Eight hazards of playing mobile phone before going to bed

There is a group of people called "late-night mobile phone party". They are used to playing mobile phones, Weibo, WeChat and games in bed before going to bed. . But refused to go to bed at once. Although playing mobile phone can bring us a lot of fun, do you know the harm of lying down and playing mobile phone before going to bed? I will come to you one by one!

1. affects the biological clock.

Using mobile phones, tablets or other electronic products that emit light over 1 hour in bed will reduce the total amount of melatonin produced by people by about 22%. Once human melatonin is suppressed to this extent, then human physiological cycle will also be affected. The direct impact is that people are always in a shallow sleep state, and even greatly reduce people's sleep time. In other words, after playing the mobile phone for 1 hour, you may have to play it for another 3 hours because you can't sleep.

2. Chronic strain

The neck droops excessively, the body bends unnaturally, and the neck leans forward more and more. This makes the sternocleidomastoid muscle of human neck stretch forward continuously, and it will be in a state of chronic congestion for a long time. Over time, it is easy to oppress vertebral artery, induce cervical spondylosis and cause chronic strain.

3. Affect vision

Lying flat on the left and right has the greatest pressure on the left and right eyes, and less than a month will lead to the deviation of vision between the left and right eyes (why do some people wear glasses with different degrees, while people are born with the same degree of eyes? It is because some people like playing mobile phones, reading novels and reading comics sideways. ) The pressure of the pillow on the eyes causes insufficient blood supply. After a long time, eyes will feel swollen, and short-term images will overlap. This is not enough eye drops! So really, for our eyes, really don't!

4. Cervical reverse arch

We normal people all have physiological curvature of cervical spine. If there is no physiological curvature or even bending in the opposite direction, it is called "anti-bow". "Cervical spondylolisthesis" is the most common pathological basis of cervical spondylosis. High pillow can bend the head forward, increase the stress of lower cervical vertebra, and accelerate the degeneration of cervical vertebra. And bad living habits such as lying on your back and watching TV, surfing the Internet for a long time, lying on your back and playing with your mobile phone, pulling the cervical vertebra for a long time, etc., will also lead to the reduction, straightness and even retroflexion of its curve.

5. Affect intelligence

The radiation of the mobile phone is relatively large, including the radiation of the screen in radiation 2 and the signal reception of the body. The blood in the human body needs to maintain the balance of positive and negative charges, and the radiation of the screen will have a slight impact on this balance, although it is not big, it is still harmful.

After a long time, it will cause adverse reactions such as decreased immunity, fatigue and nausea.

Facing the mobile phone for a long time will also affect your eyesight. It is recommended to play less mobile phones when sleeping at night.

In addition, the radiation received by mobile phone signals will affect people's brain nervous system, which will reduce their intelligence after a long time.

Damage the skin

The radiation of mobile phones to people should not be underestimated. When people use mobile phones, they are close to their faces, which will have a certain impact on their skin. They are not sure if they will get spots, but they are definitely bad for the skin and prone to acne.

7. Numbness of fingers

Frequent keystrokes, sore thumb. Excessive use of mobile phones and frequent texting can cause discomfort such as sore thumb, numbness or swelling.

8. disgust

Cell phones can cause allergies. Some people have inexplicable skin allergies after using their mobile phones for a short time. After inspection, it was found that it was caused by some metals such as nickel on the mobile phone.

Mobile phone Weibo control must see 6 tricks to protect eyes.

Recently, it is widely rumored on the Internet that although the brightness of the mobile phone screen itself is enough at present, the display effect will still be affected after the screen is coated, and the wear and tear after long-term use will further affect its display effect, which will inevitably increase visual fatigue and even damage vision.

Because the protective film can easily refract the light on the screen of the mobile phone, staring for a long time will cause visual fatigue.

Especially outdoors, coupled with insufficient screen lighting, it is even more difficult to see the font. In this way, the ciliary muscles are often in a state of tension, the convexity of the lens is always large, and the eyes are prone to fatigue due to excessive adjustment.

Over time, the convex lens can't return to its normal state, which will form or aggravate myopia.

In fact, sticking a film on a mobile phone is an act of gilding the lily, and the best use of a mobile phone should be to return it to its true colors.

1, choose a soft background color.

Too bright colors on mobile phone screens and mobile phone web pages will invisibly increase the working intensity of eyes. You can try to adjust the brightness and contrast of the mobile phone screen and change the background color, so that the screen brightness is softer and has a certain contrast, but it will not be too dazzling.

It is best to adjust the background color of the webpage to soft tones such as brown and orange. In addition, it's best to make the font of the mobile phone bigger.

2. Don't play with your mobile phone in the dark.

Improving the environment also helps to relieve eye fatigue. I believe you have such an experience. When you turn off the lights and watch TV in the dark, your eyes will soon get tired.

Because the light contrast between the display and the background is too big, it increases the fatigue of the eyes. Therefore, in the dark, especially at night, although the mobile phone has brightness, it must turn on the lighting and don't "work in the dark".

