with mobile phones requires greater concentration.

2, affect intelligence

In the blood circulation of human body, it is necessary to keep the balance of positive and negative charges. However, the constant electric radiation from mobile phones will have an impact on this balance. In the long run, it will reduce your immunity, make you tired easily, and make your body in a sub-health state. Because the balance of positive and negative charges is inseparable from nerve conduction, when nerve conduction in the brain is destroyed, intelligence will decline.

3, sleep reduction

Adequate sleep is a necessary guarantee for a healthy life. Because when playing mobile phone, the production of melatonin secreted by pituitary gland (a substance that directly affects the quality of sleep) will decrease, resulting in less 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.

Step 4 get sick easily

The mobile phone will emit electric radiation, and its radiation intensity has nothing to do with the remaining power, but has a certain relationship with the signal intensity. The greater the signal intensity, the higher the radiation intensity, and the greater the harm to the body. Electric radiation can make cells unable to carry out normal metabolic activities, which will damage nerve function and cardiovascular system. It can lead to tumor, heart disease, Alzheimer's disease, tinnitus, hearing loss and so on.

5. Damage to the skin

Because of the influence of radiation on cells, melanin will deposit and grow spots over time. It can also lead to decreased immunity, bacterial growth, rough skin and even acne.

6, cervical reverse arch

Cervical reverse arch is a common cervical spondylosis. The physiological curvature of cervical spine is normal. If there is no physiological curvature, it even bends in the opposite direction, which is called anti-bow. Therefore, it is a bad habit to play mobile phone in bed for a long time, so don't play mobile phone in bed for the sake of health.

Step 1: Use the mobile phone correctly. When the mobile phone exhales, it is best to keep the mobile phone away from the head first to avoid radiation to the head when the mobile phone emits high power.

2. Try to reduce the time of using the mobile phone every time and the number of times of using the mobile phone every day. When you need to talk for a long time, it is more scientific to alternate left and right ears or use headphones.

3. When the cell phone signal becomes weak, the cell phone will automatically increase the transmission power of electromagnetic waves, so don't put your ear near the cell phone at this time.

4, don't answer the phone in the corner, the signal coverage in the corner of the building is poor, so it will increase the radiation power of the phone to a certain extent.

5. Pick up the phone and don't walk around. Frequent movement of position will cause fluctuation of received signal strength, resulting in unnecessary short-term high-power transmission.

Tips for playing mobile phone correctly 1. Look at the phone in the right posture. When using a mobile phone, it is best to stand or sit with your back straight, and hold the phone parallel to your eyes to avoid bowing your head for a long time. Usually you can raise your head and stretch your neck, sing, massage, exercise your chin muscles and reduce fat accumulation.

2. Browse the screen at night and try to switch to night mode. We perceive that fonts are recognized by color difference reaction, and the greater the color difference between the two colors, the more troublesome it is. At the same time, if you can only lie down, try not to use your mobile phone to play games or surf the Internet. If the elbow is tired, you can continue to hit the elbow with the quilt. And stare at the phone screen for 30-45 minutes, and take a break 1 hour.

In order to prevent neck and shoulder pain, it is best to reduce the time of using mobile phones and try not to play for more than one and a half hours. Arms, shoulders and neck are prone to stiffness and pain. Look up, lift your neck, twist your neck back and forth, and move your fingers. Don't be stiff in one position for a long time. In addition, if you make a phone call, don't hold your mobile phone in your hand. Use earplugs instead.

4. When playing with mobile phones and ipda, choose to stick a blue film. Electronic products will emit blue light that is harmful to vision health. Blue light blocking materials are used in the blue light prevention film, which can effectively reduce direct blue light, slow down visual fatigue and achieve the purpose of protecting vision. Sticking the anti-blue film to watch the screen of the mobile phone makes the eyes more comfortable.
