What are the hazards of playing mobile phone before going to bed?

It does a lot of harm, especially to the eyes. I used to have a vision of 5.0, but now I have glaucoma and cataracts. I am really afraid that I will be blind in the future.

Watching mobile phones at night has become the norm in our lives, and countless people brush dramas, watch short videos and play games. Followed by the emergence of various unhealthy symptoms of the body. So, what are the hazards of playing mobile phone before going to bed?

1, vision loss

When I sleep, I lie down and play with my mobile phone, and my eyes are close to the electronic screen. When you concentrate on the screen, the number of blinks decreases, which easily causes dry eyes, tingling and photophobia. After a long time, it will increase the curvature of the lens and lead to blurred vision.

Watching mobile phones for a long time may cause "dry eye" in addition to decreased vision. I wonder if anyone has seen this. Watching the mobile phone for too long will make your eyes dry and make people uncomfortable. This may be dry eye caused by watching mobile phones for a long time.

2, affect the quality of sleep

Playing mobile phone at night may lead to poor sleep quality. Brushing a mobile phone can easily stimulate the cerebral cortex and make brain cells in an active and excited state. If you brush content that is too funny, too sad or too exciting while watching your mobile phone, you may be tempted to browse for a while.

3, biological clock disorder

Many people are always used to playing mobile phones before going to bed, but they don't know that this bad behavior will damage their health. If you always have this kind of behavior, after a period of time, you will find that your biological clock is disrupted, and there will be autonomic nervous dysfunction, and the quality at night will become very low, which needs to be highly valued.

4, 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.

5, cervical pain

If you often play mobile phones before going to bed, you should stop playing mobile phones if you find that your cervical spine is sore after a while. Many people will sleep on their side when playing mobile phones, and unconsciously waste a lot of time while maintaining a certain posture of the cervical spine.

If the time is too long, it may cause the local blood circulation to be blocked, and the negative impact of failing to supply blood in time is obvious, which may lead to the feeling of soreness and pain in the cervical spine.

6. Numbness of fingers

I don't know if you have this situation, but I am very obvious now. I often press the button and my thumb hurts. Excessive use of mobile phones and frequent texting can cause discomfort such as sore thumb, numbness or swelling.

7. Increase the risk of dementia

The light of mobile phone will inhibit the secretion of melatonin. Some surveys have also found that watching mobile phones for two hours before going to bed will reduce the melatonin secretion level by 22%, which will lead to sleep problems such as difficulty in falling asleep and frequent waking up.

In addition, for office workers, the time to get up every day is basically fixed. If you play mobile phone before going to bed, you will stay up late, sleep time will be shortened, and you are prone to lack of sleep.

Long-term poor sleep or lack of sleep will make the brain unable to remove some metabolic wastes and toxins in time. Long-term accumulation of these substances will induce inflammation, lead to brain cell death, and be more prone to dementia.

How can we reduce the harm caused by watching mobile phones at night!

The best way is to get rid of the habit of watching mobile phones. But for those of us who are used to this lifestyle, it is really difficult. So try the following method.

1, don't look at your mobile phone on your side.

Try to avoid playing with mobile phones when lying on your side. You can choose a supine posture and put a pillow on your elbow so that all parts of your body can be in a comfortable state. Be careful not to point the phone screen at your eyes. You can tilt the phone slightly down 45 degrees to relieve muscle pressure.

Step 2 control time and distance

When using the mobile phone, keep your eyes at a distance of 30 cm to 50 cm. Use your mobile phone intermittently and take a break every 40-50 minutes.

3. Turn down the brightness of the mobile phone screen.

Play with your mobile phone before going to bed, and try to turn down the brightness of your mobile phone. Too bright screen and dark environment contrast too much, easy to make eyes tired.

Step 4 turn on the light

It is best to turn on a light when using a mobile phone at night, which avoids the irritation to the eyes and reduces the harm to other aspects. The pupil of eyes should be narrowed when looking at objects at ordinary times and enlarged when watching mobile phones at night, which is contrary to the physiology of eyes.

Step 5 do exercises

In order to rest my eyes, I did eye exercises at school. I can also look at the distance, 5 meters away, for a few seconds after playing with my mobile phone for a while, and then look at my nose to relieve eye fatigue.

The above methods can only play a role in relieving, and what can really be improved is to get rid of the bad habit of watching mobile phones at night. For the sake of future health, you should still worry about your future health.