3. Pay attention to the brightness of the mobile phone.

Pay attention to the "beautiful position" of the mobile phone, and choose a position where light or natural light will not reflect to the eyes through the screen of the mobile phone.

Step 4 control the use time

This is the basic method to prevent eye fatigue. If you can't control the use time, all other interventions will be discounted.

5, overlooking to relieve eye fatigue

Ensuring adequate sleep, closing eyes moderately and farsightedness are the basic methods of eye protection. After using it for 45 minutes to 1 hour, be sure to stop for a few minutes and look far away.

6. Blink frequently and do more eye exercises.

Besides looking at the distance, doing eye exercises with your mobile phone 1 hour or so, and persisting for a long time is also a good way to protect your eyes.

It is unrealistic for busy adults to do eye exercises four times in a row. You can simply do the action of "pressing the temple and scraping your eyes in turn", which will dredge the meridians, improve the blood circulation of the eyes and be of great benefit to the metabolism of the eyes.

Under normal circumstances, people blink about 15 times per minute, but when operating mobile phones, especially when playing games, their attention is highly focused on the screen. Unconsciously, the frequency of blinking will be significantly reduced, leading to excessive and rapid evaporation of tears, dry eyes and other problems. Therefore, mobile phones should "control" their blinking more consciously.

How to use mobile phones healthily

Mobile phones have become a necessity in our daily life, but the problem is that mobile phones will produce radiation that has an impact on personal health, which many people should pay attention to. How to use the computer healthily?

Dr Ronald Herberman of the University of Pittsburgh recently gave several suggestions on the safety of mobile phone use.

1, text more and call less. This will reduce the contact time between the phone and the head.

2. When sleeping, don't put your mobile phone next to the pillow. Pregnant women had better not use mobile phones.

The mobile phone is almost dead and charging, so it's better not to make a phone call.

4. When talking, the mobile phone should be at least 5 cm away from the body. Because at a distance of 5 cm from the body, the intensity of the electromagnetic field amplitude of the mobile phone is 1/4, while at a distance of 9 cm from the body, its intensity is only 1/50. So it's best to use speakers or headphones. In both cases, the radiation of the mobile phone is only1100 of the standard mobile phone.

5. If you have to carry your mobile phone, please make sure that the keyboard is facing your body and the back is facing the outside of your body. The electromagnetic field transmitted in this way can stay away from your body.

6. When you speak, change your body position regularly. This can disperse the radiation received by the body.

In addition, when the other party picks up the mobile phone, put it on the ear to reduce the radiation released by the electromagnetic field.

7. Besides not walking around and using mobile phones, try to avoid using mobile phones in cars or trains.

Because at this time, the mobile phone keeps trying to connect the interrupted signal, which will maximize the radiation.

Five misunderstandings of mobile phone radiation protection+how to use mobile phone healthily

Mobile phone radiation, a public concern. Especially for the elderly, students, pregnant women and other special groups, related mobile phone radiation protection products have been very popular.

Recently, a colleague of mine joined the ranks of pregnant women and instantly changed from invincible Xiao Qiang to a national treasure panda. All kinds of health foods and radiation protection tools will be ready in a short time.

The blue radiation suit is her initial "protector". Ah Ya, I'm curious about how useful this thing is, so I gave it a try:

Wrap your phone tightly with clothes and dial. . . . . Then. . . . . The familiar bell still rings. I tried it three times and the result was the same. Colleagues expressed the "mood" of Samsung mobile phone signal.

Personally, I gave up and doubted this product (I don't believe it at all! )。 At the same time, it also rejected other radiation-proof peripheral products.

1How can 80 yuan's radiation protection stickers beat 700 yuan's radiation protection suits? It seems that the struggle between special people and radiation is relatively "long".

Below I have sorted out six misunderstandings of mobile phone radiation protection put forward by professionals.

You may wish to know that when you buy, you should know fairly well and don't be deceived by the rhetoric of the merchants. It is quite against the moral bottom line to make money by taking advantage of the weakness of human nature.

1. Can a mobile phone with a metal case protect against radiation?

Anyone with a little knowledge of electromagnetism knows that metal shields electromagnetic waves, so many people choose mobile phones with metal casings to reduce the radiation of mobile phones.

In fact, the radiation of mobile phones with plastic shells and metal shells is the same, because the inside of mobile phones with plastic shells will also be coated with a layer of metal to keep them isolated from the outside world. Moreover, the telephone signal is sent in the form of electromagnetic waves through the antenna, so it has little to do with the material of the mobile phone shell.

2. Is it ok to put an anti-magnetic sticker on the mobile phone?

Strictly speaking, this method is completely useless, because the radiation source of the mobile phone is an antenna, which is just attached to the listener with anti-magnetism. How to be effective?

It is not good to stick anti-magnetic stickers on the antenna, because it will change the magnetic field around the antenna, so that the signal of the antenna will change and the call will not be carried out normally. At this time, the mobile phone has been unable to receive and send signals.

