What happens when you lie down and play with your phone every day?

Netizen @eat a melon has shared a personal experience.

During the epidemic, she spent about 8 hours a day in bed playing with her mobile phone, playing games, watching videos, especially playing games. She always pressed her little finger against the phone when playing games. After a long time, she gradually felt a little uncomfortable in her hands. , The little finger is often numb and painful, and even grooves appear.

She didn't rush to the hospital for a CT scan until her entire palm couldn't work harder. The doctor warned that, fortunately, her bones have not been deformed, so she should not lie on the bed or play with her mobile phone on her stomach. If there is serious deformation, it may become a claw-shaped hand.

1. Is it useful for the eyes to turn on the "dark mode" when playing with mobile phones at night?

"Dark Mode" can save a certain amount of power in the use of OLED screens, but can it protect eyes? In fact, the dark mode has a certain effect in a low-light environment. The stimulation of light to the eyes will be much less, and the damage to the eyes may also be relatively reduced.

In addition, Dark Mode can improve the sensitivity of people with low vision to bright light . For example, some people with photophobia may experience migraine symptoms when exposed to strong white background light. Or for people who are nearsighted, it may be easier to read bright text on a dark background.

However, despite this, whether the dark mode will make the eyes more comfortable or not varies from person to person , and there is no accurate conclusion for the time being. No matter whether it is turned to dark mode or not, as long as it is comfortable to use when playing with the phone at night. But it is not recommended to play with mobile phones before going to bed.

2. Swipe your phone for 8 minutes before going to bed, your brain will be excited for 1 hour

According to the "2020 White Paper on Sleep of Chinese Residents during the National Stay at Home Period", during the epidemic, the Chinese people's sleep time was delayed by 2-3 hours as a whole, and more than 60% of them would play mobile phones before going to bed.

But you know what? The dangers of playing with mobile phones before going to bed are very great.

A sleep evaluation platform in the United States conducted a survey on the sleep status of 2012 people, and the data showed that 78% of people had "retaliatory sleep procrastination", which means that they postpone going to bed to do things they don't have time to do, and other unimportant things.

By recording the REM sleep period and the time it took to fall asleep after the participants played the app for 8 minutes, the researchers found that the most influential app, after users used it, took an average of 1 hour to fall asleep.

The researchers explained that playing a mobile phone before going to bed stimulates the release of adrenaline and dopamine, which makes people feel good, thus delaying sleep time.

So, how exactly does playing mobile phone affect sleep?

Guo Xiheng, chief physician of the Respiratory and Sleep Center of Beijing Chaoyang Hospital affiliated to Capital Medical University, said that sleep requires a dark environment, but mobile phones emit light, which runs counter to the sleep environment and disrupts the sleep environment. The blue light emitted by mobile phones can affect the light-sensing effect of the retina, thereby reducing the release of melatonin in the brain. Insufficient release of melatonin will prolong the time it takes to fall asleep and reduce sleep quality.

3. In addition to affecting sleep, there are 5 consequences that cannot be escaped

Playing with a mobile phone before going to bed still affects sleep lightly, but there are 5 more serious consequences that cannot be avoided.

1. Increased risk of depression

A South Korean study found that prolonged use of mobile phones before bed was associated with a 20% higher risk of depression and a 14% higher risk of anxiety. A study published in "Nature Neuroscience" in my country also pointed out that night lights can interfere with the "anti-reward center" of the brain, causing more negative emotions and increasing the risk of depression.

2. Increased Thyroid Risk

A study in Cancer found that nighttime light sources increase the risk of thyroid cancer, especially for women. Light sources at night include night lights, outdoor lights, blue light emitted by electronic products, etc.

3. Indirectly increases dementia risk

Playing mobile phones before going to bed will inhibit the secretion of melatonin in the human body, resulting in difficulty falling asleep, frequent waking up, and seriously affecting the quality of sleep. Lack of sleep for a long time will cause metabolic disorders, causing metabolites and toxins to accumulate in the body, which may eventually induce inflammation, lead to the death of brain cells, and indirectly increase the risk of Alzheimer's disease.

4. Affects vision

Playing with a mobile phone before going to bed will greatly reduce vision, especially if you play with a mobile phone on your side for a long time, there will be a large gap in the vision between the left and right eyes. In severe cases, it may even cause retinal blood vessel blockage and cause eye stroke.

5. Will be ugly

Playing with mobile phones before going to bed will expose the skin to blue light for a long time, which will penetrate deep into the skin over time, resulting in enlarged pores, rough skin, increased wrinkles, and accelerated aging.

4. I really can't bear it, how to play the mobile phone correctly?

However, for modern people, mobile phones are already a necessity in life, and it is even more impossible not to play mobile phones at night. So, in order to reduce the harm of mobile phones to the body, we can do this:

1. Duration

Control the time, the shorter the time of playing with the mobile phone, the better, and try to avoid using the mobile phone for a long time. When playing with mobile phones at night, do not turn off the lights, and keep the indoor lighting adequate.

2. Posture

Do not lie down or play with your phone on your stomach, so as not to increase the burden on the spine and shoulders, and increase the risk of periarthritis of the shoulder and cervical spondylosis. The correct posture is to keep the chest and abdomen close, the center of the mobile phone screen is parallel to the line of sight, try not to look down on the mobile phone for a long time, so as not to cause cervical pain.

Playing with your mobile phone for a long time every day, have you noticed any bad changes in your body? If it has already happened, then it is necessary to reduce the time of unnecessary use of the mobile phone as soon as possible. After all, an hour or two less on your phone is nothing compared to your physical health.