3. Buy a mobile phone with an external antenna?

Whether the antenna is built-in or external, it is not the standard to determine the amount of radiation. Even if the antenna of the mobile phone is external, it is not necessarily weaker than the radiation of the built-in antenna.

Moreover, for mobile phones with built-in antennas, in order to get better call quality in places with poor signals, mobile phone manufacturers often increase the electromagnetic wave emission intensity of mobile phones when designing mobile phones. The consequences can be imagined!

4. Cell phones produced by base station suppliers have little radiation.

Some people think that the radiation of mobile phones produced by base station suppliers will be less than that of other brands. This conclusion is actually untenable, because the GSM air interfaces of all base stations are unified and standardized, and communication can be carried out as long as the signals meet the same requirements and standards.

5. Buy imported mobile phones

Absolute "worship foreign things and flatter foreign countries." The production of all mobile phones must meet the European FTA certification standard, and the radiation amount stipulated in this standard is the same for all mobile phones, so the radiation of imported mobile phones is not necessarily weaker than that of domestic mobile phones.

The six "methods" of radiation protection mentioned above may only reduce the psychological burden and play the role of self-comfort. There is really no scientific basis for careful study.

As the saying goes, it is better to keep fit than to cure a disease. Moreover, there is really nothing good about the special carrier of mobile phone radiation at present, but we can use our brains in our daily life.

Next, Aya introduces the method of using mobile phones healthily, which is not only suitable for pregnant women, the elderly and students, but also suitable for ordinary users! After all, health is the ultimate pursuit of human life.

Cell phone bacteria exceed toilet seat! How to use mobile phones healthily

According to a test result, there are about1.2000 bacteria in every square centimeter of mobile phone. The mobile phone that you always carry with you is smart and harmful to your health.

108 mobile phone detected 240 strains of 10 bacteria, of which 39 strains were pathogenic staphylococcus aureus.

There are about1.20 thousand bacteria stationed in mobile phones per square centimeter, which is more than a doorknob and a shoe. The main pollution part is the key part of the mobile phone.

There are so many pathogens on a mobile phone. It seems that the regular disinfection of mobile phones can not be ignored.

If you want to use your mobile phone healthily, please remember the following tips.

1. 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 for sterilization, or you can go to the customer service department of the mobile phone for cleaning with ultraviolet rays or ozone.

2. Don't press the button and take other items, especially food, during the call or when sending and receiving text messages, and be careful to get sick from your mouth.

3. Many people are used to putting their mobile phones, wallets, keys, bank notes and other items in a trouser pocket, which is easy to cause cross-contamination.

4. Using headphones during a call can reduce the radiation damage of the mobile phone, and can also make the mobile phone minimize the contact with the face and lips to prevent droplet infection.

5. Wash your hands often. Believe it or not, our hands are the biggest home for bacteria and viruses. If you want your mobile phone to be as bacteria-free as possible, please follow the rule of washing your hands frequently.

6. Buy a mobile phone case for your mobile phone.

Some people think that silicone and plastic mobile phone cases can create more gaps, and these gaps will make the already dirty mobile phone even dirtier.

Nevertheless, having a suitable phone case, especially those that completely cover the keyboard, and then cleaning it regularly, taking the phone out of the phone case, and then cleaning the phone case can greatly reduce the bacteria living in your phone.

Eight Common Sense of Healthy Use of Mobile Phone

Mobile phone is a very close partner in our life, and everything has two sides. How to get the benefits of using mobile phones and reduce the harm of mobile phones to human body?

Common sense one: be single-minded when using mobile phones.

Don't bring other things, especially food, when you make a phone call 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.

Common sense 2: disinfect your mobile phone regularly.

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.

Common sense 3: Keep your mobile phone away from your body when using it.

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

Common sense 4: Stand by for a long time and stay away from your mobile phone.

For example, when sleeping, don't put your mobile phone next to the pillow, but put it more than 70 cm away from the bed. Pregnant women had better not use mobile phones.

Common sense 5: Don't fix your body orientation when using your mobile phone.

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

Common sense 6: Don't call if you can send a text message.

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

Common sense 7: Don't make a phone call when the phone is low voltage or charging.

It's best not to make a phone call when the phone is dying or charging. When charging, the radiation is also dozens of times than usual, which will cause harm to the human body. Therefore, when the mobile phone is charged in the power-on state, it is best not to answer or make a phone call.

Common sense eight: stay away from the mobile phone when it thunders and lightning.

Be sure to stay away from trees and charged objects outside when thunder and lightning strike. Generally, tall trees are the targets of lightning strikes, and charged objects are easily struck by lightning. So, please don't forget to turn off your mobile phone and avoid putting it in your pocket.

Conclusion: Today, I will tell you about the dangers of mobile phones. Of course, we can't deny that mobile phones have brought a lot of convenience to our lives, but I hope everyone will treat its harm correctly. Besides, we should eat more radiation-proof food in our daily life.
